Liferay和struts2

对不起，可能英文不好。Liferay和struts2

我尝试在struts2 liferay portlet中下载docx文件。

在我的portlet.xml我指定的portlet类：在struts.xml中

<portlet-name>test-portlet</portlet-name> 
<display-name>Test</display-name> 
    <portlet-class>org.apache.struts2.portlet.dispatcher.Jsr286Dispatcher</portlet-class> 
    <init-param> 
     <name>viewNamespace</name> 
     <value>/view</value> 
    </init-param>

操作：

<action name="GenerateReport" class="org.test.GenerateReportAction" 
     method="generateReport"> 
     <result name="success" type="stream"> 
      <param name="inputName">resultInputStream</param> 
      <param name="contentType">application/msword</param> 
      <param name="contentDisposition">attachment;filename="Test_SumaryReport.docx"</param> 
      <param name="bufferSize">1024</param> 
      <param name="contentLength"></param> 
     </result> 
    </action>

在JSP中：

<a href='<s:url action='GenerateReport' > </s:url>'>download</a>

当我尝试下载文件我有例外：

10:26:59,805 ERROR [Jsr168Dispatcher:38] Could not execute action java.lang.IllegalArgumentException: application/msword is not a supported mime type

为什么Liferay在Portlet类Jsr286Dispatcher时使用Jsr168Dispatcher？

如果你知道如何解决这个问题，它会很高兴知道它！

非常感谢！

见我回答这个问题：http://stackoverflow.com/q/17721094/1700321。 –

@AleksandrM亲爱的Aleksandr，谢谢你的回答！如果在中使用portletUrlType =“resource”，当我尝试下载文件时，在浏览器中打开新的空白选项卡并抛出exceprion：12：35：37,289错误[Jsr168Dispatcher：38]无法找到操作没有操作映射到操作名称GenerateReport。 - [未知位置]可能是什么问题？ – user3318963

发布完整的struts.xml文件并显示呈现的url。 –

引用我的回答从https://stackoverflow.com/a/17743269/13447：

有用于Liferay的一个sample-struts portlet其中包含未嵌入完整的门户页面下载的自定义类型 - 例如内容类型可能与通常的门户网站的HTML不同。在this example它是图像/ jpeg。根据你的问题应用这个。

您必须明白，对您的struts动作的典型“动作”请求将是结果HTML页面的部分，例如，它必须是适当的HTML mimetype。如果您执行资源请求（例如Aleksandr M在ERROR: application/pdf is not a supported mime type的回答中建议），则可以提供任何内容类型。

Jsr168Dispatcher是supertype of Jsr286Dispatcher。所以对于Jsr286Dispatcher没有重写的每个方法，stacktrace列出了实际实现一个方法的类。
