本文探讨了在使用Spring框架时遇到的冲突问题，导致使用Tomcat启动失败的情况。通过分析发现，Spring-asm包与自身内部类存在命名冲突。作者通过排除依赖并重新部署的方式解决了这一问题，确保了项目的正常运行。

项目POM 文件加入一个包后build没问题，Tomcat启动失败，后台报错如下。

Failed to read candidate component class ....
IncompatibleClassChangeError: class ClassMetadataReadingVisitor has interface ClassVisitor as super class

问题原因参见文章： http://www.cnblogs.com/taven/archive/2013/04/02/2994998.html
简言之就是 spring 的类 ClassMetadataReadingVisitor 继承了 ClassVisitor 抽象类，但是在spring-asm 包中有个同名的 ClassVisitor 接口。

问题解决：mvn dependency:tree 查看包依赖

可以看到对spring-asm.jar 的依赖，下面排除该依赖，重新部署，成功运行。 over
