I also have the same problem, when i change the dubbo's version from 2.7.0 to 2.7.1 （because the dubbo-2.7.0 has a bug "incubator-dubbo/issues/3555" which be fix on 2.7.1）,then i think maybe the dubbo-starter shuld be alse 2.7.1, but i cannot use the dubbo-starter-2.7.1(the dependency will not be found)

Did you try to add property spring.properties set spring.main.allow-bean-definition-overriding=true ?
