java - Liferay + Struts2没有为 namespace /testPortlet1和操作名称startTestPortlet1映射的操作，为什么？

我绝对不是Liferay Portlet开发的新手，但遇到以下问题。

当我尝试在Portlet中添加我的第一个Portlet（由我开发）时，我听错了此错误消息：


  testPortlet1暂时不可用。


在我的IDE的stacktrace中，我看到以下错误消息：

2014-12-19 11:37:55,874 [[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'] ERROR commons.CommonsLogger.error(38) - Could not find action

因此，这是与我的Portlet相关的structs.xml部分：

<package name="TestPortlet1Package" extends="struts-portlet-default" namespace="/">
    <action name="startTestPortlet1" class="TestPortlet1Action" method="startTestPortlet1">
        <result name="success">/testPortlet1/testPortlet1.jsp</result>
    </action>
</package>

这是我的JSP视图（在\ Web \ src \ main \ webapp \ testPortlet1 \ testPortlet1.jsp中定义）：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sj" uri="/struts-jquery-tags" %>
<style>
    .portlet-topper#portlet_SliderNewsPortlet_WAR_KMPortlets, .portlet-title#portlet_SliderNewsPortlet_WAR_KMPortlets {
        display: none
    }

    .portlet#portlet_SliderNewsPortlet_WAR_KMPortlets, .portlet-content#portlet_SliderNewsPortlet_WAR_KMPortlets {
        border: 0;
        margin: 0;
        padding: 0;
        background: 0;

    }
</style>
<hr style="height:1px;border:none;color:#1d8843;background-color:#1d8843;width: 98%" size="4px">
<table width="100%">
    <tr>
        <td>
            <table class="homePortletTitle">
                <tr>
                    <td style="padding-bottom: 0px;"><img src="/km-theme/images/km-icons/section_icon_focus.png"></td>
                    <th style="">TestPortlet1</th>
                    <td style="">Hello World Portlet</td>
                </tr>
            </table>
        </td>
    </tr>

    <tr>
        <td>
          <p>Hello World !!!</p>
        </td>
    </tr>
</table>

这是我在portlet.xml文件中定义的portlet配置：

<portlet>

    <portlet-name>testPortlet1</portlet-name>
    <display-name>testPortlet1</display-name>
    <portlet-class>org.apache.struts2.portlet.dispatcher.Jsr168Dispatcher</portlet-class>

    <init-param>
        <name>viewNamespace</name>
        <value>/testPortlet1</value>
    </init-param>

    <init-param>
        <name>defaultViewAction</name>
        <value>startTestPortlet1</value>
    </init-param>

    <expiration-cache>0</expiration-cache>

    <supports>
        <mime-type>text/html</mime-type>
        <portlet-mode>VIEW</portlet-mode>
    </supports>

    <portlet-info>
        <title>testPortlet1</title>
    </portlet-info>

</portlet>

我想念什么？我该如何解决这个问题？我快疯了。

最佳答案

在struts.xml中定义的包名称空间和porlet.xml中的viewNamespace之间不匹配。解决方案：修复struts.xml

<package name="TestPortlet1Package"
         extends="struts-portlet-default"
         namespace="/testPortlet1">
