如何部署tomcat7-maven-plugin？

Question

我想使用maven tomcat7:deploy部署一个项目。我使用的是maven 3.3.9，apache tomcat 7，OS X。

我在tomcat-users.xml中设置了用户和口令，在Maven settings.xml中设置了口令和用户。

我收到了这个错误消息：

Caused by: java.lang.ClassCastException: org.springframework.web.SpringServletContainerInitializer cannot be cast to javax.servlet.ServletContainerInitializer

意味着您已经构建了一个包含两个spring-web副本的环境:一个在您的webapp内，另一个在外面，并且某个东西正在将一个对象从一个传递到另一个。这可能意味着你需要去掉webapp内部的副本，这样它才能从外部继承类。
