我正在构建一个cdc管道来通过maxwell读取mysql binlog并将它们放入kafka中，我的压缩类型在maxwell配置中是snappy。但是在我的spring项目的消费者端我收到了这个错误。

我的消费者绑定到匿名消费者组，而不是我指定的消费者组。

spring:
  cloud:
    stream:
      kafka:
        binder:
          brokers: localhost
          defaultBrokerPort: 9092
          zkNodes: localhost
          defaultZkPort: 2181
        bindings:
          inEvent:
            group: eventin
            destination: event
          outEvent:
            group: eventout
            destination: processevent

我的 Spring Boot 应用程序

@SpringBootApplication
@EnableBinding(EventStream.class)
public class ConsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConsumerApplication.class, args);
    }
    @StreamListener(value = "inEvent")
    public void getEvent(Event event){
        System.out.println(event.name);
    }
}

我的输入输出通道接口

public interface EventStream {
    @Input("inEvent")
    SubscribableChannel inEvent();
    @Output("outEvent")
    MessageChannel outEvent();
}
