@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：
package com.xiaoming.entity;
import javax.validation.Valid;
import java.util.*;
public class ValidList<E> implements List<E> {
@Valid
private List<E> list = new ArrayList<>();
@Override
public int size() {
return list.size();
}
@Override
public boolean isEmpty() {
return list.isEmpty();
}
@Override
public boolean contains(Object o) {
return list.contains(o);
}
@Override
public Iterator<E> iterator() {
return list.iterator();
}
@Override
public Object[] toArray() {
return list.toArray();
}
@Override
public <T> T[] toArray(T[] a) {
return list.toArray(a);
}
@Override
public boolean add(E e) {
return list.add(e);
}
@Override
public boolean remove(Object o) {
return list.remove(o);
}
@Override
public boolean containsAll(Collection<?> c) {
return list.containsAll(c);
}
@Override
public boolean addAll(Collection<? extends E> c) {
return list.addAll(c);
}
@Override
public boolean addAll(int index, Collection<? extends E> c) {
return list.addAll(index, c);
}
@Override
public boolean removeAll(Collection<?> c) {
return list.removeAll(c);
}
@Override
public boolean retainAll(Collection<?> c) {
return list.retainAll(c);
}
@Override
public void clear() {
list.clear();
}
@Override
public E get(int index) {
return list.get(index);
}
@Override
public E set(int index, E element) {
return list.set(index, element);
}
@Override
public void add(int index, E element) {
list.add(index, element);
}
@Override
public E remove(int index) {
return list.remove(index);
}
@Override
public int indexOf(Object o) {
return list.indexOf(o);
}
@Override
public int lastIndexOf(Object o) {
return list.lastIndexOf(o);
}
@Override
public ListIterator<E> listIterator() {
return list.listIterator();
}
@Override
public ListIterator<E> listIterator(int index) {
return list.listIterator(index);
}
@Override
public List<E> subList(int fromIndex, int toIndex) {
return list.subList(fromIndex, toIndex);
}
public List<E> getList() {
return list;
}
public void setList(List<E> list) {
this.list = list;
}
}
@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：
@PostMapping("WSendList")
public ApiResult getList( @ApiParam(required = true) @Valid @RequestBody PageListIO<WSendIO> body) {
...
return ApiResult.success();
}
PageListIO对象：
WSendIO对象：
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编程网。
