1.在实体类里面加数据，

固定的不用改
public  static class Caopty  implements Comparator{
    @Override
public int compare(Object object1, Object object2) {
        Accept a1 = (Accept) object1;
        Accept a2 = (Accept) object2;
        return a2.getUpdate_time().compareTo(a1.getUpdate_time());
    }
}

2.在ctroller 调用

Comparator
