java - 如何调试 ContextLoader - 上下文初始化失败和 BeanCreationException

Question

我看到许多关于人们在解决此问题时遇到的各种问题的帖子:
错误 context.ContextLoader - 上下文初始化失败 org.springframework.beans.factory.BeanCreationException:

有没有办法打开调试来隔离问题？

它提示“ No such property: getOrg for class: groovy.lang.MetaClassImpl ”但这不是我们的类之一，有什么方法可以获取与我们的代码库相关的信息吗？

在我们的例子中，我们部署了一个 Grails 1.2.1 应用程序，并且在 Tomcat 中运行良好。然后我们停止 Tomcat 进行数据库备份，然后重新启动应用程序。没有环境更改(即没有配置文件更改等)的相同 WAR 现在会引发此错误。我们之前也间歇性地观察到这种行为，但重新启动用于修复问题。

在我们的开发环境中，同一个应用程序在“grails prod run-app”和“grails prod run-war”下运行得很好。

Answer 1

如果您将日志记录级别设置为 DEBUG用于包裹 org.springframework和 org.codehaus.groovy那么您将能够获得更多详细信息。

但在 grails 的情况下，有时它有助于停止 tomcat，删除 work和 temp目录并再次启动tomcat。
