网上找到好多方法，但是貌似都是不准确，当我看到这个我内牛满面

Timestamp d= new Timestamp(System.currentTimeMillis());

//获取系统时间直接转换成yy--mm-dd HH:mm:ss 形式

下面是一个例子

package com.test.jdbc;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.PreparedStatement;

import java.sql.ResultSet;

import java.sql.Timestamp;

public class Connect {

private static final String DRIVER = "com.mysql.jdbc.Driver";

private static final String IP = "jdbc:mysql://127.0.0.1:3306/msdn";

private static final String user = "root";

private static final String password = "";

public static void main(String args[]) throws Exception {

Connection conn = null;

PreparedStatement pstmt = null;

Timestamp d = new Timestamp(System.currentTimeMillis());

String sql = "insert into user(name,password,age,sex,birthday) values(?,?,?,?,?) ";

Class.forName(DRIVER);

conn = DriverManager.getConnection(IP, user, password);

pstmt = conn.prepareStatement(sql);

pstmt.setString(1, "zl");

pstmt.setString(2, "123456");

pstmt.setInt(3, 24);

pstmt.setString(4, "man");

pstmt.setTimestamp(5, d);

pstmt.executeUpdate();

pstmt.close();

conn.close();

}

}
