绕过 grails 视图解析器？

我正在尝试在 grails 应用程序中构建一个 portlet，并且创建了一个扩展 AbstractController 的简单控制器，它

从 返回 new ModelAndView('myportlet')处理请求内部。我还有一个针对 /WEB-INF/jsp 的标准 Jstl 视图解析器 设置，但无论我尝试什么，当我尝试在 liferay 中查看 portlet 时，我都会得到以下信息stacktrace：

13:19:39,723 ERROR [DispatcherPortlet:559] Could not complete request
java.lang.ClassCastException: org.springframework.web.portlet.context.PortletRequestAttributes cannot be cast to org.codehaus.groovy.grails.web.servlet.mvc.GrailsWebRequest
    at org.codehaus.groovy.grails.web.util.WebUtils.retrieveGrailsWebRequest(WebUtils.java:497)
    at org.codehaus.groovy.grails.web.servlet.view.GrailsViewResolver.loadView(GrailsViewResolver.java:87)
    at org.codehaus.groovy.grails.scaffolding.view.ScaffoldingViewResolver.loadView(ScaffoldingViewResolver.java:61)
    at org.springframework.web.servlet.view.AbstractCachingViewResolver.createView(AbstractCachingViewResolver.java:158)
    at org.springframework.web.servlet.view.UrlBasedViewResolver.createView(UrlBasedViewResolver.java:384)
    at org.springframework.web.servlet.view.AbstractCachingViewResolver.resolveViewName(AbstractCachingViewResolver.java:77)
    at org.springframework.web.portlet.DispatcherPortlet.resolveViewName(DispatcherPortlet.java:1110)

看来如果我能够绕过 GrailsViewResolver，我应该能够像在正常的 Spring 应用程序中一样启动并运行我的 portlet。

我使用的是 liferay 6，所以 grails liferay 插件不是一个选项。我可以做些什么来确保 GrailsViewResolver 不会尝试解析 /WEB-INF/jsp 中的视图？

原文

I'm trying to build a portlet within a grails application, and I've created a simple controller extending AbstractController which returns

new ModelAndView('myportlet') from handleRequestInternal. I also have a standard Jstl view resolver setup for /WEB-INF/jsp but no matter what I try, when I try to view the portlet within liferay I get the following stacktrace:

13:19:39,723 ERROR [DispatcherPortlet:559] Could not complete request
java.lang.ClassCastException: org.springframework.web.portlet.context.PortletRequestAttributes cannot be cast to org.codehaus.groovy.grails.web.servlet.mvc.GrailsWebRequest

    at org.springframework.web.portlet.DispatcherPortlet.resolveViewName(DispatcherPortlet.java:1110)

It seems that if I could get around the GrailsViewResolver, I should be able to get my portlet up and running as I would in a normal spring application.

I'm using liferay 6, so the grails liferay plugin isn't an option. Is there anything I can do to make sure GrailsViewResolver doesn't try to resolve my view in /WEB-INF/jsp?
