我已经发布了一个关于几天前的问题。p:fileupload在深入研究这个问题后，我意识到我的主要问题似乎来自不同的起源，因此我提出了一个新问题。
我正在为移动设备开发一个网络应用程序（JSF2.2），用户可以在其中多次上传文件。我想使用 Primefaces 的p:fileupload组件来完成这项似乎不起作用的工作。我发现问题似乎enctype="multipart/form-data"与<h:form>. 每当我的表单中有此属性时，commandButton 都不会调用其action=""属性中指定的 bean 方法（使用时也不会actionListener=""）。当我删除该enctype="multipart/form-data"属性时，除了文件上传之外，一切都正常工作。
出于测试和调试目的，我创建了一个uploadTest.xhtml当前看起来如下的页面：
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:p="http://primefaces.org/ui"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html">
<f:view renderKitId="PRIMEFACES_MOBILE" />
<h:head>
</h:head>
<h:body>
<h:form id="dasistmeineform" enctype="multipart/form-data">
<p:fileUpload value="#{uploadBean.uploadedFile}" mode="simple"/>
<p:commandButton action="#{uploadBean.upload}" ajax="false" value="upload" />
</h:form>
</h:body>
</html>
为了从可能的错误原因列表中排除 Primefaces，我还创建了另一个测试页面，其中我只使用<h:inputFile>并且<h:commandButton>没有 primefaces 组件。这给了我同样的结果。
这是我的 UploadBean.java：
import javax.faces.bean.RequestScoped;
import javax.faces.bean.ManagedBean;
import org.primefaces.model.UploadedFile;
@ManagedBean
@RequestSoped
public class UploadBean {
private UploadedFile uploadedFile;
public UploadedFile getUploadedFile() {
return uploadedFile;
}
public void setUploadedFile(UploadedFile uploadedFile) {
this.uploadedFile = uploadedFile;
}
public void upload() {
if (this.getUploadedFile() != null) {
System.out.println("Hurray!");
}
}
}
我个人的猜测是，这个问题与应用程序的设置方式或 JSF 在应用程序中的实现方式有关。为了解决这个问题，我遵循了@BalusC 的JSF 设置指南。此外，我遵循了他的一些其他故障排除指南，包括如何排除 p:fileupload 故障以及按下 h:commandButton 时未调用 bean 方法的可能原因列表。不幸的是，到目前为止没有任何帮助。
我在 Netbeans 控制台和 Chrome 的开发人员控制台中都没有收到错误。按下上传按钮后，我可以使用开发人员工具看到 HTTP 请求。响应的代码为 200，所以一切都应该在 HTTP 端正常工作，对吧？
Web 应用程序使用以下组件：
JSF 2.2.13 (莫哈拉)
春季网络流
春季MVC
Primefaces 5.3
全方位 1.3
靴面 0.9.1
该应用程序直接通过 Netbeans 在 Jetty 8.1.5 服务器上部署和测试。
为了检查我是否下载了所有必要的依赖项，我将包含我的 pom.xml 的相关方（我使用 maven）：
<dependencies>

我包括commons-io并commons-fileupload测试是否p:fileupload可以使用旧的（在 Servlet 3.0 之前）方式，但它没有。
这是我的 web.xml ：（请注意，我也在没有成功的情况下测试了context-paramandfilter条目p:fileupload）：

请注意，我必须用空格 (´/ *´) 分隔“/*”，以便我的其余代码不会被格式化为注释。（如果有更聪明的方法可以做到这一点，请不要犹豫告诉我）
Spring 的 MVC Dispatcher Servlet 会以某种方式干扰 Servlet 3.0 的上传功能吗？
我是否使用了其他违反 Servlet 3.0 文件上传标准行为的组件？
我的项目是否设置正确？
非常感谢。即使是一点提示也将不胜感激。
