java - 上传 .pdf、.doc 或 .docx 时出现 HTTP 错误。使用 primefaces 上传工具上传文件

Question

我从昨天开始使用 Primefaces 上传工具，但今天我开始使用不同的文件扩展名来测试它。让我惊讶的是，我唯一可以成功上传的文件是 .txt 我不明白为什么会这样。我在网上看到了代码片段，我认为我的代码几乎是相同的。我错过了什么吗？

这里有更多信息:

这是错误:

WARNING: StandardWrapperValve[Faces Servlet]: PWC1406: Servlet.service() for servlet Faces Servlet threw exception java.io.IOException: Processing of multipart/form-data request failed. \uploaded\upload_3be1503c_12f00f7e117__7ffb_00000007.tmp (The system cannot find the path specified) at org.primefaces.webapp.MultipartRequest.parseRequest(MultipartRequest.java:67) at org.primefaces.webapp.MultipartRequest.(MultipartRequest.java:49)

这是 JSF 的代码

<h:form enctype="multipart/form-data">

  <!-- New Upload tool -->
        <p:fileUpload fileUploadListener="#{uploadController.handleFileUpload}"   
        allowTypes="*.doc;*.docx;*.pdf;*.odt;" description="Text"/>

</h:form>

这是托管 bean 的代码的一部分

            public void handleFileUpload(FileUploadEvent event) {

    uploadedFile = event.getFile();
    String fileName = FilenameUtils.getName(uploadedFile.getFileName());
    String contentType = uploadedFile.getContentType();
    byte[] bytes = uploadedFile.getContents();

    Garbage garbage = new Garbage();
    garbage.setFilename(fileName);
    garbage.setFile(bytes);
    garbage.setDescription("info about the file");
    garbage.setFileType("File extension");
    fileUploaderEJB.uploadGarbage(garbage);

    FacesContext.getCurrentInstance().addMessage(
            null,
            new FacesMessage(String.format(
                    "File '%s' of type '%s' successfully uploaded!",
                    fileName, contentType)));
}

以防万一，web.xml 中与 primefaces 相关的内容

<servlet>
<servlet-name>Resource Servlet</servlet-name>
<servlet-class>org.primefaces.resource.ResourceServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Resource Servlet</servlet-name>
<url-pattern>/primefaces_resource/*</url-pattern>
</servlet-mapping> 
 <filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>org.primefaces.webapp.filter.FileUploadFilter
    </filter-class>
    <init-param>
        <param-name>uploadDirectory</param-name>
        <param-value>/uploaded</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

\uploaded\upload_3be1503c_12f00f7e117__7ffb_00000007.tmp (The system cannot find the path specified)

与安装网络服务器的位置相同的根磁盘上的文件夹 /uploaded 丢失。创建它。
