Uploading large files with HttpClient
提问by user592704
I want to upload large video files (>=1Gb) with HttpClientto a servlet but I couldn't find any real examples.
Could you give me some useful code examples?
我想将大型视频文件 (>=1Gb) 上传HttpClient到 servlet，但找不到任何真实示例。你能给我一些有用的代码示例吗？
I'd like to see both the HttpClient and FileUpload demo codes (as a one project). And it is quite interesting can I use FileUpload lib to download large files?
我想同时查看 HttpClient 和 FileUpload 演示代码（作为一个项目）。很有趣，我可以使用 FileUpload lib 下载大文件吗？
It is interesting to have upload bound like this applet -> servlet
像这样的applet -> servlet 绑定上传是很有趣的

I'm not sure that you mean by "real". It's real enough, even if it doesn't precisely match your situation.
我不确定你的意思是“真实”。它足够真实，即使它与您的情况不完全匹配。
1GB? You're likely to have file size limitation issues. Try it locally and see. If it fails, at least you'll have some real code and more exact conditions to post here.
1GB？您可能会遇到文件大小限制问题。在本地试试看。如果它失败了，至少你会有一些真实的代码和更精确的条件可以在这里发布。

I am able to upload large files >200mb , Please look into below jsp to spring controller code .
我可以上传大于 200mb 的大文件，请查看下面的 jsp 到 spring 控制器代码。
Jsp code :
