试图获取所有用户时，java错误请求400。Dto和表格

Question

我有RESTAPI和用户模型DTO以及创建/更新表单。My userService检查用户是否为管理员，然后允许在列表中获取用户。当我想要获得所有用户时，我得到了错误的请求400，但它应该返回禁止。它过去是可以工作的，但当我在代码中添加一些更改时，我收到了错误的请求。我不知道我错过了什么

我的用户。爪哇

///Lombok annotations
@EqualsAndHashCode(onlyExplicitlyIncluded = true)
@Table(name = "users")
public class User {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Setter(AccessLevel.NONE)
    @Column(unique = true)
    private Long id;

    @Setter(AccessLevel.NONE)
    @EqualsAndHashCode.Include
    @Column(nullable = false, unique = true)
    private UUID uuid = UUID.randomUUID();

    @Column(unique = true, nullable = false, length = 254)
    private String login;
    @Column(nullable = false, length = 254)
    private String firstName;
    @Column(nullable = false, length = 254)
    private String lastName;
    @Enumerated(EnumType.STRING)
    private RoleType roleType;
    @Column(nullable = false, length = 254)
    private String password;
    @Email
    @Column(nullable = false, length = 254)
    private String email;
    @Positive
    private Double cost;

    public User(String login, String firstName, String lastName, RoleType roleType, String password,
                String email, Double cost) {
        this.login = login;
        this.firstName = firstName;
        this.lastName = lastName;
        this.roleType = roleType;
        this.password = password;
        this.email = email;
        this.cost = cost;
    }

用户控制器

@GetMapping("users")
    public ResponseEntity<List<UserDto>> getAllUsers(@RequestParam UUID uuid) {
        return userService.getListResponseEntity(uuid);
    }

用户服务

public ResponseEntity<List<UserDto>> getListResponseEntity(UUID adminUuid) {
        if (authService.adminAuth(adminUuid)) {
            List<User> users = userRepo.findAll();
            List<UserDto> userDto = users
                    .stream()
                    .map(user -> userMapper.mapToUserDto(user))
                    .collect(Collectors.toList());

            return new ResponseEntity<>(userDto, HttpStatus.OK);
        } else {
            return new ResponseEntity<>(HttpStatus.FORBIDDEN);
        }
    }

用户数据

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class UserDto {

    private String login;
    private String firstName;
    private String lastName;
    private RoleType roleType;
    private String email;
    private Double cost;

Answer 1

我认为您在请求头中遗漏了uuid参数。 会是这样的http://localhost:8080/users?uuid="enter_your_uuid_here"

Answer 2

可能存在JSON请求数据与DTO数据字段不匹配的更改。 验证JSON请求中的以下几点

• 可能存在字段名称错误的问题
• 可能没有按照数据类型发送正确的数据
