我遇到了primefaces文件上传器的问题，当上传完成时fileUploadListener未调用的处理程序方法我在方法开始中放置了一个断点并且执行正常进行，因为它不存在，没有发生异常：

这是我的文件上传器：

                   <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);  
     }  
}

您应该将以下过滤器添加到web.xml：

<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>

这个问题也很有帮助；）

亲爱的朋友，请消除您的 web.xml 中的一个过滤器映射，它是重复的。
