Java实现用户登录/注册界面(连接Mysql数据库)并可以通过验证码登录

1 效果展示

(1)登录界面

在这里插入图片描述

(2)注册界面

在这里插入图片描述

(3)动图展示

在这里插入图片描述

2 内容说明

(1)开发前,需引入一个连接Mysql 数据库驱动mysql-connector-java-5.1.30-bin.jar包 提取码:6666 (2)构建路径

在这里插入图片描述

(3)需要下载xampp软件 xampp软件下载 提取码:2255

xampp软件包含Apache Web服务器、Mysql Web服务器、Filezilla Web服务器、Mercury服务器以及Tomcat Web服务器。在本项目中,我们只需要开启Apache服务器和Mysql服务器即可。
