Question

数据库取出来的Timestamp和获取系统当前时间转成Timestamp类型比较大小，如补充：

SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Timestamp tp=new Timestamp(System.currentTimeMillis());
Calendar rightNow = Calendar.getInstance();
rightNow.setTime(tp);
String tp2=sdf.format(rightNow.getTime()) ;
Timestamp reStr = null;
try {
reStr = new Timestamp(sdf.parse(tp2).getTime());
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Timestamp shixiaodate=personInfoPromotions.get(0).getTopExpirationDate();

if(shixiaodate>reStr){//这句报错

}

Answer 1

改陵罩档闷老成
shixiaodate.compareTo(reStr) > 0

或者用 Timestamp 特有的 after/before 方法尺乱
