问使用FlatFileReader读取XLSX

EN

String fileName = "E:\\LLS-6192013-42631.csv";
   File file = new File(fileName);
   FileSystemResource fsr = new FileSystemResource(fileName);


   XSSFWorkbook workbook = new XSSFWorkbook(fileName);
   int sheetIndex = 0;
   XSSFSheet sheet = workbook.getSheetAt(sheetIndex);
   //System.out.println("sheet content : " + sheet); 



   ApplicationContext appContext = new ClassPathXmlApplicationContext(
     "classpath:/launch-context.xml");

   @SuppressWarnings("rawtypes")
   FlatFileItemReader flatFileItemReader = (FlatFileItemReader) appContext
     .getBean("redemptionReader");

   flatFileItemReader.setResource(resource);
