jsf - ICEfaces/Seam文件上传组件未上传文件

Question

更新资料

我目前正在ICEfaces论坛上解决我的问题-不幸的是，所提供的选项现在都没有导致解决方案，但是它们的确为我提供了对整个JSF主题的更多见解（为此，信贷给BalusC，因为经常:-)）。

如果问题最终得到解决，以帮助其他可能遇到的问题，我将尝试使该线程保持最新状态并发布答案。

到目前为止，我的发现是：


需要禁用Seam Multipart Filter，因为它会阻止fileEntry-component正常工作
我的应用程序中仍然存在一些讨厌的库问题，导致（静默的）ClassLoading问题：存在2个icefaces-ace.jar文件，一个在EAR / lib中，一个在EAR / WAR / WEB-INF / lib中。从WEB-INF中删除一个导致组件什么都不做，从EAR / lib中删除一个导致我的应用程序不再部署。


当将所有前端jar（icefaces.jar，icefaces-ace.jar，icefaces-compat.jar）从EAR / lib移动到WEB-INF / lib时，我的EAR的jar部分收到各种ClassNotFoundExceptions：ValueChangeEvent，RowSelectorEvent等找不到。（也就是说，所有这些事件都从视图进入后端）。例：

整个故事

我正在使用Seam 2.3和ICEfaces 3.1.0开发Web应用程序。这意味着正在使用JSF2。

我的应用程序作为EAR部署在JBoss AS 7.1.0上，包含用于应用程序逻辑的JAR和用于所有与视图相关的东西的WAR。

我最近从Seam 2.1.2迁移到Seam 2.3，从ICEfaces 1.8.2迁移到3.1.0。这一步很可怕，但是现在一切正常，撇开了一些小问题。

唯一的大问题是，当我使用组件上载文件时，无论使用Seam组件还是ICEfaces组件-在Seam中，上载的文件始终为null，而在ICEfaces中，永远不会调用我的fileEntryListener-Method。

使用ICEfaces：

在2.X之前的ICEfaces版本中，存在 ice:inputFile组件，该组件已由2.X删除并由 ace:fileEntry代替。

InputFile运作良好，但FileEntry却无法运作。我的问题与中所述完全相同
JSF : Issues with File Upload using Icefaces component-从不调用fileEntryListener。我在那里尝试了建议（在周围的表单上使用enctype =“ multipart / form-data”，在表单上使用 h:commandButton提交），但是没有用。提供的唯一解决方案是切换到Richfaces，这对我来说不是一个选择。

带缝：

很高兴，Seam拥有自己的内置fileUpload-component， s:fileUpload。

它也不起作用，但至少向我展示了一个可以进一步查找的地方。在调试该组件的doDecode-Methods时，我发现我的请求不是MultipartRequest。疯了！用于上传文件的所有表单都将Enctype声明为multipart / form-data。我认为，当我尝试使用ICEfaces组件时，也会发生同样的情况-没有多部分请求，因此不会调用任何侦听器。

所以：我该如何工作？没有请求作为MultipartRequest出现的意义是什么？我会错过web / components.xml中的某些内容吗？

web.xml：

示例JSF源（接缝）

    <s:decorate>
    <s:fileUpload data="#{uploadBean.fileData}"
        contentType="#{uploadBean.contentType}"
            fileName="#{uploadBean.fileName}" />
    <h:commandButton value="Upload File" type="submit" />
   </s:decorate>
</h:form>

JSF源示例（ICEfaces）

<h:form enctype="multipart/form-data">
    <ace:fileEntry id="file-entry" relativePath="/files/"
            fileEntryListener="#{uploadBean.uploadFile}"
        useSessionSubdir="true" />

    <h:commandButton id="submit" type="submit" value="Send File" />
</h:form>

JSF映射到一个Seam组件，其中fileData的字节[]和fileName和contentType的字符串为String。 fileEntryListener映射到一个以 FileEntryEvent作为输入的void方法。



更新资料

为了让您了解最新信息，到目前为止我的发现：

考虑到BalusC的回答，我更深入地研究了过滤器内容。我已经尝试添加/删除Seam Multipart Filter，但是现在我发现，当我将其添加到components.xml中并通过显式禁用它时

<web:multipart-filter disabled="true"/>

ICEfaces至少发生了一些事情：FileEntryPhaseListener引发了异常，以前从未发生过：

At least this is something to look at. If I use the fileEntryListener like

fileEntryListener="#{uploadBean.fileUploadListener}"

如果使用以下方法，则会引发上述异常：

fileEntryListener="#{uploadBean.fileUploadListener()}"

它抱怨该方法需要参数，如果我像这样使用它：

fileEntryListener="#{uploadBean.fileUploadListener(null)}"

没有引发异常，但是由于事件为null，所以没有文件到达我的UploadBean。闻起来像图书馆的一些问题，但至少还有其他需要看的地方。

上载bean

这里发生的事情不多，只是：

@Stateful
@Name("uploadBean")
@Scope(ScopeType.SESSION)
@JndiName(value = "java:app/myApp.jar/UploadBean")
public class UploadBean implements IUploadBean
{
public void fileUploadListener(FileEntryEvent event)
{
    System.out.println("listener called!");
}   
 }

侦听器也在bean的接口中声明。

Answer 1

首先介绍一些技术背景信息：在即将发布的JSF 2.2之前，JSF本身并不支持multipart/form-data请求。因此，提供文件上传组件的组件库必须自己提供一个自定义Filter。这应该正确解析multipart/form-data请求并将所有必需的常规数据存储在HTTP请求参数映射中，并将上载的文件存储为请求属性。这样，JSF可以继续以常规方式将request.getParameter()用作常规数据，并且组件库本身可以获取上载的文件作为请求属性。

对于Seam的<s:fileUpload>，您需要org.jboss.seam.web.MultipartFilter来执行multipart/form-data解析作业。我从未使用过Seam（也不使用ICEfaces），但是Google向我展示了您基本上在webapp的web.xml中需要此功能

<filter>
    <filter-name>Seam Multipart Filter</filter-name>
    <filter-class>org.jboss.seam.web.MultipartFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>Seam Multipart Filter</filter-name>
    <url-pattern>*.seam</url-pattern>
</filter-mapping>

或在Seam components.xml中：

<web:multipart-filter url-pattern="*.seam" />

ICEfaces组件必须配置类似的过滤器。缺少ICEfaces 3.x文档（或者我的Google / icefaces.com的搜索技能很差），因此我无法对此进行详细介绍。

请记住，重要的是HTTP请求只能被解析一次（客户端仅发送一次，而不是多次发送），因此您不能在同一请求上同时使用两个 multipart/form-data解析器。在第一个请求之后插入的请求将获得一个空的请求正文，该请求正文无法解析为任何明智的内容。因此，如果您使用的是使用后一个过滤器的组件，那么模型中什么也不会得到。确保您并非偶然或通过实验配置两者。
