有人知道怎么解决这个问题吗？Thx.

这可能不是您想要听到的，但标准HTTP协议无法很好地用于上传大型文件。通常，在对等套接字应用程序中，客户机和服务器都可以在大型传输过程中保持连接健康并保持一切活动。然而，对于HTTP和web，客户端通常只有cookie是有状态的。客户端无法知道它的cookie是否仍然有效（更正：除非它们被明确设置为在特定日期过期），直到将cookie提供给服务器并获得带有结果的响应

因此，服务器需要在会话的生命周期上强加一个时间线，在该时间过后，它将抛出会话的有状态信息。典型的internet连接的上载速度往往比下载速度稍慢，而会话在等待上载大文件时失效的情况并不罕见，这一事实使这一点更加复杂

您有三种选择：

增加服务器上的会话超时过期时间。也许这会给你足够的时间

您使用富客户机界面（Flash、Applet、Silverlight等），并通过将文件上传到您的网页来使用此富客户机。这里的好处是，您可以将大文件分解为可管理的二进制块，并使用会话cookie一次一个地将它们发送到服务器。每个成功的区块请求都会在整个传输过程中保持会话的活动状态。您的服务器在收到最后一个区块后可以重新组装您的大文件并将其持久化

除了利用HTML5和JS的强大功能外，基本上做与#2相同的事情。下面是一个开源Javascript库，它利用HTML5技术将大型文件分解成块，并帮助在服务器上重新组装它们。这种方法的一些缺点是，由于它使用的是HTML5，它只能在现代浏览器上工作，因此对IE7等旧浏览器的支持是值得怀疑的

关于第3点的另一个注意事项是，将此Javascript代码包含在自定义或复合JSF组件中并不超出可能的范围，该组件将允许您在客户端和服务器之间实现更精简的接口

另见以下问题：
