Spring 在Grails中从Quartz作业渲染GSP

我有一份需要提交GSP的quartz工作，当我尝试：

def g = new org.codehaus.groovy.grails.plugins.web.taglib.ApplicationTagLib()
def text = g.render(template: "/templates/myTemplate",
          model: [language: language,
                  product: product])

我收到了以下例外情况：

org.quartz.JobExecutionException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request. [See nested exception: java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread?

使用Grails1.3.2。我能做些什么来让它工作呢？

编辑：Grails目前的一个限制是使用插件。

因为Grails 2.0.4可以使用插件

grails.gsp.PageRenderer.render

在请求上下文之外呈现模板。

谢谢！这对我来说效果很好，我打算添加对请求上下文的模拟，以使模板在我的应用程序中工作，但是有一个插件我已经可以使用了，这很好。请注意，为了避开这个问题，我不得不对其进行一些修改：GrailTemplateEngineService line 45控制器名称应该是pluginNames。这里有一个使用PageRender.render的好例子
