目前,我正试图通过doWithDynamicMethods关闭另一个插件来执行此拦截,如下所示:

def doWithDynamicMethods = { ctx ->

        MetaClass jobMetaClass = klass.clazz.metaClass

        // intercept the methods of the job classes
        jobMetaClass.invokeMethod = { String name, Object args ->

            // do something before invoking the called method
            if (name == "execute") {
                println "this should happen before execute()"
            }

            // now call the method that was originally invoked
            def validMethod = jobMetaClass.getMetaMethod(name, args)

            if (validMethod …
