You can just let your method return the JSON String if you use the @ResponseBody annotation and use one of the methods listed in the answers to my previous question:

In Spring MVC, how can I set the mime type header when using @ResponseBody

  • Sean Patrick Floyd :I saw your solution how can i do samething without annotations. – user581805 Jan 24 '11 at 12:11
  • Very excellent solution,i will try this solution without annotations – user581805 Jan 24 '11 at 12:55
  • Sean Patrick Floyd :i didn't see CharacterStreams,MediaType classes in Spring 2.5,do i need to download any jars to implement your solution. – user581805 Jan 24 '11 at 16:16
  • No, my guess is that these types have been added in Spring 3.x. (I've never tried MVC in 2.5) – Sean Patrick Floyd Jan 24 '11 at 16:19
  • 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. – user581805 Jan 24 '11 at 17:13
  • Oh, you mean my own solution, sorry. Yes, of course, it just gets more verbose. `CharStreams.copy(CharStreams.newReaderSupplier(json), writer)` creates a `StringReader` from a String and copies all of it's characters to a `PrintWriter`. `Closeables.closeQuietly(writer)` is just a shortcut for calling close() on the writer and wrapping that in a try/catch/finally block. So yes, you can do all of that in plain Java. – Sean Patrick Floyd Jan 24 '11 at 17:18

I'm a total newbie but I've read some where that when you dont specify any logical view mapping for a controller and you return a model map from a handler method (@Controller, @RequestMapping) it should transform the model object to json and return it.
