好吧，我改变了参数，我从 web.xml 文件中删除了过滤器，我改变了 bean...我知道我必须有一个“multipart/form-data”表单，一个 web.xml 文件中的过滤器和一个fileUploader 在 bean 中接收事件。但是什么都没有触发。我单击选择然后上传（如果参数不是 auto="true"）并且没有任何反应。我有 commons-io-2.4、commons-fileupload-1.3、primefaces-3.5，我使用 GlassFish Server 4。谢谢！

我没有尝试过 GlassFish，但发现在 WebLogic 上使用 PrimeFaces 4 我们必须将此参数添加到 web.xml：

<context-param>
    <param-name>primefaces.UPLOADER</param-name>
    <param-value>commons</param-value>
</context-param>

我们正在使用这个 Maven 依赖项：

<dependency>
   <groupId>commons-fileupload</groupId>
   <artifactId>commons-fileupload</artifactId>
   <version>1.3.1</version>
</dependency>

我们还必须确保它PrimeFaces FileUpload Filter是 web.xml 中的第一个过滤器条目。但看起来你的已经是了。

此外，文件上传应该有自己的形式。
