Spring MVC controller Test - print the result JSON String

Question

Hi I have a Spring mvc controller

@RequestMapping(value = "/jobsdetails/{userId}", method = RequestMethod.GET)
@ResponseBody
public List<Jobs> jobsDetails(@PathVariable Integer userId,HttpServletResponse response) throws IOException {
    try {       
        Map<String, Object> queryParams=new LinkedHashMap<String, Object>(); 

        queryParams.put("userId", userId);

        jobs=jobsService.findByNamedQuery("findJobsByUserId", queryParams);

    } catch(Exception e) {
        logger.debug(e.getMessage());
        response.sendError(HttpServletResponse.SC_BAD_REQUEST);
    }
    return jobs;
}

I want to see how the JSON String will looks like when I run this. I wrote this test case

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration("classpath:webapptest")
@ContextConfiguration(locations = {"classpath:test-applicationcontext.xml"})
public class FindJobsControllerTest {
private MockMvc springMvc;

    @Autowired
    WebApplicationContext wContext;

    @Before
    public void init() throws Exception {
        springMvc = MockMvcBuilders.webAppContextSetup(wContext).build();
    }

    @Test
    public void documentsPollingTest() throws Exception {
        ResultActions resultActions = springMvc.perform(MockMvcRequestBuilders.get("/jobsdetails/2").accept(MediaType.APPLICATION_JSON));

        System.out.println(/* Print the JSON String */); //How ?
    }
}

How to get the JSON string?

I am using Spring 3, codehause Jackson 1.8.4

Try this code:

resultActions.andDo(MockMvcResultHandlers.print());
