JSF 1.2 富文件上傳拋出IOException

Question

我正在嘗試在 Glassfish 4.1 上使用 java8、JSF 1.2、RichFaces 3.3.3.Final、.net.java.dev.ajax4jsf 1.0.6 在一個非常舊的系統中實現 rich:fileUpload。 系統很大所以請不要讓我更新它，這將需要 10 年:)

我已經砍了很多天了，一直在撞牆。 任何幫助或指導將不勝感激。

當我打開 web 應用程序時，我能夠 select 一個文件並單擊上傳，然后它在那里掛了一兩秒鍾然后失敗。 它永遠不會到達我的支持 bean。

這是我到目前為止所擁有的：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");
    }

當我嘗試上傳文件時，我得到：

Answer 1

以下代碼在多年前的 RichFaces 項目中為我工作（它來自 RichFaces 4，但我猜 RichaFaces 3 中使用的非常相似）：

<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>

但在我的例子中，上傳參數是在 web.xml 中以不同的方式設置的：

<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>

即使在大多數情況下沒有必要，您也可以在應用程序的lib文件夾中添加commons-fileupload-1.3.1.jar 。 請檢查 jar 版本，對於較舊的 RichFaces，它可能會更低。

您可以在此處驗證X-Frame-Options header 的值。 如果 header 的值不正確，有時文件上傳不起作用。
