java连接MySql数据库

import java.sql.*;

public class Link {
public static void main(String[]args)
{
try
{
String url="jdbc:mysql://localhost/test";
String user="root";
String pwd="w111206";

//加载驱动，这一句也可写为：Class.forName("com.mysql.jdbc.Driver");
Class.forName("com.mysql.jdbc.Driver").newInstance();
//建立到MySQL的连接
Connection conn = DriverManager.getConnection(url,user, pwd);

//执行SQL语句
Statement stmt = conn.createStatement();//创建语句对象，用以执行sql语言
ResultSet rs = stmt.executeQuery("select * from teacher");

//处理结果集
while (rs.next())
{
String name = rs.getString("id");
System.out.println(name);
}
rs.close();//关闭数据库
conn.close();
}
catch (Exception ex)
{
System.out.println("Error : " + ex.toString());
}

System.out.print("ss");
}
