Springboot校验集合是否为空，校验集合内对象参数

一、示例1
public AjaxResult saveQuoted(@RequestBody @NotEmpty List< @Valid HisParam> list) {}

二、示例2

public class Comment {
    @NotNull(message = "orderId 不能为空")
    private Long  orderId;
    @Valid
    @NotEmpty(message = "itemList不能为空")
    private List<CommentDetailItem> itemList;

}
