How to test POST spring mvc - spring-mvc

Question

My problem is to how to call this. I could do
MyObject o = new MyObject();
myController.save(o, "value");
but this is not what I would like to do. I would like the MyObject to be in the request post body? How can this be done?
#Requestmapping(value="/save/{value}", method=RequestMethod.POST)
public void post(#Valid MyObject o, #PathVariable String value{
objectService.save(o);
}
Just to be clear I am talking about unit testing.
Edit:
#RequestMapping(value = "/", method = RequestMethod.POST)
public View postUser(ModelMap data, #Valid Profile profile, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return dummyDataView;
}
data.put(DummyDataView.DATA_TO_SEND, "users/user-1.json");
profileService.save(profile);
return dummyDataView;
}

See sample code below that demonstrates unit testing a controller using junit and spring-test.
#RunWith(SpringJUnit4ClassRunner.class)
#TestExecutionListeners({
DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionalTestExecutionListener.class })
#Transactional
#ContextConfiguration(locations = {
"classpath:rest.xml"
})
public class ControllerTest{
private MockHttpServletRequest request;
private MockHttpServletResponse response;
#Autowired
private RequestMappingHandlerAdapter handlerAdapter;
#Autowired
private RequestMappingHandlerMapping handlerMapping;
#Before
public void setUp() throws Exception
{
this.request = new MockHttpServletRequest();
request.setContentType("application/json");
this.response = new MockHttpServletResponse();
}
#Test
public void testPost(){
request.setMethod("POST");
request.setRequestURI("/save/test"); //replace test with any value
final ModelAndView mav;
Object handler;
try{
MyObject o = new MyObject();
//set values
//Assuming the controller consumes json
ObjectMapper mapper = new ObjectMapper();
//set o converted as JSON to the request body
//request.setContent(mapper.writeValueAsString(o).getBytes());
request.setAttribute("attribute_name", o); //in case you are trying to set a model attribute.
handler = handlerMapping.getHandler(request).getHandler();
mav = handlerAdapter.handle(request, response, handler);
Assert.assertEquals(200, response.getStatus());
//Assert other conditions.
}
catch (Exception e)
{
}
}
}

You need to use RequestBody:
#Requestmapping(value="/save/{value}", method=RequestMethod.POST)
public void post(#RequestBody MyObject o, #PathVariable String value{
objectService.save(o);
}
