分析原因：org.springframework.web.SpringServletContainerInitializer cannot be cast to javax.servlet.ServletContainerInitializer

明显的类型转换异常，因为在我使用的springmvc版本是4.2.4，此SpringServletContainerInitializer(spring-web-4.2.4.RELEASE.jar)是由jdk1.6编译生成的，而ServletContainerInitializer(javax.servlet-api-3.1.0.jar)是由jdk1.7编译生成的，所以产生了类型转换异常。

解决办法：换成JDK7
