利用jsp+mysql实现好看的登录与注册页面(动态背景)

效果图：

需要建立以下五个文件：

在webcontent文件夹下面建立css文件，login.jsp与loginjudge.jsp，registcheck.jsp直接放到webcontent文件夹下面，normalize.min.css与login.css放到css文件里面

数据库我建立的是Td_Snacks，连接数据库账号和密码是root，111，不同的请自己修改代码

建立数据库Td_Snacks

表：user

SET FOREIGN_KEY_CHECKS=0;

— —————————-
— Table structure for users
— —————————-
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
`userid` varchar(20) NOT NULL,
`username` varchar(8) DEFAULT NULL,
`userpwd` varchar(20) DEFAULT NULL,
`useremail` varchar(50) DEFAULT NULL,
`useraddress` char(100) CHARACTER SET utf8 DEFAULT NULL,
`u_profile` varchar(10000) DEFAULT NULL,
PRIMARY KEY (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
