1、mysql加载数据库driver=com.mysql.jdbc.Driver数据库的链接url=jdbc:mysql://localhost:3306/demo1用户名username=root密码password=123456设置配置文件信息
3、// 获取配置文件中的相关参数值try {读取配置文件properties.load(DBUtil.class.getCl锾攒揉敫assLoader().getResourceAsStream("db.properties"));driver = properties.getProperty("driver"); url=properties.getProperty("url"); username=properties.getProperty("username"); password=properties.getProperty("password");
5、 //连接数据库的方法public static Connection getConnection() throws SQLEx艘早祓胂ception{Connection con=null;con=DriverManager.getConnection(url,username,password);return con;} //关闭数据库的方法public static void closeConnection(Connection con){try {con.close();} catch (SQLException e) {System.out.println("关闭资源失败");}}}
