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 */ @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")); } }
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); } }

登录控制层:
@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<>(); } }
