1,首先寫個方法package util;import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;public class DBUtil { static String jdbcURL = "jdbc:mysql://localhost:3306/book";

static String jdbcDriver = "com.mysql.jdbc.Driver";

static String userName = "root";

static String password = "root";

/**

* 獲取資料庫連線物件

* @return 資料庫連線物件

* @throws ClassNotFoundException

* @throws SQLException

*/

public static Connection getConnection() throws ClassNotFoundException,

SQLException {

Class.forName(jdbcDriver);

return DriverManager.getConnection(jdbcURL, userName, password);

}

} 2。專案名==>右鍵==>build path==>add external archivers.... 選擇你mysql驅動 新增進去就ok了
