Grails 这个例外意味着什么？

我在用MAVEN构建Grails应用程序时收到了这条消息，在引导完成后，我在日志中得到了这个异常。有人能告诉我在哪里查找此异常的原因吗？它想说什么

没有任何源代码或您的

Grails版本

，只需查看您的异常stacktrace，就可以发现以下问题：

Error creating bean with name 'instanceControllersApi': Singleton bean creation not allowed while the singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

我对Grails JIRA做了一些研究，下面的JIRA问题与您的stacktrace相同。看看关于这个JIRA问题的stacktrace。根据JIRA问题，它似乎会影响2.0决赛中的

脚手架

，但在2.0.1中已修复

谢谢Philip，我使用的是Grails2.1.0，这发生在maven完成引导并开始测试时。我确实使用静态和动态脚手架，但不确定在那个阶段会发生什么以及为什么会发生这种情况。我非常乐意与大家分享我的代码，但我也不确定是我的项目的哪个部分导致了这个错误。自从添加了一个插入一些测试数据的引导类之后，我也看到了这个错误。我很想知道我能做些什么。@stephan你使用的是什么版本的Grails？不确定它是否相关，但我不确定是什么修复了它。但有两个问题，你们有没有脚手架页面？如果有，他们有没有为他们写的测试？有空测试吗？事实上，我已经为我的大多数域类构建了页面，它们都有存根单元测试。我计划生成它们并在以后充实测试。。。如果这能让错误消失就好了，但我还是想知道真正的原因是什么。
