我正在使用maven创建一个spring mvc应用程序。它使用WebApplicationInitializer进行初始化。现在我试图添加hibernate依赖。当我添加它时，WebApplicationInitializer的onStartup不会被调用。我正在使用tomcat 7.即使我删除了hibernate依赖项并更新项目，问题仍然存在。可能是什么问题？

我按照以下链接创建了tomcat服务器，现在运行正常。
http://websystique.com/misc/how-to-setup-tomcat-with-eclipse/
如果有人能解释这与仅仅创建一个tomcat服务器并运行它而不修改Location等有什么不同。？
更新
事实证明，在更新pom.xml并更新maven项目之后，eclipse会从类路径中删除maven依赖项...再次添加它们是正确的解决方案。
答案 1 :(得分：0)
对我来说，解决该问题的方法是删除项目的.classpath文件，然后将项目重新导入Eclipse。
答案 2 :(得分：0)
在Intellij中遇到了同样的问题。 IDE不会自动将jar文件复制到/WEB-INF/lib。需要在"File-->Project Structure --> Artifacts处做些事情。
