数据库连接用的是jdbc-odbc桥,url="jdbc:odbc:user_db"; 不管用什么数据库,只要配置好数据源名字:user_db就可以
表是message(title char(50),name char(16),email char(30),datetime char(20),content varchar(500)),我用的是db2
在不同的数据库里可能有的地方稍有不同
Connection con=DriverManager.getConnection(url,"insher","insher"); 这一行是连接数据库,用户名:insher密码:insher根据具体情况修改
