不同的响应代码-内部测试不可接受状态

Question

测试用例有什么问题？？

我有以下代码：

@PreAuthorize("permitAll()")
@RequestMapping(value = "/register", method = RequestMethod.POST, produces = "application/json", consumes = "application/json")
public ModelMap register(@RequestBody @Valid User user, Locale locale, BindingResult result) {
    logger.info("Register");
    logger.info(user.getMail());
    logger.info("usern " + user.getUsername());
    logger.info("Result " + result.hasErrors());
    if (result.hasErrors()) {
        final Set<String> fieldsName = getErrorFieldsName(result);
        throw new RegistrationException(fieldsName);
    }
    if (!isValidateMail(user.getMail()))
        throw new RegistrationException(Collections.singleton("mail"));
    final UUID id = UUID.randomUUID();
    userRepo.saveUser(escapeUser(user, id));
    return new ModelMap("msg", "You are registered correct!");
}

当我通过REST Client调用此控制器时，如：

POST请求标头

User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.152 Safari/537.36

Accept-Language: pl,en;q=0.8,en-US;q=0.6

带机身：

  {
"mail":"alddajdf@mad_kta.com",
"username":"User",
"password":"qwerdty123"
}

我收到带有以下标题的响应代码200：

Server: Wildfly 8 
Transfer-Encoding: chunked 
Content-Type: application/json 
Date: Thu, 10 Apr 2014 16:27:42 GMT 

但内部测试用例：

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("file:src/main/webapp/WEB-INF/mvc-dispatcher-servlet.xml")
public class RegisterAccountContrTest {
@SuppressWarnings("SpringJavaAutowiringInspection")
@Autowired
protected WebApplicationContext wac;
private MockMvc mockMvc;
@InjectMocks
private RegisterAccountContr contr;
@Before
public void init() {
    this.mockMvc = webAppContextSetup(this.wac).build();
    MockitoAnnotations.initMocks(this);
    BasicConfigurator.configure();
}
@Test
public void testRegister() throws Exception {
final String s;
s = "{n" +
        ""mail":"alddajdf@mad_kta.com",n" +
        ""username":"User",n" +
        ""password":"qwerty123"n" +
        "}";
mockMvc.perform(post("/register").contentType(MediaType.APPLICATION_JSON).content(s)).andExpect(status().isOk());
}

生成响应代码：

java.lang.AssertionError: Status 
Expected :200
Actual   :406

Answer 1

如果不指定MockMvcRequestBuilder，我不认为它会隐式添加Accept标头。你应该添加一个

mockMvc.perform(post("/register")
        .accept(MediaType.APPLICATION_JSON)
        .contentType(MediaType.APPLICATION_JSON)
        .content(s))
   .andExpect(status().isOk());

Answer 2

解决方案很简单，我错过了ContentNegotiationManagerFactoryBean所需的.json后缀。正确的url应该是：/register.json
