eclipse导入jar包连接mysql数据库出错，帮帮忙~谢谢

import java.sql.*;

public class MysqlJdbc {

  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","123");

           //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 user");

                                                              //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();

    }

  }
