有没有办法为我的 Spring Portlet 提供默认状态,如果发生不可用的异常,该状态会得到解决?
我收到此异常
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]]

我想捕获此异常并仅返回默认的“VIEW”状态或其他内容。

最佳答案
您有默认的渲染/操作方法吗?对我来说,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
}
注释值!render表示如果不存在渲染参数则运行此函数。直观上,您可以对操作参数使用相同的方法。
