if(resultData.getSuccess()){
    BackDataInfo data = resultData.getData();
    int totalRecords = data.getTotal();
    int currentPageSize = data.getPageSize();
    totalPageNumber = (int)Math.ceil(totalRecords * 1.0 /currentPageSize);
    log.info("totalRecords:" + totalRecords);
    log.info("currentPageSize:" + currentPageSize);
    log.info("totalPageNumber:" + totalPageNumber);
}

 1. 将总条数乘以“1.0”转成小数类型

2. 调用Math.ceil向上取数转成int类型
