Primefaces Mobile p：fileupload上传方法，不称为

我正在开发一个移动设备的Web应用程序，用户可以在多个场合上传文件（图像）。

由于我使用的是Primefaces移动渲染工具包，因此我必须使用Primefaces的简单p:fileupload而不使用ajax。

问题： 当我想上传图像时，我可以选择文件（组件正确呈现），然后点击“上传”按钮。点击“上传”后，页面会刷新，但永远不会调用myBean.saveImage()。 myBean.fileUploadController.setFile也未被调用。我没有在Netbeans控制台中收到任何错误消息，也没有在Chromes JS控制台中收到任何错误消息。

到目前为止，我尝试使用自5.0版以来的primefaces支持的本机HTTP Servlet上传和旧的commons.fileupload方式 - 结果相同。

我按this great guide对p:fileupload进行了问题排查，但在完成指南中建议的所有内容后，我仍然得到相同的结果。

我创建了一个fileuploadtest.xhtml页面来测试上传功能，如下所示：

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui"
    xmlns:pm="http://primefaces.org/mobile">

    <f:view renderKitId="PRIMEFACES_MOBILE" />

    <h:head>

    </h:head>

    <h:body>

        <pm:page>
            <pm:header title="Title"></pm:header>

            <pm:content>
                <h:form enctype="multipart/form-data">
                    <p:fileUpload value="#{myBean.fileUploadController.file}" mode="simple"/>
                    <p:commandButton value="Upload" ajax="false" action="#{myBean.saveImage}"/>
                </h:form>
            </pm:content>

            <pm:footer title="Footer"></pm:footer>
        </pm:page>
    </h:body>

</html>

这是我的bean和我的FileUploadController类：

MyBean.java：

    @Component
    @Scope("session")
    @Named
    public class MyBean implements Serializable {

        @Autowired(required = true)
        private FileUploadController fileUploadController;

        //Bunch of unrelated methods

        public void saveImage() {
             this.fileUploadController.upload();
             //some more code after upload() is complete
        }
        //getters&setters
    }

FileUploadController.java：

@Component
@Scope("session")
public class FileUploadController {

    private UploadedFile file;

    public boolean upload() {
        if (file != null) {
            //upload here
            return true;
        } else {
            return false;
        }
    }

    public UploadedFile getFile() {
        return file;
    }

    public void setFile(UploadedFile file) {
        this.file = file;
    }
}

这是我的web.xml：

我将此web.xml配置为使用commons.fileupload而不使用HTTP Servlet本机上载功能。

请注意，我必须用空格（'/ *'）分隔'/ *'，这样我的其余代码就不会被格式化为注释。 （如果有更聪明的方法，请不要犹豫告诉我）

我的网络应用程序依赖于以下技术/库：

JSF 2.2.9

HTTP Servlet 3.0.1

Spring MVC

Spring Webflow

使用<f:view renderKitId="PRIMEFACES_MOBILE" />

的Primefaces 6.0

Omnifaces 1.5

Bootsfaces 0.8.1

Netbeans as IDE

出于测试和调试目的，我通过Netbeans将应用程序部署到Jetty 8.1.5。

但是我尝试将应用程序部署到Tomcat服务器并获得相同的结果。

请原谅长篇文章，我只想包含一些看起来很有用的东西。如果您还有其他需要请告诉我。

非常感谢你。

编辑：

我的问题似乎与p:fileupload没有任何关系，而是当我禁用ajax时，我的p:commandButton根本没有调用任何动作事件。为了测试这一点，我将ajax="false"属性添加到另一个页面上的一个comandButtons中。一旦我添加它，我的commandButton就停止了工作，它只刷新了网站，但从未处理过action属性中指定的事件。有没有人知道为什么我的命令按钮停止使用ajax="false"？

EDIT2

我发布了new question，因为我发现问题与略有不同的问题有关
