Java毕业设计实战之在线高中考试系统的实现
作者：qq_1334611189
这是一个使用了java+SSM+Jsp+Mysql+Maven开发的在线高中考试系统，是一个毕业设计的实战练习，具有考试系统该有的所有功能，感兴趣的朋友快来看看吧
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"));
}
}
