项目简述本系统功能包括：
支持单选题、多选题、判断题支持学生(student)、教师(teacher)、管理员(admin)三种角色学生：参加考试和查看我的考试教师：学生的所有权限+创建/编辑题目+创建/编辑考试管理员：教师的所有权限+管理用户。

项目运行环境配置：
Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX（Webstorm也行）+ Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）。

项目技术 Springboot + Maven + Jpa+ Vue 等等组成，B/S模式 + Maven管理等等。

主要代码 【基于Java实现考试管理系统】登录控制层：

@RestControllerpublic 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 = "https://www.it610.com/login/login", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})public Result login(HttpRequest request) {return loginService.login(request.getString("login_name"), request.getString("pwd")); } /*** 登录检查*/@RequestMapping(value = "https://www.it610.com/login/check", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})public Result check() {return new Result<>(); } /*** token 续约*/@RequestMapping(value = "https://www.it610.com/login/refresh", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})public Result 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 = "https://www.it610.com/login/exit", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})public Result exit(HttpRequest request) {String urlId = request.getString("url_id"); if (StringUtils.isNotEmpty(urlId)) {TokenCache.getInstance().remove(urlId); }return new Result<>(); }}

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 */@RestControllerpublic 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 = "https://www.it610.com/user/qryUserInfo", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})public Result qryUserInfo() {return userService.qryUserInfo(); } /*** 更新用户信息*/@RequestMapping(value = "https://www.it610.com/user/update", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})public Result 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 = "https://www.it610.com/user/updatePwd", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})public Result updatePwd(HttpRequest request) {return userService.updatePwd(request.getString("old_pwd"), request.getString("pwd")); }}

学生管理控制器：

/** * 学生控制器 */@RestControllerpublic class StudentController { @Resource(name = "studentService")private IStudentService studentService; /*** 管理员查询学生列表*/@RequestMapping(value = "https://www.it610.com/student/qryPage", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})@RoleAnnotation(types = {RoleEnum.admin})public ListResult qryPage(HttpRequest request) {Map 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("student_id")) {param.put("student_id", request.getString("student_id")); }if (request.containsKey("name")) {param.put("name", request.getString("name")); }return studentService.qryPage(param, pageNo, pageSize); } @RequestMapping(value = "https://www.it610.com/student/add", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})@RoleAnnotation(types = {RoleEnum.admin})public Result insert(HttpRequest request) {Student student = new Student(); student.setStudentId(request.getString("student_id")); student.setName(request.getString("student_name")); student.setPwd(request.getString("student_id")); student.setSex(request.getInteger("sex")); student.setClassId(request.getString("class_id")); student.setUpdateTime(new Date()); return studentService.insert(student, ImageUtil.stringToBytes(request.getString("student_image"))); } @RequestMapping(value = "https://www.it610.com/student/update", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})@RoleAnnotation(types = {RoleEnum.admin})public Result update(HttpRequest request) {Student student = new Student(); student.setStudentId(request.getString("student_id")); student.setName(request.getString("student_name")); student.setPwd(request.getString("student_id")); student.setSex(request.getInteger("sex")); student.setClassId(request.getString("class_id")); student.setUpdateTime(new Date()); return studentService.update(student, ImageUtil.stringToBytes(request.getString("student_image"))); } @RequestMapping(value = "https://www.it610.com/student/del", method = RequestMethod.POST, produces = {"application/json; charset=UTF-8"})@RoleAnnotation(types = {RoleEnum.admin})public Result del(HttpRequest request) {List studentIdList = new ArrayList<>(); JSONArray array = request.getJSONArray("student_id_list"); for (int i = 0; i < array.size(); i++) {studentIdList.add(array.getString(i)); }return studentService.del(studentIdList); } }
