PrintSetup print = exportExcel.getSheet().getPrintSetup(); //拿到sheet对象首先
print.setFitWidth((short)1);
print.setPaperSize(HSSFPrintSetup.A4_PAPERSIZE); //纸张类型
print.setScale((short)68);//自定义缩放①，此处100为无缩放HSSFPrintSetup
exportExcel.getSheet().setAutobreaks(false);
print.setLeftToRight(true);//列从左向右显示②
Footer footer = exportExcel.getSheet().getFooter();
footer.setRight( "Page " + HSSFFooter.page() + " of " + HSSFFooter.numPages());//
POI导出文件缩放至A4纸大小
