Java如何实现在线高中考试系统

这篇文章主要介绍了Java如何实现在线高中考试系统，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

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