Question

有没有办法为我的spring portlet提供一个默认状态，如果发生不可用的expcetion就会解析它？

我接受了这个例外

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)

我想捕获此异常并返回默认的“VIEW”状态或其他内容。

* - portlet.xml中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
        <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>

Answer 1

你有默认的渲染/动作 - 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render-parameter则会运行此操作。直觉上，您可以在action-parameter上使用相同的方法。

已在Spring 3.0.5中修复（请参阅https://jira.springframework.org/browse/SPR-7542?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel）
