@Valid是使用hibernate validation的时候使用

@Validated 是只用spring  Validator 校验机制使用

### 基于方法参数的校验对基本类型的校验 ###

例如：以下服务触发第一个参数的验证，确保其大小在8到10之间：

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

## 基于方法参数的校验对象校验 ##

@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必须添加否则只在对象字段上添加不会生效  
     \* @return ResponseEntity<Void>  
     \*/  
    @PostMapping  
    public ResponseEntity<Void> save(@Validated  @RequestBody  UserDTO userDTO) \{  
        userService.insert(userDTO);  
        return ResponseEntity.ok().build();  
    \}

## 嵌套校验： ##
