how to get the ip and port of the client side for each packet of data on grpc server side which implement by java?

I want to get the client ip and port corresponding to each packet of data by java grpc service.

service Auxiliary {
  rpc ProcessMessage(AuxiliaryGrpcMsgRequest) returns (AuxiliaryGrpcMsgReply) {
  }
}

this method is generated by proto

public void processMessage( AuxiliaryGrpcMsgRequest request, 
           StreamObserver<AuxiliaryGrpcMsgReply> responseObserver) {

}

I want know corresponding IP and port of request . I used ServerInterceptor to get IP, but Interceptor thread is different with this processMessage thread. I don't want to use lock to synchronize the two threads, so I want to see if there is any way to get the ip and port of the client corresponding to the request directly in one thread

I noticed C++ can use context->peer() to achieve this.but java's context have no peer(), is there any way to slove this?

This information is available to interceptors via serverCall.getAttributes().get(Grpc.TRANSPORT_ATTR_REMOTE_ADDR). If you want it in the Context, you'd need to use a ServerInterceptor to copy it to the Context.
