这是一个标准的Java连接MYsql数据库的步骤，楼主写的几乎是不能用的，一个标准的连接是要关闭资源........由于没有找到合适的源码，所以就找了这个这个日期处理的源码贴上来。
package JDBC;

import java.sql.Connection;
import java.sql.Date;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.DriverManager;
import java.sql.Statement;
import java.sql.Time;
import java.sql.Timestamp;
import java.text.SimpleDateFormat;
import java.util.Calendar;
/**

public class TestJDBCDate {
public static void main(String[] args) {
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
try {
Class.forName("com.mysql.jdbc.Driver");
// new com.mysql.jdbc.Driver();
con = DriverManager.getConnection("jdbc:mysql://localhost:3307/test", "root", "admini");
stmt = con.createStatement();
rs = stmt.executeQuery("SELECT * FROM time");
while(rs.next()) {
/*
Date d = rs.getDate("date");
// SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日");
System.out.println(sdf.format(d));
*/

/*
Time t = rs.getTime("time");
SimpleDateFormat sdf = new SimpleDateFormat("HH时mm分ss秒");
System.out.println(sdf.format(t));
*/

Date d = rs.getDate("datetime");
Time t = rs.getTime("datetime");
SimpleDateFormat sdfdate = new SimpleDateFormat("yyyy年MM月dd日");
SimpleDateFormat sdftime = new SimpleDateFormat("HH时mm分ss秒");
System.out.println(sdfdate.format(d) + sdftime.format(t));

/*
Timestamp dt = rs.getTimestamp("datetime");
SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日HH时mm分ss秒");
System.out.println(sdf.format(dt));
*/

//得到日期中的月
/*
Calendar c = Calendar.getInstance();
c.setTime(d);
System.out.println(c.get(Calendar.MONTH));
*/
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} finally {
try {
if(rs != null) {
rs.close();
rs = null;
}
if(stmt != null) {
stmt.close();
stmt = null;
}
if(con != null) {
con.close();
con = null;
}
} catch (SQLException e) {
e.printStackTrace();
}
}
}
