Question

我正在使用JSF和PrimeFaces 5.0开发Web项目。虽然有很多关于这个问题的论坛，但我无法通过FileUpload找到解决方案。问题是，当我在Uplaod上永远不会调用文件处理程序方法时

这是我的代码：

HTML页面

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" 
xmlns:ui="http://java.sun.com/jsf/facelets" 
xmlns:h="http://java.sun.com/jsf/html" 
xmlns:f="http://java.sun.com/jsf/core" 
xmlns:p="http://primefaces.org/ui">
<ui:composition template="/WEB-INF/templates/template.xhtml">

    <ui:define name="content">
        <f:view>
            <p:panel id="panel" header="Registros de Fuente" style="width:100%;">

                <h:form enctype="multipart-data">
                    <p:fileUpload fileUploadListener="#{registrosBean.handleFileUpload}"
                                    required="true" mode="advanced" dragDropSupport="false"
                                    multiple="true" sizeLimit="1000000" fileLimit="5" update="messages"
                                    allowTypes="/(\.|\/)(gif|jpe?g|png|pdf|doc|docx)$/">
                    </p:fileUpload>
                </h:form>

                <h:form enctype="multipart/form-data">
                    <p:fileUpload value="#{registrosBean.file}" mode="simple" />
                    <p:commandButton value="Submit" ajax="false"/>
                </h:form>
            </p:panel>
        </f:view>
    </ui:define>
</ui:composition>
</html>

BEAN：

@Component("registrosBean")
@ViewScoped
@ManagedBean
public class RegistroBean extends GenericBean<Registrofuente> implements Serializable {

    public void handleFileUpload(FileUploadEvent event) {
        System.out.println("SOME CONSOLE MESSAGE");
    }

    public void cogerArchivos( ) {
        System.out.println("SOME CONSOLE MESSAGE");
    }

    public UploadedFile file;

    /**
     * @return the file
     */
    public UploadedFile getFile() {
        return file;
    }

    /**
     * @param file the file to set
     */
    public void setFile(UploadedFile file) {
        System.out.println("SOME CONSOLE MESSAGE");
        this.file = file;
    }
}

的web.xml：

有关我的项目的一些附加信息

JSF 2.1
IDE：Eclipse
Jboss 7.1

说我已经将commons-io和commons-fileupload库添加到WEB-INF \ lib文件夹

这一点很重要

我已经很多天了，并就这个问题咨询了许多论坛，我找不到解决方案，任何建议都会有所帮助。谢谢

首先尝试简化web.xml上的过滤器。试试这个。

<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>

因为你已经在使用PF5，所以你不需要WEB-INF \ lib上的那些公共文库。删除它们。

Primefaces 5 fileUpload处理程序未调用
