Primefaces文件上传器不会调用处理器方法

Question

我有一个primefaces文件上传器的问题，当上传完成fileUploadListener中的处理器方法没有调用时，我在方法启动中放置了一个断点并且执行正常进行因为它是不存在的，没有例外发生：

这是我的文件上传：

    <h:form enctype="multipart/form-data"> 
        <p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload}" 
         mode="advanced" update="messages" sizeLimit="100000" 
         allowTypes="/(\.|\/)(gif|jpe?g|png)$/" 
         <h:message style="color:red;margin:8px;"/> 
         <p:growl id="messages" showDetail="true" /> 
        </h:form> 

，这是处理程序：

@ManagedBean(name="fileUploadController") 
@SessionScoped 
public class FileUploadController { 

public void handleFileUpload(FileUploadEvent event) { 
    FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded."); 
    FacesContext.getCurrentInstance().addMessage(null, msg); 
    } 
} 

web.xml中

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

你应该以下过滤器添加到web.xml中：

<filter> 
    <filter-name>PrimeFaces FileUpload Filter</filter-name> 
    <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class> 
</filter> 
<filter-mapping> 
    <filter-name>PrimeFaces FileUpload Filter</filter-name> 
    <servlet-name>Faces Servlet</servlet-name> 
</filter-mapping> 

EDIT1：

而且this question可以是有益的; ）

EDIT2：

亲爱的朋友，请消除在web.xml的过滤器映射之一，它的复制。
