    导出excle结果一直报这个错误,是在找不到原因

    private void exportExcleFile(SXSSFWorkbook workbook, HttpServletResponse response, String excleName) throws Exception {
        log.info("===== 正在导出Excle =====");
        try (OutputStream outputStream = response.getOutputStream()) {
            response.setContentType("application/octet-stream;charset=UTF-8");
            response.setHeader("Content-disposition", "attachment;filename=" + URLEncoder.encode(excleName, "UTF-8"));
            response.addHeader("Pargam", "no-cache");
            response.addHeader("Cache-Control", "no-cache");
            workbook.write(outputStream);
            response.flushBuffer();
            workbook.dispose();
            log.info("===== Excle导出完成 =====");
        }

      这个错误通常是由于使用完毕的文件流被关闭，导致程序无法再访问文件中的内容。

      例如，你可能使用FileInputStream或FileOutputStream打开一个文件，然后在程序结束时调用close()方法来关闭它。如果你在这个过程中没有使用finally块，那么当文件被关闭时，程序可能会抛出IOException。

      解决这个问题的一个常见方法是使用finally块。在finally块中，无论是否发生异常，你都可以执行任何必要的清理操作。在上面的例子中，你可以添加一个finally块来关闭文件流：

      ```java try { // 打开文件 FileInputStream fis = new FileInputStream("file.txt");

      // 打印文件内容
System.out.println(fis.read());

// 关闭文件流
fis.close();

      } catch (IOException e) { // 处理异常 e.printStackTrace(); } ```

      这样，即使在发生异常的情况下，你也可以确保文件流被正确地关闭，从而防止程序崩溃。
