  • I can add as an comment: it seems like the request never reach the server.. details
  • Sensible defaults are also worth thinking about.. details
  • It works if i send only the user which has an username, password... but if i try to send the subscription object is not mapped.. details
  • To do this I would recommend using something like SpEL (spring expression language) or create a small class with some basic java reflection.. details

  • Helpful suggestions!.. details
  • Works great, thanks a lot for your help!.. details
  • Your best option so far is the best option.. details

  • Thanks the solution works.. details
  • What does your request look like?. details
  • Thanks for the answer,Ron, but I am really looking for a Java solution since my code is in Java.. details
  • I know that implementation works in Jersey, RestEASY and Spring 3.. details
  • One change that I can think of is not having the class name in xml, that does not look clean, instead you an try put this information in a custom annotation and use that annotation along with a [HandlerMethodArgumentResolver]( URL_http://docs.spring.io/spring/docs/3.2.x /javadoc- api/org/springframework/web/method/support/HandlerMethodArgumentResolver.html) to create the appropriate JavaType and do the unmarshalling there.. details
  • Very excellent solution,i will try this solution without annotations.. details
  • hmm.. DWR looks great.. really good.. but I already have used Spring MVC and exposing POJO's is already done.. And I think DWR takes care of complete communication.. thanx.. :).. details
  • Thanks, but this is not a solutions for me.. details
  • I want Spring to be smart enough to fetch the company using my ConverterServiceFactory before it arrives in the controller.. details
  • I'm just wondering why there is no Utils like method in spring for that.... details
  • Works great, thanks a lot for your help!.. details
  • It shows how to configure OM to achieve correct result.. details
  • Above example is just a simple Java console app.. details
  • Issue is that users of my library now need to do internal details like decoders and encoders and configuring them in spring each time a new class is added.. details
  • Above source code is just example, which shows that above solution works properly for Enums.. details
  • Is there anyway to have this be automated like it would be with @JsonSerialize?. details
  • Perhaps it only understands application/x-www-form-urlencoded bodies or you need to tell your Spring controller somehow that the request is in format of application/json?. details
  • Please post your server stack trace.. details
  • Please show the code of how you are posting the JSON content to the server.. details
  • It helped!.. details
  • With whatever you are using to add dependencies (like Spring) to your project or web app, just add the Jackson libraries in the same way.. details
  • Post your "Property" class code too please.. details
  • IMHO it would make a good addition to Spring.. details
  • I wasnt really that interested in the Spring side of things unless the reason is purely spring related?. details
  • With this simple JSON: { aBoolean: true }, I am receiving a full "MyEntity" object, with a null "aVeryBigString" property.. details
  • Thank you!. details
  • But you gave a great answer.. details
  • I ended up upgrading to Jackson 2, which required me to upgrade another tool (Spring Integration) to an unofficial release - but all works.. details
  • With Spring we are dealing with simple POJOs.. details
  • What is the stacktrace if any in server logs and how did you make that request , post the JS code also!!!. details
  • Your JSON contains a "property" value and property only contains "name" and "age" You should remove the property from your JSON.. details
  • Are you using any web frameworks like Spring MVC?. details
  • This answer should be number one, let Spring do the work for you!. details
  • Thanks for your reply.What I have to change ?. details
  • Post your configuration... Also please specify which Spring and Jackson version you are using.. details
  • Also if you look inside the source code for org.springframework.amqp.core.Message you'll find a method with signature private String getBodyContentAsString() which does it like this: return new String(body, ENCODING); ... therefore this should suffice as well: System.out.println(new String(message.getBody(), Charset.defaultCharset().name())).. details
  • Also, yes: the webservices should be secured.. details
  • That doesn't look like JSON.. details
  • I appreciate the contribution ... keep it up mate .... details
  • It looks like it's not getting called because you're doing a GET but your method is a POST.. details
  • It's an easy fix to try.. details
  • Yes true Josh, actually your approach does sound good also.. details
  • Just so I understand correctly: your handler method (annotated with @RequestBody) returns a User object.. details
  • Thanks Sean,MediaType is from Spring 3.0,there i will mention application/json.But CharStreams and Closeables api is from google code.IS there any way to write same functionlity with native java code.. details
  • This works for Java collections, however it turns out that the Scala module doesn't support this use case correctly.. details
  • Until the Scala module achieves parity, or until Spring corrects its type propagation, you will need to use a derived class of a Java collection, as indicated above.. details
  • It has support on all major browsers and native mobile clients Apple being pioneers of this technology: As mentioned here excellent support for deployment environments on web and enterprise JEE containers: URL_http://jfarcand.wordpress.com/2012/04/19/websockets-or-comet-or-both- whats-supported-in-the-java-ee-land/ [ URL_http://jfarcand.wordpress.com/2012/04/19 /websockets-or-comet-or-both-whats-supported-in-the-java-ee-land/] .. details

  • Why is the value of my resulting Map another Map rather than a Color object?. details
  • If I just pass a Color in directly without the code to Color map, deserialization works as expected.. details
  • Please let me know how I can deserialize directly to Map[String, Color] successfully.. details
  • I have a Java application which uses Spring's RestTemplate API to write concise, readable consumers of JSON REST services: In essence: CODESNIPPET_JAVA1 .. details
  • I imagine it would let you do something like: CODESNIPPET_JAVA2 .. details
  • -- but I'd love to be told there was something out there that does it reliably with a concise, expressive API, integrated with the HTTP aspect.. details
  • Obviously, in a web project, like a Spring web services project, it is important to have POJO's, but just for unit tests couldn't you just use a generic Jackson JsonNode object?. details
  • thanks for your comment @maxxyme , but annotation @ Provider is enough.. details
  • thanks for your comment @maxxyme , but annotation @ Provider is enough.. details
  • You can take a look at URL_http://docs.spring.io/spring/docs/3.0.x/api/org/spr ingframework/web/servlet/view/json/MappingJacksonJsonView.html#setPrefixJson%2 8boolean%29 [Spring-JSON-Mapping] also.. details
  • I think you can change the JSON property inside spring config file like this: CODESNIPPET_JAVA1 .. details
  • I hope this helped out !. details
  • It will find it because we registered it and it it will then use it to convert the value.. details
  • We simply implement the two methods we care about using whichever flavor of JSON parser we want.. details
  • In this particular case, we don't need all the methods of the CODETERM12 interface, so we can use CODETERM13 which is a helpful default implementation of CODETERM14 .. details
  • Registration is simple in an CODETERM10 annotated method in your CODETERM11 class CODESNIPPET_JAVA1 .. details
  • You rarely receive CODETERM7 as a request parameter, which is why I think you should re-think your design**, but if you have no other choice, you need to register a custom CODETERM8 that will take care of converting the request parameter's CODETERM9 value into your custom type.. details
  • Automatic conversion of JSON form parameter in Spring MVC 4.0.. details
  • If I read the URL_http://docs.spring.io/spring/docs/4.0.x/javadoc-api/org/spri ngframework/http/converter/json/MappingJackson2HttpMessageConverter.html [MappingJackson2HttpMessageConverter-docs] correctly, Jackson JSON conversion is triggered by Content-Type CODETERM3 , which I obviously cannot use since this is a form POST (and I don't control the POSTing part).. details
  • And this is what the MyMessage object looks like: CODESNIPPET_JAVA2 .. details
  • Im developing web application using springMVC 3.2.6 and Hibernate 3.3.1 when I mapped a spring URL pattern as CODETERM1 and request a URL is CODETERM2 the method is working fine as checked in debug mode and CODETERM3 but the JSON is not generated and the output shows as The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ().. details
  • When I mapped a spring URL pattern as CODETERM4 and request the url is CODETERM5 it gives perfect JSON output: CODESNIPPET_JAVA1 .. details
  • Thanks, got it!. details

  • Thanks!.. details
  • If you remove the setter for add(int), wouldn't Spring try to convert, in the case "add": "10", the single value to a List of one item and provide it to the other setter (List)?. details
  • Thanks!. details
  • Best Option So Far** The best option i have come up with so far is to create an Errors container object in the Spring application that contains the Errors enum and also has the json serialize annotation.. details
  • The problem** If i remove the annotation from the Errors enum the Spring project will not return the correct representation of the Errors enum, it will only return the constant variable in quotes.. details
  • Thank you for reply.. details
  • What I am saying is that, if you want to limit calls to that method to only things that are requesting JSON, its probably a good idea to add the proper header (again, I typed that off of memory...please google to verify I didn't typo).. details
  • Ok,thank you very muchSo, are you sayng to me that if I would that my controller method manage only JSON object coming from my view I have to put the element "Accept=application/json" inside my RequestMapping annotation?. details
  • Thanks.. details
  • If I add the header={"Accept application/json"}** then I get exception saying No handler found for the request "request/createPass"** Can anyone please help me out over here?. details

  • URL_http://docs.spring.io/spring/docs/3.2.x/spring-framework- reference/html/validation.html#format [This-is-described-in-the- deocumentation] .. details
  • Spring registers some converters that can convert a String value from a request parameters into a CODETERM10 object.. details
  • There is another option, for Spring, that consists in making the controller method where the serialization is happening @Transactional, this will keep the session open!. details
  • Thanks!. details
  • And it works with more than SqlServer, hibernate, and Tomcat and doesn't require an IDE (altho Spring Tool Suite has a built in GUI shell), but it depends on Maven.. details
  • Tools used: Spring-Roo: for rapid prototyping ( URL_http://projects.spring.io/spring-roo/ [ URL_http://projects.spring.io/spring-roo/ ] ) Spring Tool Suite Spring Maven Tomcat SqlServer Hibernate All of these tools work really well together to develop a web service.. details

  • I mean, the objects are simple, no need to write a custom deserializer for them.. details
  • In my opinion the best way to communicate JSON with the server is using JAX-RS (or the Spring equivalent).. details
  • For my project, Spring 3.0.5 works seamlessly with Jackson 1.6.3 (jackson- core-asl-1.6.3.jar, jackson-mapper-asl-1.6.3.jar) .. details
  • Look at the docs of URL_http://docs.spring.io/spring/docs/3.0.x/javadoc- api/org/springframework/http/HttpEntity.html [HttpEntity] , you will see that you use a MultiValueMap as the Body.. details
  • A simple workaround would be to create by hand the string you want to post as a body : CODESNIPPET_JAVA1 .. details
  • Look at the docs of URL_http://docs.spring.io/spring/docs/3.0.x/javadoc- api/org/springframework/http/HttpEntity.html [HttpEntity] , you will see that you use a MultiValueMap as the Body.. details
  • For testing, I have a controller with 2 methods, one returns an Order for HTTP GET request (this one works) and one that accepts an Order via a HTTP POST (this one fails), e.g.. details
  • I have tried all suggestions from the various discussions on SO but so far had no luck.. details
  • Either you know you use only non primitive types, or some rules (empty String is CODETERM4 , which does not work for everyone) or you have to provide an additional parameter which defines the overridden values.. details
  • Last one works fine for me: The JavaScript application knows which fields have been changed and sent in addition to the JSON body that list to the server.. details
  • I have a POJO that contains a CODETERM2 field, with polymorphic values.. details
  • Map values can take several types, mainly CODETERM3 , other model classes, and particularly other JSON objects represented as CODETERM4 .. details
  • But that is for another discussion :) .. details
  • I'd love it if Spring could do the id to entity mapping for me on my behalf, just as it did for form backing objects.. details
  • For my application, I have successfully created a factory that does what my old property editor did before - converting id's back to entities.. details
  • Before AJAX was popular, it was possible to convert between id's and entities by using a custom property editor and registering that in your controllers.. details
  • Lets say I have a list of objects like this: CODETERM1 .. details
  • It is returned to this kind of method: CODESNIPPET_JAVA1 .. details
  • I am making AJAX call to this controller everything is working correctly as expected but I don't like the naming my JSON is returned.. details
  • I hope this solves at least part of the problem.. details
  • Unfortunately I can't show all of our code, it's pretty long anyways.. details
  • It is a pretty good amount of plumbing to get it all working, but now our controllers are very simple.. details
  • @ResponseBody tells spring to convert its return value and write it to the HTTP Response automatically.. details
  • The detailed post explaining about the spring REST is available at URL_http://smarttechie.org/2013/08/11/creating-restful-services-using-spring/ [ URL_http://smarttechie.org/2013/08/11/creating-restful-services-using-spring/ ] .. details

  • A good question!. details
  • But everything I've ran into (which can get pretty complex, with nested objects in my response) converts perfectly to valid XML or JSON.. details
  • I can't quite tell by your question...but if you're looking to serialize the output more than that, @chrylis is correct in that a custom serializer would be your next move.. details
  • The URL_https://github.com/SpringSource/spring-mvc-showcase [SpringSource- spring-mvc-showcase-project] is also a helpful resource.. details
  • 1) Due to how objects such as maps, root tags and relations are modelled differently in CODETERM7 than in CODETERM8 , the objects to serialize needs to be designed differently to get both tidy CODETERM9 and tidy CODETERM10 .. details
  • The domain model is of complex type and we note that to produce friendly CODETERM3 and CODETERM4 on the same model using CODETERM5 and CODETERM6 respectively tends to give _either_ readable XML or readable JSON 1).. details
  • I want to provide one comprehensive REST API with support for both CODETERM1 and CODETERM2 .. details
  • What's the best way to proceed?. details
  • I would also check in Firebug or the Chrome dev tools that you are sending the correct payload to the server.. details
  • I don't want to be 100% REST compliant, but I do not feel comfortable with providing a custom URL to update each field (especially given that it causes problems when I want to update several fields).. details
  • Sometimes, I just want to update the boolean value, and I don't think that sending the whole object with its big string is a good idea just to update a simple boolean.. details
  • Thanks.. details
  • For instance, the following URL: POST /myentities/1/aboolean/true will be mapped to a method that allows to only update the boolean.. details
  • Another solution would be to split "MyEntity" into multiple resources and just update these resources, but I feel like it does not make sense: "MyEntity" is a plain resource, it is not composed of** other resources.. details
  • Hope our stack users will help me.. details
  • If you're on a recent Spring version, the following should be enough to get things rolling: CODESNIPPET_JAVA1 .. details

  • so what youre saying is that 'account' is part of the URI, but how come the controller value is just '/availability'?. details
  • Does that Spring MVC controller only accept a request body in JSON format instead of the standard application/x-www-form-urlencoded like as standard forms and standard ajax requests send?. details
  • On the other hand, if you need a more flexible and capable framework that has more built-in support for virtually everything in the world, Spring may be just the ticket.. details

  • Can anyone please tell me what is the "standard" or "easiest" way to use @RequestBody with JSON request data and make that bind to an existing / @ModelAttribute populated Command object so that the Command object fully constituted with both old and new data (in the same way it is easily achieved using a full POST http submit).. details
  • I cannot get Spring to both give me the session object and automatically bind the new values from the request.. details
  • Spring would retrieve the already populated command object from my session and then bind (overwrite) those values that have changed as a result of the POST request.. details
  • Everything works, the JSON string is well formatted, and the Controller can create and populate a Command object and populate it with the contents of the JSON request data.. details
  • There must be an easier way.... ;) UPDATE: Found this SOF post today while further researching this problem: URL_http://stackoverflow.com/questions/15124858/spring-partial-update-object- data-binding [Spring-Partial-Update-Object-Data-Binding] It appears there is no known SPRING solution out of the box but a lot of demand to know the best way to handle it.. details

  • I have configured in an Spring 3 application a ContentNegotiatingViewResolver so when I invoke a controller with a URL which looks like json it returns a json object using jackson library .
  • I have a method to which I want to post some json data, that looks like this CODESNIPPET JAVA1 .
  • @RequestBody vs @ResposeBody: As you can see from the name it as simple as that, you only need the @ResponseBody if you are sending a response the the client after the server side method processed the request .
  • It will find it because we registered it and it it will then use it to convert the value .
  • I would like to create a generic json response where I can put in any TYPE and want the response to look like this CODESNIPPET JAVA1 .
  • I'm working on a Spring MVC project and one of the tasks I need to do requires me to have a string of JSON data sent through by the user in a POST request .
  • I know that Spring will deserialize JSON using Jackson to objects, but if I try something like the following: CODESNIPPET JAVA1 .
  • If you have a java model of the JSON object you are expecting then you could replace the String parameter with that in your doSomething declaration, such as @RequestBody If you don't have a Java object that matches the JSON then you could try to get it working by replacing the InputStream type with a Reader and see if that gets you closer to a working solution .
  • I'm working with Spring MVC 3 and trying to use my domain objects to return a json response .

  • Im developing web application using springMVC 3 2 6 and Hibernate 3 3 1 when I mapped a spring URL pattern as *.htm and request a URL is getname.htm the method is working fine as checked in debug mode and system.out.println but the JSON is not generated and the output shows as The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers () .
  • The flow is that when receive a call to entry html, it will check and choose to redirect to /logout.jsp handled by spring security and then redirect to /postLogout.html response JSON resolve to view entry , which is a jsp contain only a json string I would like to know if I can use @ResponseBody in getEntry() without using an jsp to write just a json value?.
  • The behavior of this method is quite clear for me: This method handles HTTP GET Request towards the URL " mapping produces" and the produces element specifies that the method will not accept requests with the header named Accept incompatible with the specified MediaType and that this method produces a new object having JSON format that is put in the body field of the HTTP Response * The new JavaBean object contatin only two inizialized variables and getter\setter method: CODESNIPPET JAVA4 .
  • If you have a java model of the JSON object you are expecting then you could replace the String parameter with that in your doSomething declaration, such as @RequestBody If you don't have a Java object that matches the JSON then you could try to get it working by replacing the InputStream type with a Reader and see if that gets you closer to a working solution .
  • Edit: I noticed that Spring MappingJacksonJsonMarshaller adds the wrapping class when marshalling, so I stepped through the code in debug and noticed that Spring passes in a HashMap with a single key value pair such that the key is the wrapping name and the value is the object .
  • As suggested here: json with mvc Spring 3 JSON with MVC checkout this website: : spring json sourceforge net It has perfectly nice working example on how to do this in spring framework .
  • Now the issue: As soon as I run it in Spring framework I can write to standard out the entire file content that I have run via the stand alone code .
  • I have just started using Jackson because of the integration with the Spring Framework and have run into an issue with single quotes in a value .
  • I'm pretty sure you only have to register mework http converter json MappingJacksonHttpMessageConverter html @ResponseBody (the easiest way to do that reference html mvc html#mvc config enable is through <mvc:annotation-driven /> in XML or @EnableWebMvc in Java ) See: this forum post and 7 6 5 Configuring Formatting in Spring MVC Here's a working example: Maven POM** CODESNIPPET JAVA1 .

  • Can anyone please tell me what is the "standard" or "easiest" way to use @RequestBody with JSON request data and make that bind to an existing @ModelAttribute populated Command object so that the Command object fully constituted with both old and new data (in the same way it is easily achieved using a full POST http submit) .
  • One change that I can think of is not having the class name in xml, that does not look clean, instead you an try put this information in a custom annotation and use that annotation along with a HandlerMethodArgumentResolver]( javadoc api org springframework web method support HandlerMethodArgumentResolver html) to create the appropriate JavaType and do the unmarshalling there .
  • Im developing web application using springMVC 3 2 6 and Hibernate 3 3 1 when I mapped a spring URL pattern as *.htm and request a URL is getname.htm the method is working fine as checked in debug mode and system.out.println but the JSON is not generated and the output shows as The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers () .
  • The flow is that when receive a call to entry html, it will check and choose to redirect to /logout.jsp handled by spring security and then redirect to /postLogout.html response JSON resolve to view entry , which is a jsp contain only a json string I would like to know if I can use @ResponseBody in getEntry() without using an jsp to write just a json value?.
  • The behavior of this method is quite clear for me: This method handles HTTP GET Request towards the URL " mapping produces" and the produces element specifies that the method will not accept requests with the header named Accept incompatible with the specified MediaType and that this method produces a new object having JSON format that is put in the body field of the HTTP Response * The new JavaBean object contatin only two inizialized variables and getter\setter method: CODESNIPPET JAVA4 .
  • If you have a java model of the JSON object you are expecting then you could replace the String parameter with that in your doSomething declaration, such as @RequestBody If you don't have a Java object that matches the JSON then you could try to get it working by replacing the InputStream type with a Reader and see if that gets you closer to a working solution .
  • To be complete honest, I don't find the Spring integration all that compelling, which isn't really a big deal Much like Spring MVC versus Struts, I'm not really expecting a lot of change with the Spring Rest JSON functionality, I'm just trying to figure out if it actually exists so I can try it out .
  • I call load() function on load it triggers the function getGroups() and returns the list successfully but the problem is once the getGroups() is finished function(data) doesn't load never gets into that function and the error is org springframework web HttpMediaTypeNotAcceptableException: Could not find acceptable representation Can't I post back List does it have to be java primitive type?.
  • I am not strongly attached to the concept of using a 400 for the JSON request or using a separate validator as opposed to a Custom Bean with validation annotation (How do you do that for a JSON request?)
  • Getting this error: CODESNIPPET JAVA4 .
  • Error: CODESNIPPET JAVA4 .
  • I am trying to get a method in springmvc to accept a partial json string of an object, and have jackson automatically de serialize it for me I can solve it by making a temporary object with only the attributes I want, or pass it in as a string and use Gson to desearialize it for me, but these feel hacky .
  • In the Chrome I get 404 Not found error and in Tomcat I get the following error: CODESNIPPET JAVA4 .
  • I'm not sure, the path of my form submission; and there obviously is no JSP view for it, I'm expecting JSON to be returned actually, but for some reason this isn't working, it's just trying to forward me to some JSP, so I'm guessing that I need to specify how to handle this in my XML but I've seen about 1000 different ways that people return JSON, and all of them are very confusing to me, I'm just looking for the simplest way, so I can take it from there edit: I added an answer which is a good start, but it allows you to type " json" after any URL and it will do some really bad things if as the controller I'm not expecting it, so I need to somehow have this view resolver only apply to secured URLs .
  • Json error in Spring .
  • You have to create your own ObjectMapper class and tell Spring to use your custom OM instead of default one .
  • The problem with this solution is that it is not REST compliant .
  • The XML response is valid, however, when the client sets the Accept header to application json, the response is invalid JSON .
  • This function only execute an AJAX call and wait for an HTTP Response passing its content to an handler that will show the output in the view ok Before sending the request, the function check if the URL don't end with json extension** If this request don't end with json extension** the following header is added to my HTTP Request: Accept application json** From what I know the Accept Header say which specific mediatype is considerable acceptable for the HTTP Response, in this case say that the only acceptable media type is a JavaScript object having JSON format, ok .

  • This error happens when the jackson engine tries to parse the json response from the server I am using Spring Android to serialise deserialise objects to and from json This problem seems to be related to the default encoding UTF 8 .

  • Edit: This isn't about URLs that aren't mapped giving exceptions, It's about real URL's with " json" after it that are mapped trying to render their contents as JSON when that isn't what is needed I'm not worried about the exception I'm getting, it makes sense that I'm getting it, I'm saying that some URL's, in fact MOST URLs shouldn't be able to be taken as JSON, and putting " json" after it should just return a 404 .
  • I'm trying to use a Json View for Spring ( json sourceforge net ) (org springframework web servlet view json JsonView) but whenever I write a controller class that extends setApplicationContext I get the following Error: java lang IllegalStateException: ApplicationObjectSupport instance org springframework web servlet view json JsonView does not run in an ApplicationContext The weird thing is, that when I implement the Controller interface directly and do not inherit, it is fine .
  • I would at this time remove the setters (I don't know if you have any spring magic that could cause weirdness), move the User creation into a prepare method and verify that the users are not null (see ) and this is just personal preference but @JSON(name="user") when applied to getUser is redundant so I would get rid of the @JSON annotations on the getters .

      • This is valid JSON and you can see integers and doubles are appearing just fine.. details
      • Yes, probably a best practice, but as I wrote my objects are already JSON strings and I just want to write them out with the correct mime type.. details
      • I've been in the same position as you - looking through the Spring docs for how to implement a simple JSON client API.. details
      • JSON seem to be a lightweight and effective message container for us.. details
      • I know many frameworks (like Spring) can map and serialize data based on the content type, but in general I find that this process is easy enough that it isn't a compelling reason to use application/json over text/plain for JSON objects.. details
      • It's perfectly fine for JSON and it is been displayed as UTF-8.. details
      • I've never worked with Spring, but if it's doing the JSON encoding, this is probably taken care of properly, for you.. details

      • I want to make spring MVC 3.0.3 portlet using DispatcherPortlet class With JSON support.. details
      • I googled around and find a link stating that this bean with JSON only works with servlets in the latest spring vesion.. details
      • This includes support for generating JSON responses and binding JSON requests using the Spring MVC @Controller programming model.. details
      • Since spring-mvc 3.0 official support for Ajax remoting with JSON is provided as part of Spring MVC.. details
      • The best case would be if there was an annotation that I could add to the Controller classes that would turn them into JSON service calls.. details
      • To be complete honest, I don't find the Spring integration all that compelling, which isn't really a big deal.Much like Spring MVC versus Struts, I'm not really expecting a lot of change with the Spring Rest JSON functionality, I'm just trying to figure out if it actually exists so I can try it out.. details
    24. html: 1
      • The id and the project name should be returned to the frontend system, so I can build a HTML ul/li list in this kind: CODESNIPPET_JAVA4 .. details
    25. split: 1
      • Another solution would be to split "MyEntity" into multiple resources and just update these resources, but I feel like it does not make sense: "MyEntity" is a plain resource, it is not composed of** other resources.. details

    31. string: 7
      • Also if you look inside the source code for org.springframework.amqp.core.Message you'll find a method with signature private String getBodyContentAsString() which does it like this: return new String(body, ENCODING); ... therefore this should suffice as well: System.out.println(new String(message.getBody(), Charset.defaultCharset().name())).. details
      • A simple workaround would be to create by hand the string you want to post as a body : CODESNIPPET_JAVA1 .. details
      • Either you know you use only non primitive types, or some rules (empty String is CODETERM4 , which does not work for everyone) or you have to provide an additional parameter which defines the overridden values.. details
      • Sometimes, I just want to update the boolean value, and I don't think that sending the whole object with its big string is a good idea just to update a simple boolean.. details
      • What I really want is two separate Strings (or a String and an int whichever is suitable for the particular request) with just the two values (other key / value pairs that the client may send should be ignored).. details
      • Where JsonObject is simple class with three String atributes (value,id,label).. details

      • I'm new to Spring MVC and was having a really hard time figuring out how to return JSON.. details
      • You have to create your own ObjectMapper class and tell Spring to use your custom OM instead of default one.. details

      • Since property editors are a thing of the past as far as Spring is concerned, we are expected to use the new Conversion Service API.. details
      • You will usually see this type of error when Spring MVC finds a request mapping that matches the URL path but the parameters (or headers or something) don't match what the handler method is expecting.. details
