javax.validation不会验证列表，仅验证JavaBean。解决方法是使用自定义的List类：
代替
@RequestBody @Valid List<@Valid Foo> request
采用：
@RequestBody @Valid ValidList<@Valid Foo> request
有效清单
public class ValidList<E> implements List<E> { @Valid private List<E> list; public ValidList() { this.list = new ArrayList<E>(); } public ValidList(List<E> list) { this.list = list; } // Bean-like methods, used by javax.validation but ignored by JSON parsing public List<E> getList() { return list; } public void setList(List<E> list) { this.list = list; } // List-like methods, used by JSON parsing but ignored by javax.validation @Override public int size() { return list.size(); } @Override public boolean isEmpty() { return list.isEmpty(); } // Other list methods ...}
