我有下面的docker compose yml，

version: '3.5'
services:

  zookeeper:
    container_name: kafka-zookeeper
    image: wurstmeister/zookeeper:3.4.6
    ports:
      - "2181:2181"
    networks:
      - my-network

  kafka:
    container_name: kafka-server
    image: wurstmeister/kafka:2.12-2.5.0
    ports:
      - "9092:9092"
    links:
      - zookeeper
    environment:
      KAFKA_LISTENERS: PLAINTEXT://:9092
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://127.0.0.1:9092
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    networks:
      - my-network
networks:
  my-network:
    driver: bridge

我参考了下面的参考资料，
https://github.com/wurstmeister/kafka-docker/wiki/connectivity
我的spring boot application.yml文件如下，

kafka:
  bootstrap:
    url: 127.0.0.1:9092

错误是，

[taKafkaProducer] org.apache.kafka.clients.NetworkClient   : [Producer clientId=SensorDataKafkaProducer] Connection to node -1 (/127.0.0.1:9092) could not be established. Broker may not be available.

我可以通过客户端工具连接Kafka，并查看侦听器的详细信息 127.0.0.1:9092 ```

配置有问题吗？
