@validated 验证 List 参数

写了个接口：

@GetMapping("/do")
public int doSth(@RequestBody @Validated(MyGroup.class) List<Bean> myBean)

发现@validated完全没用，但是用@valid可以，但是我要用分组功能必须用@validated，在stackOverflow上找到了解决方案：
https://stackoverflow.com/questions/28150405/validation-of-a-list-of-objects-in-spring

在项目里添加一个ValidList类即可，此类通用，可以在全部由此需求的项目（jdk1.8）中添加，无需改动，有ValidList类之后只要将接口方法参数中的List改成ValidList即可：

@GetMapping("/do")
public int doSth(@RequestBody @Validated(MyGroup.class) ValidList<Bean> myBean)

注意：

• 如果你不用lombok，就把@Data注解去掉，给类中的list成员加上getter，setter方法即可

ValidList：

import lombok.Data;

import javax.validation.Valid;
import java.util.*;

@Data
public class ValidList<E> implements List<E> {

  @Valid
  private List<E> list = new LinkedList<>();

  @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);
  }
}
