如何在scala/java中通过本地套接字而不是inet创建GRPC服务

import io.grpc.{Server, ServerBuilder}
import io.grpc.stub.StreamObserver

// 导入生成的GRPC代码
import com.example.grpc.{GreeterGrpc, HelloRequest, HelloResponse}

// 实现GRPC服务
class GreeterImpl extends GreeterGrpc.Greeter {
  override def sayHello(request: HelloRequest, responseObserver: StreamObserver[HelloResponse]): Unit = {
    val name = request.getName
    val response = HelloResponse.newBuilder().setMessage(s"Hello, $name!").build()
    responseObserver.onNext(response)
    responseObserver.onCompleted()
  }
}

object HelloWorldServer {
  def main(args: Array[String]): Unit = {
    val server = ServerBuilder.forPort(50051) // 创建本地套接字并绑定到指定端口
      .addService(GreeterGrpc.bindService(new GreeterImpl, ExecutionContext.global)) // 将GRPC服务绑定到本地套接字
      .build()

    server.start() // 启动GRPC服务

    Runtime.getRuntime.addShutdownHook(new Thread() {
      override def run(): Unit = {
        server.shutdown()
      }
    })

    server.awaitTermination()
  }
}
