Primefaces FileUpload与PrettyFaces和JSF 2.2.3

Question

我在使用的页面上遇到了漂亮的问题<p:fileupload>.

当我在页面上禁用PrettyFaces过滤器时,一切正常.当我把它放回去时,我可以看到webbrowser上的HTTP流量,但我的fileupload处理程序永远不会被触发.

这是代码的一些相关部分.

任何帮助,将不胜感激!

我的.xhtml

<h:form id="formImportarSNs" enctype="multipart/form-data">  
<p:fieldset legend="Admin Panel">    
   <p:fileUpload value="#{adminPanelBean.file}" mode="simple"/>                            
   <p:commandButton ajax="false" actionListener="#{adminPanelBean.upload}"            value="confirm" />  

</p:fieldset>  
</h:form>

import org.primefaces.model.UploadedFile;  

@ViewScoped  
@ManagedBean  
public class AdminPanelBean{  

    private UploadedFile file;  

    public void upload() {    
        if(arquivo != null) {    
            FacesMessage msg = new FacesMessage("Succesful", file.getFileName() + "     is uploaded.");    
            FacesContext.getCurrentInstance().addMessage(null, msg);    
        }    
    } 

    // getters/setters/etc

编辑:清理了一些代码.

我找到了解决方案.

context.xml在META-INF文件夹中创建并放置此代码:

<?xml version="1.0" encoding="UTF-8"?>
<Context allowCasualMultipartParsing="true">
</Context>

您可以从中删除Fileupload过滤器 web.xml

这就是为什么你需要把它:如何在Tomcat上运行的servlet过滤器中使用HttpServletRequest#getParts()？
