# 32.3.2 接收消息

当完成Apache Kafka的基础配置，任何的bean都可以标注为`@KafkaListener`，来创建一个监听器端点。如果没有定义`KafkaListenerContainerFactory`，一个默认的将会用定义在`spring.kafka.listener.*`里的键值自动配置。另外，如果定义了一个`RecordMessageConverter` bean，它会自动关联到默认的工厂。

下面的组件在`someTopic`主题上创建了一个监听器端点：

```java
@Component
public class MyBean {

    @KafkaListener(topics = "someTopic")
    public void processMessage(String content) {
        // ...
    }

}
```
