我无法通过代码连接到本地运行的Kafka示例-我可以使用Kafka-Console-Producer和Kafka-Console-Consumer成功连接，但当我使用Kafka Java SDK并简单地使用Java Producer连接到并生成任何消息时，它会失败并出现以下错误：

[Producer clientId=producer-1] Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available.
[kafka-producer-network-thread | producer-1] WARN org.apache.kafka.clients.NetworkClient - [Producer clientId=producer-1] Bootstrap broker localhost:9092 (id: -1 rack: null) disconnected

不知道这是否重要，但我在Windows上使用WSL 2和Kafka 2.12-2.5.0来测试这一点。如何启用更详细的日志记录并调试它？
我的Producer代码的截图

Properties properties = new Properties();
properties.setProperty(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
properties.setProperty(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());
properties.setProperty(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());

ProducerRecord<String, String> record = new ProducerRecord<String, String>("first_topic","first_value");

KafkaProducer<String, String> kafkaProducer = new KafkaProducer<String, String>(properties);
kafkaProducer.send(record);
