Kafka日志出现“Dispatcherhasnosubscribersforchannel'employee-management-1.kafka-log-publisher'”错误提示。

1. 确保在应用中正确配置了 Kafka 的连接信息。
2. 确认应用中是否正确创建了 Kafka 主题，并正确设置了消费者。
3. 确认 Kafka 主题的名称是否正确，并且消费者是否订阅了相应主题。
4. 如果以上方法都没有解决问题，可能是由于消费者未正确连接到 Kafka 服务器。可以检查 Kafka 服务器的日志以确认连接是否成功并排除网络故障等影响。
5. 代码示例：

@SpringBootApplication @EnableKafka public class EmployeeManagementApplication {

public static void main(String[] args) {
    SpringApplication.run(EmployeeManagementApplication.class, args);
}
