在jetty上可以跑起来的项目，在tomcat上面无法跑起来，报以下错误：

百度加上Google了很多，最后找到了解决方法，其实这种问题就是你的jar冲突了，可以看看你引入的jar所依赖的其他jar和你直接引入的jar冲突了。通过修改pom.xml文件，将所依赖的低版本的jar去除即可，博主是由于dubbo本身自带spring.jar和自己通过pom.xml引入的spring文件想冲突。

基于Maven项目管理的解决办法：

1. 
2. 
   
3. 
4. 修改之后的pom文件如下：

 <dependency>
             <groupId>com.alibaba</groupId>
             <artifactId>dubbo</artifactId>
             <version>2.5.3</version>
             <exclusions>
                 <exclusion>
                     <artifactId>spring</artifactId>
                     <groupId>org.springframework</groupId>
                 </exclusion>
             </exclusions>
         </dependency>
