MockMvc 响应返回 404，预期响应 201

Question

我是在 Spring Boot 中对 REST API 进行单元测试的新手。

我希望响应状态为已创建，但我收到了一个 PAGE NOT FOUND 错误。

下面是代码：-

UserControllerUnitTests

@SpringBootTest
@ContextConfiguration(classes = { CommonConfig.class, SecurityConfig.class})
@RunWith(SpringRunner.class)
class UserControllerUnitTests {

    private static ObjectMapper mapper;
    private static final String URI = "/users";

    MockMvc mvc;

    @Autowired
    WebApplicationContext webAppContext;

    @Mock
    UserService userService;

    MvcResult mvcResult;

    @BeforeAll
    static void setUp() {
        mapper = new ObjectMapper();
    }

    @BeforeEach
    void initialize() throws Exception {
        mvc = MockMvcBuilders.webAppContextSetup(webAppContext).build();
    ....
    ....
    ....
   
    void shouldReturnStatusCreatedIfValidUserPassedForPostUser(long index) throws Exception {
        int expectedStatus = HttpStatus.CREATED.value();
        UserDAO returnUser;
    
        UserDAO user = userList.get(index);
        userList.remove(index);
        String jsonContent = mapper.writeValueAsString(user);
    
        user.setId(index);
        user.setEncryptedPassword(null);
    
        Mockito.when(userService.addUser(Mockito.any())).thenReturn(user);
    
        mvcResult = mvc.perform(MockMvcRequestBuilders.post(URI)
            .accept(MediaType.APPLICATION_JSON)
            .contentType(MediaType.APPLICATION_JSON)
            .content(jsonContent)).andReturn();
    
        //Mockito.verify(userService, Mockito.times(1)).addUser(Mockito.any());
    
        int actualStatus = mvcResult.getResponse().getStatus();
        Assert.assertEquals("Response status should be CREATED", expectedStatus, actualStatus);
    
        jsonContent = mvcResult.getResponse().getContentAsString();
        returnUser = mapper.readValue(jsonContent, UserDAO.class);
    
        Assert.assertEquals("EncryptedPassword should not be returned", null, 
                                          returnUser.getEncryptedPassword());
    }

用户控制器类

 @RestController
 @RequestMapping("users/")
 public class UserController {

     UserService userService;
    
     @Autowired
     public UserController(UserService userService) {
         this.userService = userService;
     }
     ....
     ....
     ....

     @PostMapping(path = "",
            consumes = { MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON }, 
            produces = { MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    public ResponseEntity<UserDAO> createUser(@Valid @RequestBody UserDAO user) {
        String password = user.getEncryptedPassword();
        user.setEncryptedPassword(null);
        UserDAO retreivedUser;
    
        if(user.getId() != 0)
            return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
    
        user.setEncryptedPassword(password);
        retreivedUser = userService.addUser(user);
        if(retreivedUser != null)
            return new ResponseEntity<>(retreivedUser, HttpStatus.CREATED);
        return new ResponseEntity<>(HttpStatus.CONFLICT);
    }
}

我发现了一些错误：

1. 摆脱 ContextConfiguration

   @SpringBootTest
   // @ContextConfiguration(classes = { CommonConfig.class, SecurityConfig.class})
   @RunWith(SpringRunner.class)
   class UserControllerUnitTests {
   

2. 在控制器上指定正确的映射（无斜线）

   @RestController
   @RequestMapping("users")
   public class UserController {
   

3. 您设置了未在测试中使用的 UserService 模拟。你是说@MockBean 吗？

   @MockBean
   UserService userService;
