我在Sping Boot 应用程序中使用了一个Kafka生产者。

@Component
public class MessageProducer {

    @Value("${topic.name}")
    private String topic;

    @Autowired
    private KafkaTemplate<Integer, String> kafkaTemplate;

    public void produceMessage(String msg) {
        kafkaTemplate.send(topic, msg);
    }
}

字符串
我在Sping Boot 配置文件application.properties中配置了以下属性：

spring.kafka.bootstrap-servers=...
topic.name=...
security.protocol=SASL_SSL
sasl.mechanism=PLAIN
spring.kafka.properties.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="..." password="...";

当我调用produceMessage时，日志会不断填充这样的消息：

你需要在所有Kafka值前加上spring.kafka。参见文档。
另外，sasl.mechanism=PLAIN似乎与security.protocol=SASL_SSL相矛盾。你想要SASL_PLAINTEXT吗？
这个错误仅仅意味着引导服务器无法连接，生产者正在尝试连接到您的值broker-101-broker-109中的9个代理中的每一个。
这也可能意味着SASL配置错误（用户名/密码）。
由于您尝试使用SASL_SSL，这意味着您还需要设置spring.kafka.properties[ssl.key.password]，spring.kafka.properties[ssl.keystore.location]等值。
这也可能意味着advertised.listeners在您从客户端使用的连接协议的服务器端属性上不正确。
您应该尝试使用具有相同设置的kafka-console-producer来验证连接是否工作，然后再移动到Spring客户端。
这里有一个来自Confluent的关于Confluent Cloud或本地Kafka的Sping Boot 配置的教程。
