JSF 1.2丰富的文件上传投掷ioException

Question

我正在尝试使用Java8，JSF 1.2，Richfaces 3.3.3.final，net.java.java.dev.ajax4jsf 1.0.6在非常旧的系统中实现File rich：FileUpload。该系统很大，所以请不要要求我更新它，这将需要10年的时间:)

我已经砍了很多天了，一直撞到墙上。任何帮助或指导将不胜感激。

当我打开Web应用程序时，我可以选择一个文件并单击上传，然后将其悬挂一两秒钟，然后失败。它永远不会到达我的衬里。

这就是我到目前为止的： 在我的xhtml中：

xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:a4j="http://richfaces.org/a4j"
xmlns:c="http://java.sun.com/jstl/core"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:rich="http://richfaces.org/rich

<h:form enctype="multipart/form-data">
   <rich:fileUpload fileUploadListener="#{fileUploadBean.fileUploadListener}"/>
</h:form>

在我的web.xml中：

  <filter>
    <display-name>RichFaces Filter</display-name>
    <filter-name>richfaces</filter-name>
    <filter-class>org.ajax4jsf.Filter</filter-class>
      <init-param>
          <param-name>createTempFiles</param-name>
          <param-value>false</param-value>
      </init-param>
  </filter>
  <filter-mapping>
    <filter-name>richfaces</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
  </filter-mapping>
  <filter>

在我的fileuploadbean.java

@ManagedBean(name = "fileUploadBean")
@SessionScoped
public class FileUploadBean{

    public void fileUploadListener(UploadEvent uploadEvent) throws FileNotFoundException {
        FacesContext facesContext = FacesContext.getCurrentInstance();
        ServletContext servletContext = (ServletContext)facesContext.getExternalContext().getContext();
        String realTargetPath = servletContext.getRealPath("/");
        UploadItem uploadItem = uploadEvent.getUploadItem();
        String filePathname = uploadItem.getFileName();
        String fileName = "";
        System.out.println("STOP");
    }

Answer 1

在几年前的Richfaces项目中为我工作后的代码（这是来自Richfaces 4，但我想在Richafaces 3中使用了非常相似的方法）：

<h:form id="bannerSetupForm" enctype="multipart/form-data">
    <rich:fileUpload id="bannerUploader"
        fileUploadListener="#{retailerAction.bannerListener}"
        acceptedTypes="png, gif, jpg, jpeg"
        noDuplicate="true"
        ontyperejected="alert('#{msg.bannerFormatRestriction}');"
        maxFilesQuantity="1"
        addLabel="#{msg.bannerUploadAddButtonLabel}"
        uploadLabel="#{msg.bannerUploadUploadButtonLabel}">
        <a4j:ajax event="uploadcomplete" execute="@none"
            render="bannerPreviewPopup, bannerAccordionItem" />
    </rich:fileUpload>
</h:form>

但是，就我而言，以不同的方式在Web.xml中设置了上传参数：

<context-param>
    <param-name>org.richfaces.fileUpload.maxRequestSize</param-name>
    <param-value>524288</param-value>
</context-param>
<context-param>
    <param-name>org.richfaces.fileUpload.createTempFiles</param-name>
    <param-value>false</param-value>
</context-param>

即使在大多数情况下，在没有必要的情况下，您可以在您的应用程序的 lib 文件夹中添加 commons-fileupload-1.3.1.jar 。请检查jar版本，至于较旧的Richfaces，可能会较低。

您可以验证 x-frame-options header的值大小限制在富丽堂子里4 fileup“>此处。有时，如果标题值不正确，则文件上传不起作用。
