有可能是 pom 配置不对，导致 bean 被加载了两次。 或者是运行于 tomcat 环境， web.xml 配置不对，导致了 bean 被加载了两次。
可以看下这个 [starter 说明](https://docs.servicecomb.io/java-chassis/zh_CN/using-java-chassis-in-spring-boot/components-for-spring-boot/)，和对应的示例

问题原因之一：
@ImportResource(classpath*:META-INF/spring/*.bean.xml) 这个被重复声明了。
@EnableServiceComb里面声明了一次，产品自定义的注解又声明了一次，导致重复加载bean
