好吧，我更改了参数，我从web.xml文件中删除了过滤器，我更改了bean ...我知道我必须有一个“multipart / form-data”表单，web.xml中的过滤器file和一个fileUploader来接收bean中的事件。但是什么也没有触发。我点击选择然后上传（如果参数不是auto =“true”）并且没有任何反应。我确实有commons-io-2.4，commons-fileupload-1.3，primefaces-3.5和我使用GlassFish Server 4。谢谢！

Answer 2

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>

我们正在使用这种Maven依赖：

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

我们还必须确保PrimeFaces FileUpload Filter是web.xml中的第一个过滤条目。但它看起来已经是你的了。

此外，文件上传应该有自己的形式。
