Question

我有一个非常简单的Controller方法，它使用Apache POI库下载excel文件，该库在Service类中生成，如下所示：

XSSFWorkbook workbook = new XSSFWorkbook();

// Excel sheet populated and added to workbook

FileOutputStream out = new FileOutputStream(new File("file.xlsx"));
workbook.write(out);

out.close();

以下Controller方法触发下载。

@ResponseBody
@RequestMapping(value = "/fileDownload")
public String downloadMatchingExcel(HttpServletRequest request, HttpServletResponse response) throws IOException{

    response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
    response.setHeader("Content-Disposition", "attachment; filename = file.xlsx");
    response.setHeader("Content-Length", String.valueOf(file.length()));

    FileInputStream is = new FileInputStream(new File("file.xlsx"));

    IOUtils.copy(is, response.getOutputStream());

    response.flushBuffer();
    response.getOutputStream().close();

}

生成并下载文件没有任何问题。但是我在构建日志中收到以下错误。

这是什么意思？这是值得担心的吗？
