Spring Boot @Validation @Valid

@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;
}
Spring Boot @Validation @Valid

 /**
     * 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:
