PageHelper使用案例

    @Override
    public CommonResult queryReportByCallCountInfos(ReportByCallVo reportByCallVo) {
        PageHelper.startPage(reportByCallVo.getPageNum(), reportByCallVo.getPageSize());
        List<ReportByCallVo> list = sysUsageStatisticsMapper.queryReportByCallCountInfos(reportByCallVo);
        PageInfo<ReportByCallVo> pageInfo = new PageInfo<>(list);
        if(list!=null){
            return CommonResult.success(pageInfo);
        }else {
            return CommonResult.failed("查询异常");
        }

    }
