try {
String realpath = ResourceUtil.getConfigByName("realpath");
String downpath = realpath + tsAttachment.getRealpath();// 拼接全路径
List<CcReportFormEntity> list = new ArrayList<CcReportFormEntity>();
FileInputStream fis = new FileInputStream(downpath);
Workbook wb = new HSSFWorkbook(fis);
Sheet sht = wb.getSheetAt(0);
for (Row r : sht) {
if (r.getRowNum() < 1) {
continue;
}
CcReportFormEntity reportFormEntity = new CcReportFormEntity();
reportFormEntity.setModelNumber(r.getCell(0).getStringCellValue());   取得每一排的第一列
