将应用程序升级到Grails 2后，JBoss部署错误

Question

我已经将Grails应用程序从1.3.6升级到2.1.1。 经过修复和整理后，运行应用程序可以正常工作（在大多数情况下，仍然存在一些已过时的问题要处理）。 战争的建立也没有错误。

但是，当我部署到JBoss（4.2.2）中时，与grails 1.3.6战争所做的相同，我得到此错误：

因此，是否认为这是战争中lib中的catalina类与jboss中已经存在的catalina类之间的碰撞？ 当它在1.3.6上运行正常时，是否已将其添加到2.1.1 grails tomcat插件中，并且可以从grails插件中排除子依赖项吗？

谢谢。

Answer 1

找到“解决方案”，以防万一其他人正在寻找。

如果我将插件的声明从application.properties移到BuildConfig.groovy，则错误消失。 我不确定它是否确实“修复”了它，或者它是否引起了tomcat插件的清理/重新安装（可能已将其清除），但是它消除了部署时的错误。

此后，我遇到了另一个错误，JBoss休眠库比Grails 2.1.1依赖项中的库更旧：

Caused by: java.lang.NoSuchMethodException: org.hibernate.validator.ClassValidator.   
(java.lang.Class, java.util.ResourceBundle, org.hibernate.validator.MessageInterpolator, 
java.util.Map, org.hibernate.annotations.common.reflection.ReflectionManager)

通过按照此处的指示告诉JBoss使用该应用程序的库而不是其自身的库，可以解决此问题。
