有沒有辦法爲我的spring portlet提供一個默認狀態,如果發生不可用的表示,那麼這個狀態會被解析?Spring Portlet MVC - 如何捕捉映射異常

我收到此異常

10:24:53,187 ERROR [517: org.jboss.portal.portlet.impl.jsr168.PortletContainerImpl] The portlet threw an exception 
javax.portlet.UnavailableException: No matching handler method found for portlet request: mode 'view', phase 'ACTION_PHASE', parameters map[[empty]] 
    at org.springframework.web.portlet.mvc.annotation.AnnotationMethodHandlerAdapter$PortletHandlerMethodResolver.resolveHandlerMethod(AnnotationMethodHandlerAdapter.java:488) 
    at org.springframework.web.portlet.mvc.annotation.AnnotationMethodHandlerAdapter.invokeHandlerMethod(AnnotationMethodHandlerAdapter.java:354)

    at org.springframework.web.portlet.FrameworkPortlet.processRequest(FrameworkPortlet.java:519) 
    at org.springframework.web.portlet.FrameworkPortlet.processAction(FrameworkPortlet.java:460) 

我想抓住這個異常,並簡單地返回默認的「VIEW」狀態什麼的。

* -portlet.xml

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:context="http://www.springframework.org/schema/context"

     <context:annotation-config/> 
     <!-- Controllers --> 
     <bean id="portletController" class="de.nv.spring.portlets.PortletController"/> 

     <!-- Handler Mappings --> 
     <bean class="org.springframework.web.portlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> 
</beans>

你有一個默認渲染/動作 - 方法?對我來說,下面的默認渲染方法的工作原理:

@RenderMapping(params="!render") 
public String defaultRender(RenderRequest req, RenderResponse res, Model model) throws PortalException, SystemException { 
    // do something 
} 

註釋值呈現表示,這是運行,如果不存在渲染參數。直觀地說,你可以在你的動作參數上使用相同的方法。
