Spring MVC Rest / JSON service

I just tried adding this to my sample controller:

@RequestMapping(value="/jsontest", method=RequestMethod.GET)
    public @ResponseBody User getUserAsJson() {

        User jsonUser = new User();
        jsonUser.setFirstName("Mickey");
        jsonUser.setLastName("Mouse");
        jsonUser.setUsername("mmous");


        return jsonUser;
    }

However, visiting the /jsontest url ends on a 406 http error => not acceptable.

So... what's the currently working method for producing "application/json" responses, instead of returning jsp/html views?

I'm using Spring Framework 3.0.6 RELEASE.

@RequestMapping(value="/jsontest", method=RequestMethod.GET,produces="application/json")
    public @ResponseBody User getUserAsJson() {

        User jsonUser = new User();
        jsonUser.setFirstName("Mickey");
        jsonUser.setLastName("Mouse");
        jsonUser.setUsername("mmous");


        return jsonUser;
    }

This should work add produces attribute..

Add Jackson mapper to your CLASSPATH:

<dependency>
   <groupId>org.codehaus.jackson</groupId>
   <artifactId>jackson-mapper-asl</artifactId>
   <version>1.9.2</version>
</dependency>

And call your web service with correct accept header, e.g.:

$ curl -H "Accept: application/json" localhost:8080/app/jsontest

Or using $.getJSON() from browser.
