1、下载界面包mysql-connector-java-5.0.8-bin.jar 下载链接
2、程序
（1）载入驱动
（2）编程连接操作
（3）返回结果处理
编程演示样例
import java.sql.*;
public class Access2Database{
public Connection getConn(){
Connection conn=null;
try{
Class.forName("com.mysql.jdbc.Driver");

conn=DriverManager.getConnection(url, user, password);
if(conn!=null){
System.out.println("The connection to database is successful!");
}
}catch(Exception e){
e.printStackTrace();
}
return conn;
}
public ResultSet getResultSet(Statement stam,String sql){
ResultSet res=null;
try {
res=stam.executeQuery(sql);
} catch (SQLException e){
e.printStackTrace();
}
return res;
}
void showResultSet(ResultSet res){}
}
import java.sql.*;

代码可以按需要调整
