Primefaces文件上傳器不會調用處理器方法

Question

我有一個primefaces文件上傳器的問題，當上傳完成fileUploadListener中的處理器方法沒有調用時，我在方法啓動中放置了一個斷點並且執行正常進行因爲它是不存在的，沒有例外發生：

這是我的文件上傳：

    <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> 

，這是處理程序：

@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"

你應該以下過濾器添加到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：

親愛的朋友，請消除在web.xml的過濾器映射之一，它的複製。
