public void setTotal(long total) {
        this.total = total;
        if (total == -1) {
            pages = 1;
            return;
        }
        // 如果pageSize<=0, 则直接设置pages=0; pageSize默认为0
        if (pageSize > 0) {
            pages = (int) (total / pageSize + ((total % pageSize == 0) ? 0 : 1));
        } else {
            pages = 0;
        }
        //分页合理化，针对不合理的页码自动处理
        if ((reasonable != null && reasonable) && pageNum > pages) {
            pageNum = pages;
            calculateStartAndEndRow();
        }
    }

// 返回值page对象
Page<StudyRecordVo> pageResult = new Page<>();
// 不设置pageSize,setPages方法调用无效, setTotal方法覆盖了pageResult的pages属性
// 解决方案: 1. 设置pageSize属性在调用setTotal方法之前; 2. setTotal方法调用之后在设置pages属性
pageResult.setPageSize(pageDto.getPageSize());
pageResult.setPages(totalPages);
pageResult.setTotal(totalElements);
pageResult.addAll(studyRecordVoList);
