kafka启动报错：Connection to node -1 (localhost/127.0.0.1:9092) could not be established

[2022-02-25 15:14:49,439] WARN [Producer clientId=console-producer] Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)

命令用错了，新版本kafka启动，不再使用--broker-listr：
bin/kafka-console-producer.sh --broker-list localhost:9092  --topic topic1

应该是：
bin/kafka-console-producer.sh --bootstrap-server localhost:9092  --topic topic1

使用时需要注意新版本的变化。
