Timestamp和String的相互转换

 Timestamp转化为String:

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//定义格式，不显示毫秒

Timestamp now = new Timestamp(System.currentTimeMillis());//获取系统当前时间

String str = df.format(now);

 

      String转化为Timestamp:

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String time = df.format(new Date());

Timestamp ts = Timestamp.valueOf(time);
