Java如何实现在线高中考试系统(java,开发技术)

项目分为前台和后台，前台主要为学生角色、后台主要为管理员角色。

管理员添加试题和发布试卷，学生负责在线考试、在线查看成绩和错题记录列表等。

管理员功能有：年级管理、课程管理、试题管理、试卷管理、学生管理等。

运行环境：jdk1.8、mysql5.x、eclipse、tomcat8.5\7.0、maven3.5\3.6。

统一管理学生 教师 管理员信息：

/***统一管理学生教师管理员信息*/@RestControllerpublicclassUserController{@Resource(name="userService")privateIUserServiceuserService;/***查询用户信息*先判断用户类型在查询用户信息*/@RequestMapping(value="/user/qryUserInfo",method=RequestMethod.POST,produces={"application/json;charset=UTF-8"})publicResult<User>qryUserInfo(){returnuserService.qryUserInfo();}/***更新用户信息*/@RequestMapping(value="/user/update",method=RequestMethod.POST,produces={"application/json;charset=UTF-8"})publicResult<User>update(HttpRequestrequest){Useruser=newUser();user.setUserId(request.getString("user_id"));user.setName(request.getString("name"));user.setSex(request.getInteger("sex"));user.setType(User.UserType.get(request.getInteger("type")));returnuserService.update(user,ImageUtil.stringToBytes(request.getString("user_image")));}/***更新用户密码*/@RequestMapping(value="/user/updatePwd",method=RequestMethod.POST,produces={"application/json;charset=UTF-8"})publicResult<User>updatePwd(HttpRequestrequest){returnuserService.updatePwd(request.getString("old_pwd"),request.getString("pwd"));}}
