@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();
}
