java.sql.Timestamp 类的使用

java.sql.Timestamp 类的使用

获取当前时间：第一种：Timestamp nowdate1 = new Timestamp(System.currentTimeMillis());System.out.println("System.currentTimeMillis():"+nowdate1);第二种：Date date = new Date();Timestamp nowdate2 = new Timestamp(date.getTime());System.out.println("new Date():"+nowdate2)

把String类型转换Timestamp：String datestr = "2002-01-29 04:37:21.453";Timestamp ts = Timestamp.valueOf(datestr);System.out.println(ts);

把Timestamp 类型转换String：SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");Timestamp nowdate = new Timestamp(System.currentTimeMillis());String datestr = sdf.format(nowdate);System.out.println(datestr);
