java - Tomcat 7 上的 Spring 应用程序问题

Question

当我使用嵌入式 tomcat 7 在本地启动我的应用程序时，一切正常。但是当我使用 tomcat7:redeploy (maven 插件) 部署到远程机器时，我的应用程序部分出现了问题。应用程序启动正常并且部分工作正常，但是当我将 XML 包发送到应用程序时它抛出此异常:

两台机器上的java版本都是1.6.45，远程tomcat实例上只有这个webapp。我试着玩认可的目录，但没有成功。

Answer 1

这是根本原因:

我猜测 JAR 的 Spring 版本与 Tomcat 附带的版本之间存在冲突。 Tomcat 的服务器类加载器先找到自己的版本，没有 Spring 需要的方法。
