由一个portlet配置错误引起对liferay的(iferay-portlet.xml,portlet.xml,liferay-display,web.xml)研究

错误

The requested resource (xxx/xxx/invoke) is not available

原因是在web.xml文件少对应的映射配置

JSP对应的配置

<servlet>

<servlet-name>Welcome</servlet-name>

<servlet-class>com.liferay.portal.kernel.servlet.PortletServlet</servlet-class>

<init-param>

<param-name>portlet-class</param-name>

<param-value>com.liferay.util.bridges.jsp.JSPPortlet</param-value>

</init-param>

<load-on-startup>0</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>Welcome</servlet-name>

<url-pattern>/Welcome/*</url-pattern>

</servlet-mapping>

strust2对应的配置

<servlet>

<servlet-name>Welcome
</servlet-name>

<servlet-class>com.liferay.portal.kernel.servlet.PortletServlet</servlet-class>

<init-param>

<param-name>portlet-class</param-name>

<param-value>org.apache.struts2.portlet.dispatcher.Jsr168Dispatcher</param-value>

</init-param>

<load-on-startup>0</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>Welcome</servlet-name>

<url-pattern>/Welcome/*</url-pattern>

</servlet-mapping>

另外配置文件 liferay-portlet.xml,portlet.xml,liferay-display,web.xml之间的关系

portlet.xml

<portlet id='welcomeId'> <!--可以随便起一个ID-->

<description xml:lang='EN'>mesWelcome</description>

<portlet-name>Welcome</portlet-name> <!-- 这个Name 必须与liferay-display.xml当中的portlet 的id一致。另外liferay-portlet.xml的portlet-name最好也与此处的portlet-name一致，如果不一致在添加应用的弹出菜单显示紫色 .在web.xml的servlet-name也需要跟此处的名字相一致-->

<display-name xml:lang='EN'>mesWelcome</display-name>

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

<init-param>

<name>viewNamespace</name>

<value>/myproject/view</value>

</init-param>

<init-param>

<name>defaultViewAction</name>

<value>mesWelcome</value><!-- 由于是应用了struts2 ,对应的是struts.xml里面的某一变量 -->

</init-param>

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

<supports>

<mime-type>text/html</mime-type>

<portlet-mode>view</portlet-mode>

</supports>

<supported-locale>en</supported-locale>

<resource-bundle></resource-bundle>

<portlet-info>

<title>In Portlet.xml Title</title>

<short-title>showTitleOnAddApplication</short-title> <!-- 此处的内容会在添加应用的的菜单显示及添加的porlet的标题显示-->

<keywords>struts2,portlet</keywords>

</portlet-info>

</portlet>

jsp的portlet.xml内容

<portlet>

<portlet-name>Welcome</portlet-name>

<display-name>Welcome</display-name>

<portlet-class>com.liferay.util.bridges.jsp.JSPPortlet</portlet-class>

<init-param>

<name>view-jsp</name>

<value>/view.jsp</value>

</init-param>

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

<supports>

<mime-type>text/html</mime-type>

</supports>

<portlet-info>

<title>WelcomeJsp</title>

<short-title>Welcome</short-title>

<keywords>Welcome</keywords>

</portlet-info>

</portlet>

liferay-display.xml

(strust2与Jsp一致)
