Grails 2.3.8 Stacktrace不显示我的任何调用代码

标签： grails

我的控制器中有一个从某个地方调用的方法。据我所知，我的代码中没有任何东西在调用它，所以我添加了一个堆栈跟踪输出行，看看我是否可以告诉它从哪里调用。有了这个，这就是方法的样子：

def remediationSearch() {
        println " "; println ">>>>>> remediationSearch() start at " + System.nanoTime()
        new Exception("why are you calling me?!?!").printStackTrace()
        def resultList
        if (params.rerender) {
            println "<><><> remediationsearch() called with rerender."
            resultList = recordSearchService.individualSearch(session.oldIndRemedParams)
        }
        else {
            params.selectedBatch = selectedBatch
            session.oldIndRemedParams = params
            resultList = recordSearchService.individualSearch(params)
            println "<><><> remediationsearch() called fresh."
        }
        render(template: 'indivSearchResults', model: [resultList: resultList, resultCount: resultList?.size()])
        println "<<<<<< remediationSearch() end at " + System.nanoTime(); println " ";
    }

这是堆栈跟踪的输出，我似乎无法理解（部分是因为我是Grails的新手），因为我似乎没有看到任何编码函数：

    >>>>>> remediationSearch() start at 67861365037047

答案 0 :(得分：1)

如果将此输出与“真实”请求进行比较，您将看到基本相同的事情。这是我期望看到的 - 过滤器链中的各种过滤器被调用，然后是servlet的服务方法（请注意，servlet是GrailsDispatcherServlet，它扩展了Spring的DispatcherServlet），然后它转到doPost这很奇怪，因为这是一个POST请求，但这似乎是一个GET，然后到doDispatch（Grails指出在哪里路由请求），然后到{{1 }}

Grails应用程序SimpleControllerHandlerAdapter.handle中只有一个Spring MVC控制器。它充当Grails控制器和Spring MVC之间的桥梁。 Grails控制器只是Groovy类，所以它们不能注册为Spring MVC控制器，而是这个控制器实例处理所有请求并在SimpleGrailsController的帮助下告诉它控制器和方法（基于反向）从请求的URL到MixedGrailsControllerHelper中的条目的URL映射，它使用反射来调用控制器方法。这就是为什么在你的控制器动作之前有一个URLMappings.groovy。 springloaded Method.invoke就在那里，因为springloaded在开发模式下添加了重新加载支持，但是否则可以忽略它。

您最好的选择是在调试模式下运行应用程序并设置一些断点，以便您可以找出所请求的URL。在此之前 - 设置这些类的Log4j级别进行调试，也许这会有一些有用的东西。
