java - 日期与纳米时间戳

Question

我想将日期转换为时间戳以设置变量。我有以下代码，但似乎无效。

Date org_last_upd_ts=xxxxxxx;

SimpleDateFormat sdf=new SimpleDateFormat("SSSSSS");
Timestamp org_lastupdts=new Timestamp(org_last_upd_ts.getTime());
org_lastupdts.setNanos(Integer.valueOf(sdf.parse(o rg_last_upd_ts.toLocaleString()).toString()));

知道怎么做吗？

Answer 1

你可以这样转换

java.util.Date now = new Date();
java.sql.Timestamp timestamp = new Timestamp(now.getTime());

来自 javadoc Timestamp constructor

Constructs a Timestamp object using a milliseconds time value. The integral seconds are stored in the underlying date value; the fractional seconds are stored in the nanos field of the Timestamp object.
