你好，我这个项目之前写的时候，使用的dubbo 的jar有点老，兼容性有可能出问题，你先按照这个思路梳理一下： 1、先看下你本地的 jdk/jre版本，如果是jdk8，这里可能会出现该版本兼容性问题，切换tomcat的jdk版本到7试试看。 2、看报错Caused by: java.lang.NoClassDefFoundError: javassist/ClassPath 这里，有可能是该javassist 包没找到，或者是包版本有问题，可尝试下这篇文章 http://www.cnblogs.com/luodengxiong/p/5763427.html 检查操作一下。 我当时使用的环境是tomcat 7 + jdk 7，测试通过的。

谢谢，我引入javassist包后可以跑起来了， 之前看pom里没有引用这个包，所以看见网上相关解决方法就跳过了，后续还有问题，我自己再研究研究，辛苦了
