使用PrettyFaces和JSF 2.2.3的Primefaces FileUpload [英] Primefaces FileUpload with PrettyFaces and JSF 2.2.3
问题描述
我在使用< p：fileupload> 的网页上遇到PrettyFaces的问题。
当我禁用页面上的PrettyFaces过滤器时，一切正常。当我把它放回去，我可以看到浏览器上的HTTP流量，但我的文件上传处理程序永远不会被触发。
这是代码的相关部分。
任何帮助将不胜感激！

编辑：清理了一些代码。
我找到了解决方案。
$ b 创建
context.xml 放在META-INF文件夹中，然后输入以下代码： <？xml version =1.0encoding =UTF- 8\" >？;
< Context allowCasualMultipartParsing =true>
< / Context>
您可以从 web.xml中删除Fileupload Filter

如果你的问题是文件的大小，请看一下：<号码：文件上传>限制为2 Mb
I'm having some problems with PrettyFaces on the pages I use <p:fileupload>.
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.
This is some relevant part of the code.
Any help would be appreciated!
My .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>

private UploadedFile file;

<view-id value="/faces/xhtml/admin_panel.xhtml" />
</url-mapping>
</pretty-config>
Edit: Cleaned up some code.
I've found the solution.
Create the context.xml in the META-INF folder and put this code:
<?xml version="1.0" encoding="UTF-8"?>
<Context allowCasualMultipartParsing="true">
</Context>
You can remove the Fileupload Filter from web.xml

And that's why you need to put it: How to use HttpServletRequest#getParts() in a servlet filter running on Tomcat?
If your problem is the size of the file, take a look at: <p:fileUpload> limiting to 2 Mb
