文件上传不适用于PrimeFaces 4.0,PrettyFaces 3.3.3和GlassFish 4

我尝试使用p:fileUpload但是没有调用fileUploadListener方法,也没有生成任何异常。没有PrettyFaces,文件上传工作正常。

经过一番研究,我发现重写常见问题解答(http://ocpsoft.org/rewrite/docs/faq)回答了“为什么文件上传不能正常工作?”可能是解决方案,但仅在To​​mcat上进行测试。我在GlassFish上试过但没有成功。

然后我在OcpSoft论坛上发现了一个解决我问题的帖子:http://ocpsoft.org/support/topic/pretty-primefaces-fileupload/page/2/#post-25781。只需将文件上传代码放在其他页面源代码中,并使用html iframe标记进行引用。

好的,问题解决了,但我对iframe解决方案不满意,而fileUploadListener方法应该在没有解决方法的情况下调用。那么,任何人都知道如何配置文件上传与PrettyFaces一起使用?

    private UploadedFile uploadedFile;
    private String uploadedFileName;

    public void handleFileUpload(FileUploadEvent evt) {
        this.uploadedFile = evt.getFile();
        this.uploadedFileName = evt.getFile().getFileName();
    }


    public String getUploadedFileName() {
        return uploadedFileName;
    }


    public void setUploadedFileName(String uploadedFileName) {
        this.uploadedFileName = uploadedFileName;
    }
}

和web.xml:

这可能是一个过滤器链问题。尝试在注册过滤器中添加以下内容:

<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>

答案 1 :(得分:0)

对于我来说,使用Primefaces 5.0&amp; Prettyfaces在Tomcat 7.0.41上重写2.0.12-final。

但是我从web.xml

中删除了这部分内容
<filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>
        org.primefaces.webapp.filter.FileUploadFilter
    </filter-class>
    <init-param>
        <param-name>thresholdSize</param-name>
        <param-value>51200000</param-value>
    </init-param>
    <init-param>
        <param-name>uploadDirectory</param-name>
        <param-value>/uploadedFilesDirectoryForGlassfish</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

并添加到context.xml这个:

<Context allowCasualMultipartParsing="true">

p:fileUpload 也开始在重写的网址上正常工作。

This page可能有用。

另见:http://www.ocpsoft.org/rewrite/docs/faq&amp; this SO answer


但等等,

刚刚观察到它只适用于小文件上传,对于大文件上传,fileUpload侦听器仍然没有被触发。有解决方案的人吗?
