打开xampp 控制面板，启动mysql

把Mysql的执行文件路径添加到PATH环境变量中来

Mysql安装完成

2. 下载mysql的连接jar包：mysql-connector-java-5.1.22-bin.jar

3. 启动mysql后，在命令行中进入mysql的root用户：

mysql -u root

create database db;

use db;create table user(id int, name varchar(20));insert into user(id, name) values (1, 'hello');insert into user(id, name) values(2, 'good');

5. 接着在刚才的工程中新建类Conn，并添加以下代码：

Conn.java:

import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.SQLException;import java.sql.Statement;import com.mysql.jdbc.Connection;public class Conn {	public static void main(String[] args) throws ClassNotFoundException, SQLException{		Class.forName("com.mysql.jdbc.Driver");				Connection conn = (Connection) DriverManager.getConnection("jdbc:mysql://localhost:3306/db",				"root", "");		Statement stmt = conn.createStatement();				ResultSet rs = stmt.executeQuery("select * from user");				while(rs.next()){			System.out.println(rs.getInt(1) + " " + rs.getString(2));		}				if (rs != null)			rs.close();		if (stmt != null)			stmt.close();		if (conn != null)			conn.close();	}}
