Spring Boot @Validation @Valid

@Valid是使用hibernate validation的時候使用

@Validated 是只用spring  Validator 校驗機制使用

基於方法參數的校驗對基本類型的校驗

 

例如：以下服務觸發第一個參數的驗證，確保其大小在8到10之間：

@Service
@Validated
public class MyBean {
   public Archive findByCodeAndAuthor(@Size(min = 8, max = 10) String code,
    Author author) {
    ...
   }
}

基於方法參數的校驗對象校驗

@ToString @Data @EqualsAndHashCode public class UserDTO { private Integer id; /** * {@code @NotNull javax.validation 注意引入的包 } */ @NotNull private String account; @NotNull private String name; @NotNull private String sex; @NotNull @Pattern(regexp="^[0-9]{11}$") private String phone; @NotNull @Email private String email; } 

 /**
     * 添加
     * 
     *@Validated必須添加否則只在對象字段上添加不會生效
     * @return ResponseEntity<Void>
     */
    @PostMapping
    public ResponseEntity<Void> save(@Validated  @RequestBody  UserDTO userDTO) {
        userService.insert(userDTO);
        return ResponseEntity.ok().build();
    }
