Grails doWithDynamicMethods访问服务

我难以使用DynamicMethod访问Dow内的特定服务

def doWithDynamicMethods = { ctx ->
        def nodeDriverProxy  = application.getServiceClass('NodeDriverProxyService')
        application.domainClasses.each{ cClass ->
            delegate.log.warn('cClass: ' + cClass.toString())
            cClass.metaClass.cacheInstance = { domainIns->
                delegate.log.warn "domain is being cached id: ? with version ?"
                nodeDriverProxy.registerUpdate(domainIns.id, domainIns.version)
            }

变量nodeDriveProxy为null，或者我在访问“application.serviceClasses”时遇到异常我做错了什么？谢谢

您不需要

GrailsServiceClass

，您需要的是服务实例。您有

ctx

变量，它是Spring

ApplicationContext

，因此

def doWithDynamicMethods = { ctx ->
   def service = ctx.nodeDriverProxyService
   application.domainClasses.each { cClass ->
      delegate.log.warn('cClass: ' + cClass.toString())
      cClass.metaClass.cacheInstance = { domainIns ->
         delegate.log.warn "domain is being cached id: ? with version ?"
         service.registerUpdate(domainIns.id, domainIns.version)
      }
   }
}

谢谢你，伯特。你真的很棒。我从您对其他grails开发人员的其他回答中学到了很多。谢谢你的帮助
