Estoy tratando de probar mi controlador de descanso. No hay problemas con los GET, pero cuando trato de probar un método POST no puedo adjuntar el cuerpo.

 private static final MediaType contentType = new MediaType(MediaType.APPLICATION_JSON.getType(), MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8")); private ObjectMapper jsonMapper = new ObjectMapper().setSerializationInclusion(JsonInclude.Include.NON_NULL); @Test public void test1() throws Exception { //...Create DTO //...Create same pojo but as entity when(serviceMock.addEntity(e)).thenReturn(e); mvc.perform(post("/uri") .contentType(contentType) .content(jsonMapper.writeValueAsString(dto)) ) .andDo(print()) .andExpect(status().isCreated()) .andExpect(content().contentType(contentType)); //fails because there is no content returned }

Esta es la salida de la solicitud:

 MockHttpServletRequest: HTTP Method = POST Request URI = /uri Parameters = {} Headers = {Content-Type=[application/json;charset=UTF-8]}

No hay nadie. ¿Por qué? jsonMapper.writeValueAsString(dto) y no es nulo.

editar:

Agregar código de controlador:

 @RestController @RequestMapping("/companies") public class CompanyController { @Autowired private CompanyService service; @Autowired private CompanyMapper mapper; @RequestMapping(method=RequestMethod.GET) public List<CompanyDTO> getCompanies() { List<Company> result = service.getCompanies(); return mapper.toDtoL(result); } @RequestMapping(method=RequestMethod.POST) @ResponseStatus(HttpStatus.CREATED) public CompanyDTO createCompany(@RequestBody @Valid CompanyDTO input) { Company inputE = mapper.toEntity(input); Company result = service.addCompany(inputE); return mapper.toDto(result); }
