Primefaces FileUpload with PrettyFaces 和 JSF 2.2.3 [英] Primefaces FileUpload with PrettyFaces and JSF 2.2.3

问题描述

我在使用 的页面上使用 PrettyFaces 时遇到了一些问题.

I'm having some problems with PrettyFaces on the pages I use <p:fileupload>.

当我禁用页面上的 PrettyFaces 过滤器时，一切正常.当我把它放回去时，我可以在网络浏览器上看到 HTTP 流量，但我的文件上传处理程序从未被触发.

When I disable the PrettyFaces filter on the page, everything works just fine. When I put it back, I can see the HTTP traffic on the webbrowser, but my fileupload handler is never fired.

这是代码的一些相关部分.

This is some relevant part of the code.

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);    
        }

清理了一些代码.

推荐答案

我找到了解决方案.

在 META-INF 文件夹中创建 context.xml 并放置以下代码:

Create the context.xml in the META-INF folder and put this code:

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

您可以从 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()?

And that's why you need to put it: How to use HttpServletRequest#getParts() in a servlet filter running on Tomcat?

如果您的问题是文件的大小，请查看:<p:文件上传>限制为 2 Mb

If your problem is the size of the file, take a look at: <p:fileUpload> limiting to 2 Mb
