file-upload - Rich :fileUpload component in (RC 4. 3.4) 在 Apache Tomcat7 和 JSF 2.2 上工作吗？ : "Request prolog cannot be read"

Question

我正在尝试使用richfaces fileupload 组件上传文件。我的 bean 在 View 范围内。

我的代码从展示中提取。

            <rich:fileUpload  id="upload" immediateUpload="true" fileUploadListener="#{analyse.listener}"  acceptedTypes="png" ontyperejected="alert('Seulement les fichiers avec l'extension bam et pdf sont acceptés.');" maxFilesQuantity="3">
                  <a4j:ajax event="uploadcomplete" execute="@none" />        
            </rich:fileUpload>

bean 函数调用:

    public void listener(FileUploadEvent event) throws Exception {


    System.out.println("Listenner");

    UploadedFile item = event.getUploadedFile();

    System.out.println(item.getName());
    System.out.println(item.getSize());
    System.out.println(item.getContentType()) ;

}     

当我尝试添加要上传的文件时，我遇到了一个美丽的错误:-(。欢迎提供帮助。

摘要:使用 <h:inputFile /> ，至少我拿不到<rich:fileUpload>在 JSF-2.2 中工作

长版:
花了一天时间玩弄<rich:fileUpload>我得出的结论是，遵守 Servlet-3.0 规范的 servlet 容器在这里处于摇摆不定的境地。

似乎正在发生的事情是 Tomcat(或任何实现 Servlet-3.0 及更高版本的 servlet 容器 - 我尝试使用 Wildfly 的 undertow)通过 HttpServletRequest#getParts() 使多部分 POST 提交可用。方法。它还可以很好地解析表单数据并通过 ServletRequest#getParameter 使其可用，其中明确指出:

If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via getInputStream() or getReader() can interfere with the execution of this method.

这究竟是什么 MultipartRequest25如果你称之为 getParameter参数名称不存在的方法:

 String parameter = super.getParameter(name);
 if (parameter != null) {
     return parameter;
 }
 parseIfNecessary();

parseIfNecessary()部分尝试读取序言，但由于容器已经解析了请求正文，因此流为空，从中读取会立即产生 EOF翻译成 IOException我们看到了。

从类命名我得到的想法是，这是为 Servlet-2.5 容器编写的，这可能有效，并且信息不容易获得。

在这一点上，我决定利用我对 JSF-2.2 的使用并切换到 h:inputFile当您使用最新的(在撰写本文时)Mojarra-2.2.5(还没有尝试过 Myfaces)时，效果非常好。

下面是一个例子:

<h:form id="fileUploadForm" enctype="multipart/form-data">
    <h:inputFile value="#{docMgr.file}" required="true">
        <f:ajax listener="#{docMgr.saveFile}" render="@form" />
    </h:inputFile>
    <h:messages />
</h:form>

请注意，Mojarra-2.2.5 之前的版本存在 ajax 提交问题，如上例所示(模仿 RichFaces 的 immediateUpload 。
