grails - 这个异常是什么意思？

Question

我在使用 MAVEN 构建 Grails 应用程序时收到此消息， bootstrap 完成后，我的日志中出现此异常。有人可以指导我在哪里寻找此异常的原因吗？它想表达什么？

Answer 1

没有任何源代码或您的版本 Grails ，看看你的异常堆栈跟踪，以下内容突出:

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 和以下 JIRA 问题进行了一些研究 GRAILS-8645与您具有相同的堆栈跟踪。查看有关此 JIRA 问题的堆栈跟踪。根据 JIRA 问题，它似乎影响了 Scaffolding在 2.0 final 中，但在 2.0.1 中修复。
