基于Java實現(xiàn)考試管理系統(tǒng)

更新時間：2021年12月23日 16:12:02 作者：qq_1334611189

這篇文章主要介紹了基于Java實現(xiàn)的考試管理系統(tǒng)，項目運用到的技術有Springboot、Maven、Jpa、Vue等等，感興趣的小伙伴可以跟隨小編一起學習一下

項目簡述

本系統(tǒng)功能包括：

支持單選題、多選題、判斷題支持學生(student)、教師(teacher)、管理員(admin)三種角色學生：參加考試和查看我的考試教師：學生的所有權(quán)限+創(chuàng)建/編輯題目+創(chuàng)建/編輯考試管理員：教師的所有權(quán)限+管理用戶。

項目運行

環(huán)境配置：

Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX（Webstorm也行）+ Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）。

項目技術

Springboot + Maven + Jpa+ Vue 等等組成，B/S模式 + Maven管理等等。

主要代碼

登錄控制層：

@RestController
public class LoginController {
 
    @Resource(name = "loginService")
    private ILoginService loginService;
 
    /**
     * 用戶登錄調(diào)用 在登陸成功生成兩個token 同時返回各自首頁
     * * 學生 student/student
     * * 老師 teacher/teacher
     * * 管理員 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"));
    }
 
    /**
     * 登錄檢查
     */
    @RequestMapping(value = "/login/check", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    public Result<Token> check() {
        return new Result<>();
    }
 
    /**
     * token 續(xù)約
     */
    @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);
    }
 
    /**
     * 退出系統(tǒng)
     */
    @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<>();
    }
}

統(tǒng)一管理學生教師管理員信息：

 
 
/**
 * 統(tǒng)一管理學生 教師 管理員信息
 */
@RestController
public class UserController {
 
    @Resource(name = "userService")
    private IUserService userService;
 
    /**
     * 查詢用戶信息
     * 先判斷用戶類型 在查詢用戶信息
     */
    @RequestMapping(value = "/user/qryUserInfo", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    public Result<User> qryUserInfo() {
        return userService.qryUserInfo();
    }
 
    /**
     * 更新用戶信息
     */
    @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")));
    }
 
    /**
     * 更新用戶密碼
     */
    @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"));
    }
}

學生管理控制器：

/**
 * 學生控制器
 */
@RestController
public class StudentController {
 
    @Resource(name = "studentService")
    private IStudentService studentService;
 
    /**
     * 管理員 查詢學生列表
     */
    @RequestMapping(value = "/student/qryPage", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    @RoleAnnotation(types = {RoleEnum.admin})
    public ListResult<Student> 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;

            param.put("student_id", request.getString("student_id"));

    }
 
    @RequestMapping(value = "/student/add", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    @RoleAnnotation(types = {RoleEnum.admin})
    public Result<Student> insert(HttpRequest request) {

    }
 
    @RequestMapping(value = "/student/update", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})

    @RequestMapping(value = "/student/del", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
    @RoleAnnotation(types = {RoleEnum.admin})
    public Result<Student> del(HttpRequest request) {
