问题出在测试UserController中声明的端点时的PUT方法单元测试上，我不知道问题出在哪里。
运行测试时：testUpdateUser（），然后我将得到错误：java.lang.AssertionError: JSON路径"$. name"应为：是"鲍勃"但是是"爱丽丝"
我的单元测试什么是得到一个错误：

@Test
    public void testUpdateUser() throws Exception {
        User user = new User(1, "Alice", "alice", "alice@example.com");
        when(UserDao.getUserById(1)).thenReturn(Collections.singletonList(user)); // Retrieve the user from the mock database
        User updatedUser = new User(1, "Bob", "bob", "bob@example.com");

        when(UserDao.updateUser(updatedUser, 1)).thenReturn(1);
        ; // Update the user in the mock database

        ObjectMapper mapper = new ObjectMapper();
        String json = mapper.writeValueAsString(updatedUser);

        MockHttpServletRequestBuilder requestBuilder = put("/users/1")
                .contentType(MediaType.APPLICATION_JSON)
                .content(json);

        mockMvc.perform(requestBuilder)
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.id", is(1)))
                .andExpect(jsonPath("$.name", is("Bob")))
                .andExpect(jsonPath("$.username", is("bob")))
                .andExpect(jsonPath("$.email", is("bob@example.com")));

        verify(UserDao).updateUser(updatedUser, 1);
        verify(template).convertAndSend("/topic/update", updatedUser);
    }

完整错误：

HTTP Method = PUT
      Request URI = /users/1
       Parameters = {}
          Headers = [Content-Type:"application/json;charset=UTF-8", Content-Length:"64"]
             Body = {"id":1,"name":"Bob","username":"bob","email":"bob@example.com"}
    Session Attrs = {}

Handler:
             Type = com.example.padar.controller.UserController
           Method = com.example.padar.controller.UserController#editUsers(int, User, HttpServletRequest)

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = null

ModelAndView:
        View name = null
             View = null
            Model = null

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 200
    Error message = null
          Headers = [Vary:"Origin", "Access-Control-Request-Method", "Access-Control-Request-Headers", Content-Type:"application/json", Content-Length:"70"]
     Content type = application/json
             Body = {"id":1,"name":"Alice","username":"alice","email":"alice@example.com"}
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

java.lang.AssertionError: JSON path "$.name"
Expected: is "Bob"
     but: was "Alice"

用户控制器：

@PutMapping("/users/{id}")
 
    public ResponseEntity<?> editUsers(@PathVariable int id,@RequestBody User user, @Autowired HttpServletRequest request){

        LOG.info(
                "FINISHED PROCESSING : METHOD={}; REQUESTURL={}; ID={}; REQUESTBODY={}; OLDUSER={};",
                request.getMethod(), request.getRequestURI(), request.getSession().getId(),
                user.toString(), UserDao.getUserById(id).get(0).toString());
            UserDao.updateUser(user, id);
            template.convertAndSend("/topic/update", UserDao.getUserById(id));
            return ResponseEntity.ok(UserDao.getUserById(id).get(0));

    }

用户道：

public class UserDao {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    private static final String SQL_GET_ALL_USERS = "SELECT * FROM user";

    private static final String SQL_GET_USER_BY_ID = "SELECT id,name,username,email FROM user where id = ?";

    private static final String SQL_GET_POSTED_USER = "SELECT id,username,email FROM user ORDER BY id DESC LIMIT 1 ";

    private static final String SQL_DELETE_USER_BY_ID = "DELETE FROM user WHERE id=?";

    private static final String SQL_MAKE_NEW_USER = "INSERT INTO user(name,username,email) VALUES(?,?,?)";

    private static final String SQL_UPDATE_USER = "UPDATE user SET name = ?, username = ?, email = ? WHERE id=?";
    public List<User> getAllUsers() {
        return jdbcTemplate.query(SQL_GET_ALL_USERS, new UserMapper());
    }

    public int deleteUserById(int id) {
        return jdbcTemplate.update(SQL_DELETE_USER_BY_ID, id);
    }

    public List<User> getUserById(int id) {return jdbcTemplate.query(SQL_GET_USER_BY_ID,new UserMapper(),id); }
    public List<User> showPostedUser() {return jdbcTemplate.query(SQL_GET_POSTED_USER,new UserMapper()); }

    public int addUser(User user) {
        jdbcTemplate.update(SQL_MAKE_NEW_USER,
                user.getName(),
                user.getUsername(),
                user.getEmail());
        return 1;
    }

    public int updateUser(User user, int id) {
        return jdbcTemplate.update(SQL_UPDATE_USER,
                user.getName(),
                user.getUsername(),
                user.getEmail(),
                id);
    }
}

因为返回的是user，所以它的名称是 Alice，如果Bob实际上不用于显示，就不能将 Bob 作为输出，对吗？
编写代码以返回user，然后检查updatedUser的属性。
设置Mockito，使其返回正确的对象。
