想了想，希望这样并不行，这是在dubbo客户端调用不一致用于grpc服务器的情况下，才需要SERVICE_NAME，如果是调用dubbo三重服务器，还是使用JAVA_SERVICE_NAME的

或者说，从最初grpc服务不会注册到注册中心考虑，判断没有走注册中心，是直连的，就用SERVICE_NAME，否则用JAVA_SERVICE_NAME

客户端来说，就不用考虑是否原生的grpc服务了，使用都是一样的。

   dubbo server做了兼容的,JAVA_SERVICE_NAME和SERVICE_NAME都可以,现在问题在dubbo 
client请求时用的是JAVA_SERVICE_NAME,导致server如果不是dubbo就会识别不出,所以只要把dubbo 
client也就是请求时改成SERVICE_NAME即可.
