Question

当我使用嵌入式tomcat 7启动我的应用程序localy时一切正常。但是当我使用tomcat7：redeploy（maven插件）部署到远程计算机时，我遇到了应用程序部分的问题。应用程序启动正常，部分工作正常，但是当我将XML包发送到应用程序时，它会抛出此异常：

两台机器上java的版本是相同的1.6.45，并且远程tomcat实例上只有这个webapp。我试着和赞同的目录一起玩，但没有成功。

Answer 1

这是根本原因：

我猜测JAR的Spring版本和Tomcat附带的版本之间存在冲突。 Tomcat的服务器类加载器首先找到它们的版本，并且没有Spring需要的方法。
