当我尝试向客户端浏览器发送数据时出现此异常。我使用 apache POI lib 生成一个 Excel 文件，如下例所示：

workbook = generateData();
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition", "attachment; filename=" + this.filename);
out = response.getOutputStream();
workbook.write(out);

这适用于少量数据，但每次我尝试使用大量数据时它都不起作用。应用程序需要超过 30 秒来生成数据，这是否太长了，我可以阻止吗？
