【项目分享~写给应届生的一篇文章】基于Web企业招聘网站 ~~ 登录注册设计

背景

适合人群：应届生
推荐：可直接做为毕业设计项目，开发架构简单，按照统一的规范开发，容易上少
原因：这个项目涉及到SSM三大框架，所以刚刚入门JavaWeb的同学可能不大适合，缺少太多必备的知识，导致学习这个项目事倍功半。如果你已经是有一两年工作经验开发者，这个项目对你的level太低了，也不推荐哦
每年的话我都会指导一些应届生过计算机毕业设计，在这个过程中，很多人都会问到以下问题:\color{red}每年的话我都会指导一些应届生过计算机毕业设计，在这个过程中，很多人都会问到以下问题:每年的话我都会指导一些应届生过计算机毕业设计，在这个过程中，很多人都会问到以下问题:
登录注册是如何实现了？
如何实现可以发邮件？
账户激活如何实现？
以“基于Web企业招聘网站”\color{red}“基于Web企业招聘网站”“基于Web企业招聘网站”这篇文章为例，今天给大家讲讲这个：登录注册是如何实现的

小总结

你还在为大学最后的毕业设计而苦恼吗？
你还在面对毕业设计而无从下手吗？
你还在实习，但苦于没有时间做毕业设计吗？
适合应届生当做项目经验、或者毕设作品
小作者的随手之作，实现难度不难~~
这个项目，你值得拥有

登录权限设计

为了方便大家理解，我先把整个过程database->dao->service->controller整个流程的代码先贴出来

表结构设计

最核心的字段： username 和 password ，账号密码，isAudit是用来激活使用的
注册时，isAudit值为1，表示未激活，需要邮件激活后变为2，才可以登录使用

CREATE TABLE `user` (`id` int(11) NOT NULL AUTO_INCREMENT,`username` varchar(20) DEFAULT NULL COMMENT '账号',`password` varchar(100) DEFAULT NULL,`isAudit` int(2) DEFAULT NULL COMMENT '是否审核',`register` datetime DEFAULT NULL COMMENT '注册时间',`qq` varchar(255) DEFAULT NULL COMMENT '关联qq号',`weixin` varchar(255) DEFAULT NULL COMMENT '关联微信号',`other` varchar(255) DEFAULT NULL COMMENT '其他信息',PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=50 DEFAULT CHARSET=utf8;

小解读

注册的方法

用户注册时，手机账号和密码，对密码做md5加密，然后把isAudit设置为1，表示未激活，然后调用邮件的工具类进行发邮件

/*** 用户注册* @throws Exception */@RequestMapping("/register")public @ResponseBody Response insertUser(User user) throws Exception {//1.0 声明需要返回的类型Response rep = new Response();//判断邮箱是否存在User u = userServiceImpl.selectUserByUsername(user.getUsername());if(u!=null) {//返回错误信息，邮箱已存在rep.setCode(-1);rep.setMsg("邮箱已存在，您已经注册过我们网站，请返回登录");return rep;}user.setIsaudit(1);user.setRegister(new Date());String baseString = MyMd5Utils.encodeByMD5(user.getUsername()+"-"+user.getPassword());user.setPassword(baseString);int i = userServiceImpl.insertUser(user);if(i > 0) {rep.setCode(1);rep.setMsg("完美注册,请到您的邮箱上激活，否则不允许登录");//MailUtils11.sendMail("招聘网站提醒", user.getUsername(), "账号激活", "您成功注册了小郑招聘网站，接下来点击下面按钮激活即可<br/>"+"http://localhost:8080/recruitmentWebsite/user/xiaochengxu/jihuo?baseString="+baseString);return rep;}else {rep.setCode(-1);rep.setMsg("程序有问题，请检查你的程序");return rep;}}

【备注】如果不想要有激活的功能，那么把isAudit设置为2或者在登录时，去掉对isAudit的判断即可
如果不能发送邮件，则注释发送邮件的代码即可，发送邮件是一个工具类，后面会分享给大家

登录方法

先用账号和MD5加密后的数据去数据库找到是否有数据
判断isAduit字段，账号是否可以的判断

@RequestMapping("/toLogin")public @ResponseBody Response toLogin(User user,HttpServletRequest  request) {//1.0 声明需要返回的类型Response rep = new Response();//2.0 根据用户名+密码去检索数据库String basePassword = MyMd5Utils.encodeByMD5(user.getUsername()+"-"+user.getPassword());User u = userServiceImpl.selectUserByUsernameAndPassword(user.getUsername(),basePassword);if(u!=null) {//3.0表示登陆成功if(u.getIsaudit() == 2) {//4.0 账号密码错误rep.setCode(-1);rep.setMsg("您的账户已经被冻结，请联系管理员924155240@qq.com");return rep;}else if(u.getIsaudit() == 3){rep.setCode(-1);rep.setMsg("您登录的账户还没有激活，请到注册的邮箱上点击激活按钮");request.getSession().setAttribute("user", u);return rep;}else {rep.setCode(1);rep.setMsg("登陆成功");request.getSession().setAttribute("user", u);return rep;}}else {//4.0 账号密码错误rep.setCode(-1);rep.setMsg("账号或者密码错误，请重新输人");return rep;}}

邮箱激活

激活看似很难理解，确实最简单的，用一个字段int类型来做是否激活的标志位，若1表未激活，若2表激活，在登录的时候验证即可

/*** 邮箱激活*/@RequestMapping("/xiaochengxu/jihuo")public String jihuo(String baseString) {//修改当前的状态即可userServiceImpl.updateByBaseString(baseString);return "user/jihuo";}
