List根据时间字符串排序

Collections.sort(resList, new Comparator<LoanApplyLogRes>() {
@Override
public int compare(LoanApplyLogRes o1, LoanApplyLogRes o2) {
SimpleDateFormat format = new SimpleDateFormat(DateUtil.DATE_TIME_FORMAT);
try {
Date dt1 = format.parse(o1.getOperateTime());
Date dt2 = format.parse(o2.getOperateTime());
if (dt1.getTime() > dt2.getTime()) {
return 1;
} else if (dt1.getTime() < dt2.getTime()) {
return -1;
} else {
return 0;
}
} catch (Exception e) {
e.printStackTrace();
}
return 0;
}
});

// 反转集合
Collections.reverse(listSetEntity);

注：默认为升序。反转集合 就是降序
