@Valid 校验嵌套对象
参考网上的博客：ValidList 能校验list。
通过测试发现，@Valid只能校验一层。比如我这里有个person对象，里面有个ValidList<Teacher> 属性，Teacher对象里面有个List<Student> 属性。
如果在Controller层加上@Valid 是校验不到ValidList<Student> 属性的。
需要在List<Teacher> 属性前面加上 List<@Valid Teacher>
沾点代码：

@PostMapping ( "/test" ) public String testBytes( @Valid @RequestBody ValidList<Persion> persions){ return "success" ; }
@Data public class Persion { @NotNull (message = "name != null" ) private String name; @NotNull (message = "teacherList != null" ) private ValidList< @Valid Teacher> teacherList; }
@Data public class Teacher { @NotNull private String name; @NotNull private List<Student> students; } |
@Valid 嵌套对象验证不成功
controller：
|
1 2 3 4 5 |
@PostMapping ( "WSendList" ) public ApiResult getList( @ApiParam (required = true ) @Valid @RequestBody PageListIO<WSendIO> body) { ... return ApiResult.success(); } |
PageListIO对象：
WSendIO对象：
|
1 2 3 4 5 |
public class WSendIO implements Serializable{ @NotNull (message = "字段 不能为空" ) private Integer isTest; ... } |
这样请求WSendIO中的验证时不会执行的
解决方案：在PageListIO中使用@Valid
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
