Primefaces 文件上传不会上传大于 1 MB 的文件
Primefaces File Upload won't upload files greater than 1 MB
**Primefaces 不允许我上传大于 1 MB 的文件，如图所示。该代码适用于我的本地 tomcat 服务器，但不适用于 Amazon prod tomcat 服务器。任何建议请我什至使用 maxPostSize 但它不起作用。我猜问题出在 server.xml 上，因为代码工作正常。 **

这个 post 问题已经解决。问题不在于我的 tomcat。我有一个 Nginx 服务器 运行 阻止所有超过 1 MB 的上传。要解决此问题，只需在 /etc/nginx/nginx.conf 文件的下方块中设置此参数即可。这将允许上传高达 100 Mb
