Sharing spring boot web netty container

When I use `spring-cloud-starter-zookeeper-discovery` that it depend on `spring-boot-starter-web`, it happens there are two netty contariners. There are two server port that one is server port default by springboot ,one is grpc.port.I want to retain one netty container, Could it be adopted?

Start by reproducing the setup with spring-cloud-starter-zookeeper-discovery and spring-boot-starter-web, then trace how the Spring Boot and gRPC Netty servers are created. Done means the integration can retain one Netty container rather than starting separate servers and ports.
