至 DEBUG 为包 org.springframework 和 org.codehaus.groovy 然后你将能够获得更多的细节。

但是在grails的情况下，有时它只会阻止tomcat，删除 work 和 temp 目录并再次启动tomcat。

I see a number of posts on the various problems folks have with troubleshooting this problem: ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException:

Is there a way to turn on debugging to isolate the problem?

Its complaining about "No such property: getOrg for class: groovy.lang.MetaClassImpl" but that's not directly one one of our classes, is there some way to get info that's relevant to our codebase?

In our case we had a Grails 1.2.1 app deployed and running just fine in Tomcat. We then stopped Tomcat to do a DB backup and then restarted the app. The same WAR with no environmental changes(i.e, no config file changes, etc.) now throws this error. We had observed this behavior intermittently previously as well, but restarting used to fix the prob.

In our development environment, the same app runs just fine with "grails prod run-app" as well as "grails prod run-war".

The stacktrace snippets:

If you set logging level to DEBUG for packages org.springframework and org.codehaus.groovy then you will be able to get more details.

But in case of grails sometimes it helps just to stop tomcat, remove work and temp directories and start tomcat again.
