核心：解决web启动报错StandardWrapper.Throwable org.springframework.beans.factory.BeanCreationException
问题原因：dubbo运用中的服务端发布成功，但是在zookeeper中没有检测到服务；
解决思路：
- 1、检查在spring配置文件中，是否将对应的包加入扫描；
- 2、检查对应的注解有没有加上@service注解；
- 3、检测web.xml文件是否引入了spring的配置；
备注：我就是忘记了项目搭建时，忘记测试各个涉及的框架整合验证，导致当前的web.xml文件中弄丢了spring的配置（哭笑不得）；
教训：工作中搭建工程时一定要进行验证下各个部分整合，以免出现此种情形；
以下是异常代码：
