管理员和教师登陆此账号就进入后台，学生登陆此账号就进入前端做题。

老师发布了考试,学生才可以在主页面看到相应的考试信息。 有考试安排表以后,才能给该次考试添加题目,对应数据表是exammanage。 该表保存该次考试,课程名称,考试时间,所属专业,学院等等信息。

题库表设计和普通数据表设计有所区别。分别是选择题题库表,填空题题库表,判断题题库表, 每个表保存相应类型的题库,通过一张中间表,将题库和试题关联起来。 这样就组成了一张完整的试卷。

管理员的功能：

考试管理、题库管理、成绩查询、学生管理、教师管理

首先需要增加考试，才能在这个考试下，添加题目。题目可以在题库中自由组题。

学生功能：

查看可以做的试卷、已经做的试卷练习、自己每次考试的分数、给管理员留言等。

统一管理学生 教师 管理员信息控制层：

/*** 统一管理学生 教师 管理员信息*/
@RestController
public class UserController {@Resource(name = "userService")private IUserService userService;/*** 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"})public Result<User> qryUserInfo() {return userService.qryUserInfo();}/*** 更新用户信息*/@RequestMapping(value = "/user/update", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})public Result<User> update(HttpRequest request) {User user = new User();user.setUserId(request.getString("user_id"));user.setName(request.getString("name"));user.setSex(request.getInteger("sex"));user.setType(User.UserType.get(request.getInteger("type")));return userService.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"})public Result<User> updatePwd(HttpRequest request) {return userService.updatePwd(request.getString("old_pwd"), request.getString("pwd"));}
}

用户登陆控制层：

@RestController
public class LoginController {@Resource(name = "loginService")private ILoginService loginService;/*** 用户登录调用 在登陆成功生成两个token 同时返回各自首页* * 学生 student/student* * 老师 teacher/teacher* * 管理员 admin/admin*/@RequestMapping(value = "/login/login", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})public Result<Token> login(HttpRequest request) {return loginService.login(request.getString("login_name"), request.getString("pwd"));}/*** 登录检查*/@RequestMapping(value = "/login/check", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})public Result<Token> check() {return new Result<>();}/*** token 续约*/@RequestMapping(value = "/login/refresh", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})public Result<Token> refresh(HttpRequest request) {String refreshToken = request.getString("refresh_token");String urlId = request.getString("url_id");Token token = TokenCache.getInstance().get(urlId);if(token == null){ExceptionHelper.error(ErrorCode.ERROR_CODE_0003);}try {Claims claims = TokenUtils.parseToken(refreshToken);if (StringUtils.isNotEmpty((String.valueOf(claims.getOrDefault("student_id", ""))))) {claims.put("student_id", SessionContext.get("student_id"));}if (StringUtils.isNotEmpty((String.valueOf(claims.getOrDefault("teacher_id", ""))))) {claims.put("teacher_id", SessionContext.get("teacher_id"));}if (StringUtils.isNotEmpty((String.valueOf(claims.getOrDefault("login_name", ""))))) {claims.put("login_name", SessionContext.get("login_name"));}claims.put("name", claims.get("name"));token.setToken(TokenUtils.createToken(claims, TokenUtils.expireTime));token.setRefreshToken(TokenUtils.createToken(claims, TokenUtils.long_expireTime));TokenCache.getInstance().add(token);} catch (Exception e) {ExceptionHelper.error(ErrorCode.ERROR_CODE_0003);}return new Result<>(token);}/*** 退出系统*/@RequestMapping(value = "/login/exit", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})public Result<Token> exit(HttpRequest request) {String urlId = request.getString("url_id");if (StringUtils.isNotEmpty(urlId)) {TokenCache.getInstance().remove(urlId);}return new Result<>();}
}

管理员控制器：

/*** 管理员控制器*/
@RestController
public class AdminController {@Resource(name = "adminService")private IAdminService adminService;/*** 管理员 查询管理员列表*/@RequestMapping(value = "/admin/qryPage", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})@RoleAnnotation(types = {RoleEnum.admin})public ListResult<Admin> qryPage(HttpRequest request) {Map<String, Object> param = new HashMap<>();int pageNo = request.containsKey("page_no") ? request.getInteger("page_no") : 1;int pageSize = request.containsKey("page_size") ? request.getInteger("page_size") : 20;if (request.containsKey("login_name")) {param.put("login_name", request.getString("login_name"));}if (request.containsKey("name")) {param.put("name", request.getString("name"));}return adminService.qryPage(param, pageNo, pageSize);}/*** 管理员 添加管理员*/@RequestMapping(value = "/admin/add", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})@RoleAnnotation(types = {RoleEnum.admin})public Result<Admin> insert(HttpRequest request) {Admin admin = new Admin();admin.setLoginName(request.getString("login_name"));admin.setName(request.getString("admin_name"));admin.setPwd(request.getString("login_name"));admin.setSex(request.getInteger("sex"));admin.setUpdateTime(new Date());return adminService.insert(admin, ImageUtil.stringToBytes(request.getString("admin_image")));}/*** 管理员 更新管理员*/@RequestMapping(value = "/admin/update", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})@RoleAnnotation(types = {RoleEnum.admin})public Result<Admin> update(HttpRequest request) {Admin admin = new Admin();admin.setLoginName(request.getString("login_name"));admin.setName(request.getString("admin_name"));admin.setPwd(request.getString("login_name"));admin.setSex(request.getInteger("sex"));admin.setUpdateTime(new Date());return adminService.update(admin, ImageUtil.stringToBytes(request.getString("admin_image")));}/*** 管理员 删除管理员*/@RequestMapping(value = "/admin/del", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})@RoleAnnotation(types = {RoleEnum.admin})public Result<Admin> del(HttpRequest request) {List<String> adminIdList = new ArrayList<>();JSONArray array = request.getJSONArray("admin_id_list");for (int i = 0; i < array.size(); i++) {adminIdList.add(array.getString(i));}return adminService.del(adminIdList);}
