springportletmvc-如何捕获映射异常

portlet spring java

有没有办法为我的springportlets提供一个默认状态,如果出现不可用的表达式,该状态将被解析?

我收到这个例外

10:24:53,187 ERROR [517: org.jboss.portal.portlet.impl.jsr168.PortletContainerImpl] The portlet threw an exception

你有默认的渲染/动作方法吗?对于我来说,以下默认渲染方法有效:

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