2、下载jdbc:http://www.mysql.com/products/connector/；

3、将mysql-connector-java-5.1.7-bin.jar包拷贝到jdk的安装路径中的lib包中；

4、new一个Dynamic web工程；

5、项目名称右键单击选择Build Path->Configure Build Path,在弹出的窗口选择Libraries->Add External JAR,然后选择mysql-connector-java-5.1.7-bin.jar，点击ok；

6、接下来就可以测试数据库是否可以连接成功了。

import java.sql.*;  public class Sql {    public static void main(String args[]) {      try {        Class.forName("com.mysql.jdbc.Driver");     //加载MYSQL JDBC驱动程序           //Class.forName("org.gjt.mm.mysql.Driver");       System.out.println("Success loading Mysql Driver!");      }      catch (Exception e) {        System.out.print("Error loading Mysql Driver!");        e.printStackTrace();      }      try {        Connection connect = DriverManager.getConnection(            "jdbc:mysql://localhost:3306/test","root","123456");             //连接URL为   jdbc:mysql//服务器地址/数据库名  ，后面的2个参数分别是登陆用户名和密码          System.out.println("Success connect Mysql server!");        Statement stmt = connect.createStatement();        ResultSet rs = stmt.executeQuery("select * from test");                                                                //user 为你表的名称        while (rs.next()) {          System.out.println(rs.getString("name"));        }      }      catch (Exception e) {        System.out.print("get data error!");        e.printStackTrace();      }    }  }
