基于Java实现考试管理系统

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。

效果图展示

主要代码

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"));
            }

            }
            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<>();
    }
}

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"));
