问题描述
我正在对 REST 控制器 POST 处理程序进行集成测试.嗯，我正在努力.
I'm doing an integration test against a REST controller POST handler. Well, I'm trying to.
它给了我 HttpMessageNotReadableException 异常:无法读取 JSON:由于输入结束，没有要映射的内容
It gives me the HttpMessageNotReadableException exception: Could not read JSON: No content to map due to end-of-input
这是我的控制器:
@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();
}
}
基础测试类:
@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();
}
}
集成测试:
@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();
}

有什么线索吗?
推荐答案
我替换了 .param() 方法以支持 .content() 方法:
I replaced the .param() methods in favor of the .content() one:
post("/admin/crud").headers(httpHeaders)
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON)
.content("{ "firstname" : "" + admin0.getFirstname() + "", "lastname" : "" + admin0.getLastname() + "", "email" : "" + admin0.getEmail() + "", "login" : "" + admin0.getLogin() + "", "password" : "" + admin0.getPassword() + "", "passwordSalt" : "" + admin0.getPasswordSalt() + "" }")
).andDo(print())
.andExpect(status().isCreated())
.andExpect(jsonPath("$.firstname").value(admin0.getFirstname()))
.andExpect(jsonPath("$.lastname").value(admin0.getLastname()))
.andExpect(jsonPath("$.email").value(admin0.getEmail()))
.andExpect(jsonPath("$.login").value(admin0.getLogin()))
.andExpect(jsonPath("$.password").value(admin0.getPassword()))
.andExpect(jsonPath("$.passwordSalt").value(admin0.getPasswordSalt()))
.andReturn();
现在它按预期工作了.
