当插入数据包括SpringBoot中的字段dateofbirning类型LocalDate时出现错误java.time.LocalDate

Question

我需要支持以下错误：

这是UserEntity类

@Entity
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class User extends BaseEntity {
    @Column(nullable = false, unique = true, columnDefinition = "varchar(50)")
    private String userName;

    @Column(nullable = false)
    private String password;

    @Column(unique = true, nullable = false)
    private String email;

    @Column(unique = true, nullable = false)
    private String phone;

    @Column
    private String address;

    @Column
    private String fullName;

    @Column
    private LocalDate dateOfBirth;

    @ManyToMany
    @JoinTable(name = "permission",
    joinColumns = @JoinColumn(name = "user_id", nullable = false),
    inverseJoinColumns = @JoinColumn(name = "role_id", nullable = false))
    @JsonIgnore
    private Set<Role> roles = new HashSet<>();

    @OneToMany(mappedBy = "user", fetch = FetchType.LAZY)
    @JsonIgnore
    private List<Blog> blogs = new ArrayList<>();
}

这是UserSaveRequest类

@Getter
@Setter
public class UserSaveRequest {
    private long id;
    private String userName;
    private String password;
    private String email;
    private String phone;
    private String address;
    private String fullName;
    private LocalDate dateOfBirth;
    private List<Long> ids;
}

public User mapToEntity(UserSaveRequest userSaveRequest){
        UserValidate.validate(userSaveRequest);
        String encode = PasswordHasher.hash(userSaveRequest.getPassword());
        User user = new User();
        BeanUtils.refine(userSaveRequest,user,BeanUtils::copyNonNull);
        user.setPassword(encode);
        List<Role> roles = roleRepository.findAllByIdIn(userSaveRequest.getIds());
        user.setRoles(new HashSet<>(roles));

        return user;
    }

@RestController // để đánh dấu là API
@RequestMapping("/api")
@Data
public class UserController extends BaseController {

    private final static Logger LOGGER = LoggerFactory.getLogger(UserController.class);

    private final UserService userService;
    private final UserMapper userMapper;
    private final TokenProducer tokenProducer;

    private JwtPayload createPayload(User user){
        JwtPayload jwtPayload = new JwtPayload();
        jwtPayload.setUserName(user.getUserName());
        jwtPayload.setId(user.getId());
        String roles = user.getRoles().stream().map(Role::getName).collect(Collectors.joining(","));

        jwtPayload.setRole(roles);

        return jwtPayload;
    }

    @PostMapping("/user")
    @PreAuthorize("hashAnyRole('ADMIN') OR hashAnyRole('USER') OR hashAnyRole('MANAGER')")
    public ResponseEntity<BaseResponse> save(@RequestBody UserSaveRequest userSaveRequest) {
        userService.save(userSaveRequest, userMapper::mapToEntity);

        return success();
    }
}

public interface BaseService<T, ID>{
    <RQ> void save(RQ req, Function<RQ, T> transform);
}

@Data
public abstract class AbstractServiceImpl<T, ID> implements BaseService<T, ID> {

    protected final BaseRepository baseRepository;

    public AbstractServiceImpl(BaseRepository baseRepository){
        this.baseRepository = baseRepository;
    }

    @Override
    public <RQ> void save(RQ req, Function<RQ, T> transform) {
        T t = transform.apply(req);
        baseRepository.save(t);
    }
}

@Service
public class UserServiceImpl extends AbstractServiceImpl<User, Long> implements UserService {

    public UserServiceImpl(UserRepository userRepository){
        super(userRepository);
    }
}

Answer 1

此异常是由于jackson不能正常工作，要么是因为它不在您的依赖项中，要么是因为您使用的版本与LocalDate对象不兼容。另一种可能是日期格式2

1*将以下代码添加到pom.xml中：

<dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
</dependency>

2*可以向dateOfborning变量添加格式注释：
