I'm doing an integration test against a REST controller POST handler. Well, I'm trying to.
It gives me the HttpMessageNotReadableException exception: Could not read JSON: No content to map due to end-of-input
Here is my controller:
@Controller @RequestMapping("admin") public class AdminController { private static Logger logger = LoggerFactory.getLogger(AdminController.class); private static final String TEMPLATE = "Hello, %s!"; @Autowired private AdminService adminService; @Autowired private AdminRepository adminRepository; @RequestMapping(value = "crud", method = RequestMethod.POST, produces = "application/json; charset=utf-8") @ResponseBody public ResponseEntity<Admin> add(@RequestBody Admin admin, UriComponentsBuilder builder) { AdminCreatedEvent adminCreatedEvent = adminService.add(new CreateAdminEvent(admin.toEventAdmin())); Admin createdAdmin = Admin.fromEventAdmin(adminCreatedEvent.getEventAdmin()); HttpHeaders responseHeaders = new HttpHeaders(); responseHeaders.add("Content-Type", "application/json; charset=utf-8"); responseHeaders.setLocation(builder.path("/admin/{id}").buildAndExpand(adminCreatedEvent.getAdminId()).toUri()); return new ResponseEntity<Admin>(createdAdmin, responseHeaders, HttpStatus.CREATED); } @ExceptionHandler(HttpMessageNotReadableException.class) @ResponseBody public String handleException(HttpMessageNotReadableException e) { return e.getMessage(); } } The base test class:
@RunWith(SpringJUnit4ClassRunner.class) @WebAppConfiguration @ContextConfiguration( classes = { ApplicationConfiguration.class, WebSecurityConfig.class, WebConfiguration.class, WebTestConfiguration.class }) @Transactional public abstract class AbstractControllerTest { @Autowired private WebApplicationContext webApplicationContext; @Autowired private FilterChainProxy springSecurityFilterChain; protected MockHttpSession session; protected MockHttpServletRequest request; protected MockMvc mockMvc; @Before public void setup() { this.mockMvc = MockMvcBuilders.webAppContextSetup(this.webApplicationContext).addFilters(this.springSecurityFilterChain).build(); } } The integration test:
@Test public void testAdd() throws Exception { HttpHeaders httpHeaders = Common.createAuthenticationHeaders("stephane" + ":" + "mypassword"); this.mockMvc.perform( post("/admin/crud").headers(httpHeaders) .param("firstname", "Stephane") .param("lastname", "Eybert") .param("login", "stephane") .param("password", "toto") ).andDo(print()) .andExpect( status().isOk() ).andReturn(); } What the console log has to say:
