我的项目介绍

springmvc 实战在线考试零碎，学生自主注册账号，抉择本人所在班级，进行在线模拟考试。我的项目次要分为用户治理，资源管理，考试治理，试卷治理，作业管理，问题治理等几个大的模块，针对每个模块划分管理员、教室、学生三种角色，给予每个不同角色相应的页面，操作逻辑以及权限。

具体实现

1. 老师角色增加试卷 

// 前端试卷创立
<div class="panel-body">
  <form:form action="${ctx}/exampaper/save" method="post" cssClass="form-horizontal"
    enctype="multipart/form-data" modelAttribute="entity">
    <form:hidden path="id" />
    <div class="form-group">
      <label for="name" class="col-sm-2 control-label"> 试卷名 </label>
      <div class="col-sm-4">
        <form:input cssClass="form-control" path="name"  autocomplete="off"/>
      </div>
    </div>
    <div class="form-group">
      <label for="description" class="col-sm-2 control-label"> 形容 </label>
      <div class="col-sm-4">
        <form:textarea cssClass="form-control" path="description" />
      </div>
    </div>
    <div class="form-group">
      <label for="content" class="col-md-2 control-label"> 题目文件 </label>
      <div class="col-md-5">
        <input name="file" type="file" accept="application/vnd.ms-excel,
          application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"/>
      </div>
    </div>
    <div class="col-md-8 text-center">
      <button class="btn btn-primary" type="submit"> 提交 </button>
      &emsp;&emsp;&emsp;&emsp;
      <a class="btn btn-warning" href="${ctx}/exampaper/list"> 返回 </a>
    </div>
  </form:form>
</div>

// 后端解决
public String save(@ModelAttribute("entity") ExamPaper examPaper, @RequestParam("file") MultipartFile file) { CallBackMessage msg;
    try {InputStream inputStream = file.getInputStream();
        List<Question> questions = ExcelToQuestionUtils.readQuestions(inputStream);
        inputStream.close();
        examPaper.setQuestions(questions);
        examPaper.setClassId(Integer.valueOf(CurrentUtils.getCurrentUser().getClassId()));
        return baseSave(examPaper);
    } catch (IOException e) {e.printStackTrace();
        msg = CallBackMessage.createDangerMsg("服务器异样，请重试！");
    } catch (EncryptedDocumentException e) {e.printStackTrace();
        msg = CallBackMessage.createDangerMsg("题目文档已被加密，无奈辨认！");
    } catch (InvalidFormatException e) {e.printStackTrace();
        msg = CallBackMessage.createDangerMsg("题目文档格局有误！");
    } catch (IllegalArgumentException e) {e.printStackTrace();
        msg = CallBackMessage.createDangerMsg(e.getMessage());
    }
    msg.addToCurrentSession();
    return redirect(LIST_PATH);
}
  1. 创立考试，与试卷绑定 
// 前端 JSP 代码
<div class="col-xs-10">
  <div class="panel panel-info">
    <div class="panel-heading">
      <h3 class="panel-title">

          <label for="name" class="col-sm-2 control-label"> 考试名称 </label>
          <div class="col-sm-4">
            <form:input cssClass="form-control" path="name" autocomplete="off" />

          </div>
        </div>
          <div class="form-group">

                      <span class="input-group-addon">  <span class="glyphicon glyphicon-calendar"></span> </span>
                  </div>
              </div>

        </div>
      </form:form>
    </div>
  </div>
</div>
// 后端入库解决
public String save(@RequestParam("exampaperId") Long exampaperId,@ModelAttribute(ENTITY_ATTRIBUTE_NAME) Exam entity) {ExamPaper examPaper = exampaperService.findByID(exampaperId);
    examPaper.setClassId(Integer.valueOf(CurrentUtils.getCurrentUser().getClassId()));
    entity.setExampaper(examPaper);
    entity.setClassId(Integer.valueOf(CurrentUtils.getCurrentUser().getClassId()));
    return baseSave(entity);
}

操作流程

  1. admin 用户创立老师角色并绑定所属班级
  2. 老师角色登录治理后盾，上传题库并创立试卷
  3. 将创立的试卷进行考试绑定，明确告知学生考试是具体那一试卷
  4. 学生自行注册并选中所属班级，注册登录后能看到本人所属班级是有考试
  5. 进行考试作答并提交，期待批改
  6. 查看错题及问题
  7. 额定还有课件下载及作业和布告查看性能
