List studentReadings = new ArrayList();

    List<UUser> user = userService.queryUserNameByClassId(classId);
    for (int i = 0;i < user.size(); i++){
        studentReadings.get(i).setUserStudentId(user.get(i).getUserStudentId());
        studentReadings.get(i).setUserName(user.get(i).getUserName());
        Integer count = readingLogService.queryReadingCount(user.get(i).getUserId());
        studentReadings.get(i).setReadingCount(count);
        float score = homeworkService.selectInitialScore(user.get(i).getUserId());
        studentReadings.get(i).setCountScore(score);
        studentReadings.get(i).setReadingScore(score);
        List<String> resourceIdList = homeworkService.selectResourceId(user.get(0).getUserId());
        studentReadings.get(i).setReadingCount(resourceIdList.size());
        int readingwordCount = 0;
        for(int j = 0; j < resourceIdList.size(); j ++){
            TArticleInfo articleInfo = articleInfoService.selectWordcount(resourceIdList.get(i));
            readingwordCount =+ articleInfo.getWordcount();
        }
