是啊，下面是我自己写的 可是我想用上面的呢 配置了<portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class> 会自动在WEB-INF下面寻找<portlet-name>-portlet.xml 我在这个xml里面配置了 

	<bean id="helloWorldController" class="com.demo.HelloWorldController" />
	
	<bean id="portletModeHandlerMapping"
		class="org.springframework.web.portlet.handler.PortletModeHandlerMapping">
		<property name="portletModeMap">
			<map>
				<entry key="view">
					<ref bean="helloWorldController" />
				</entry>
			</map>
		</property>
	</bean>

	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="cache" value="true" />
		<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>
就不行了。 而配置 <portlet-class>com.demo.HelloWorldPortalDemo</portlet-class> 

package com.demo;

import java.io.IOException;

import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

public class HelloWorldPortalDemo extends GenericPortlet
{
    @Override
    protected void doView(RenderRequest request, RenderResponse response)
            throws PortletException, IOException
    {
        response.setContentType("text/html");
        
        getPortletContext().getRequestDispatcher("/WEB-INF/jsp/helloWorld.jsp")
                .include(request, response);
    }
}
就可以

<portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class> 上面配置的是spring的 <portlet-class>com.demo.HelloWorldPortalDemo</portlet-class> 下面是你扩展的。

portlet.xml里面配置 <portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class> 就出错 直接配置成 <portlet-class>com.demo.HelloWorldPortalDemo</portlet-class> 就好了。 真奇怪。
