我使用了primefaces的fileDownload组件。如果用户第一次成功下载任何文件，下次如果用户没有选择任何文件下载并尝试下载，则抛出以下错误..

我在尝试找到与我的问题完全相同的解决方案时找到了您的问题，但最后我找到了解决方案，如果您想在此处查看我的答案：

Primefaces downloadFile java.io.IOException: Stream Closed after second time

我希望这会对你有所帮助。

javax.faces.FacesException：java.io.IOException：Stream在p：fileDownload中填充了primefaces
