酒店管理系统
一、项目介绍
1、项目用到的技术栈
开发工具：idea
语言：java、js、html+ajax
数据库：MySQL
服务器：Tomcat
框架：mybatis、jQuery、springboot、vue
2、项目实现功能
管理员和用户登录和退出功能以及用户注册功能（根据不同的账号密码进入不同的页面，注册页面以及登录都有校验）
用户可以预定房间，可以查看预定完房间的基本信息
管理员和用户可以查看个人信息，并且可以修改个人信息（修改时支持信息回显）
管理员和用户可以通过模糊查询和多条件查询
管理员可以对房间进行增删改查（增删房型，增删改查房间）
3.系统展示
3.1 登录
用户进入酒店登陆界面。输入自己的注册所用的账号、密码，点击登录按钮。前端向后台接口地址/login发起ajax请求，后台验证账号是否存在，账号对应密码是否正确。账号、密码验证正确后，登陆成功，反之失败。
界面实现效果如图3-1所示。

登录成功后，前端根据后端返回的角色类型，进入不同的操作页面进行展示，
后端根据不同的账号返回角色对应的数据进行展示
管理员后台操作页面
Controller层
/*** 登录*/@IgnoreAuth@PostMapping(value = "/login")public R login(String username, String password, String captcha, HttpServletRequest request) {UserEntity user = userService.selectOne(new EntityWrapper<UserEntity>().eq("username", username));if(user==null || !user.getPassword().equals(password)) {return R.error("账号或密码不正确");}String token = tokenService.generateToken(user.getId(),username, "users", user.getRole());return R.ok().put("token", token);}
Service层
@Overridepublic String generateToken(Long userid,String username, String tableName, String role) {TokenEntity tokenEntity = this.selectOne(new EntityWrapper<TokenEntity>().eq("userid", userid).eq("role", role));String token = CommonUtil.getRandomString(32);Calendar cal = Calendar.getInstance(); cal.setTime(new Date()); cal.add(Calendar.HOUR_OF_DAY, 1);if(tokenEntity!=null) {tokenEntity.setToken(token);tokenEntity.setExpiratedtime(cal.getTime());this.updateById(tokenEntity);} else {this.insert(new TokenEntity(userid,username, tableName, role, token, cal.getTime()));}return token;}
用户后台操作页面
Controller层
/*** 登录*/@IgnoreAuth@RequestMapping(value = "/login")public R login(String username, String password, String captcha, HttpServletRequest request) {YonghuEntity user = yonghuService.selectOne(new EntityWrapper<YonghuEntity>().eq("yonghuming", username));if(user==null || !user.getMima().equals(password)) {return R.error("账号或密码不正确");}String token = tokenService.generateToken(user.getId(), username,"yonghu", "用户" );return R.ok().put("token", token);}
Service层
@Overridepublic String generateToken(Long userid,String username, String tableName, String role) {TokenEntity tokenEntity = this.selectOne(new EntityWrapper<TokenEntity>().eq("userid", userid).eq("role", role));String token = CommonUtil.getRandomString(32);Calendar cal = Calendar.getInstance(); cal.setTime(new Date()); cal.add(Calendar.HOUR_OF_DAY, 1);if(tokenEntity!=null) {tokenEntity.setToken(token);tokenEntity.setExpiratedtime(cal.getTime());this.updateById(tokenEntity);} else {this.insert(new TokenEntity(userid,username, tableName, role, token, cal.getTime()));}return token;}
员工后台操作页面
Controller层
/*** 登录*/@IgnoreAuth@RequestMapping(value = "/login")public R login(String username, String password, String captcha, HttpServletRequest request) {YuangongEntity user = yuangongService.selectOne(new EntityWrapper<YuangongEntity>().eq("yuangonggonghao", username));if(user==null || !user.getMima().equals(password)) {return R.error("账号或密码不正确");}String token = tokenService.generateToken(user.getId(), username,"yuangong", "员工" );return R.ok().put("token", token);}
Service层
@Overridepublic String generateToken(Long userid,String username, String tableName, String role) {TokenEntity tokenEntity = this.selectOne(new EntityWrapper<TokenEntity>().eq("userid", userid).eq("role", role));String token = CommonUtil.getRandomString(32);Calendar cal = Calendar.getInstance(); cal.setTime(new Date()); cal.add(Calendar.HOUR_OF_DAY, 1);if(tokenEntity!=null) {tokenEntity.setToken(token);tokenEntity.setExpiratedtime(cal.getTime());this.updateById(tokenEntity);} else {this.insert(new TokenEntity(userid,username, tableName, role, token, cal.getTime()));}return token;}
