最近发布了Grails版本2.4.1。修复的一个错误是恢复使用servlet版本2.5的能力。见https://jira.grails.org/browse/GRAILS-11466
我创建了一个新的grails应用程序。没有改变任何东西,我能够编译并运行它。当我将grails.servlet.version更改为“2.5”时,我能够编译但是当我运行它时,我得到了以下堆栈跟踪错误。
有没有人知道我是否需要更改其他设置才能让Grails 2.4.1在servlet 2.5容器上运行?具体来说,tomcat 6。

如果您在将版本更改为2.5之后没有在运行Grails之前执行grails clean
,则会发生此错误
当版本为3.0时,会发生什么?Grails会向类路径添加额外的依赖项,从而导致将新行为添加到已编译的类中。
如果您随后将版本更改为2.5并且只执行run-app
,则额外的依赖关系将消失,但新行为仍会编译到类中。执行clean
解决此问题。
