Spring Cloud Stream是一个用于构建消息驱动的微服务的框架,可以方便地与消息代理进行交互。RabbitMQ是一个开源的消息代理,具有高可靠性、可扩展性和灵活性的特点。
使用Spring Cloud Stream将RabbitMQ消息广播给所有监听器的步骤如下:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream-binder-rabbit</artifactId>
</dependency>
@EnableBinding
注解将其与消息通道绑定。@EnableBinding(Source.class)
public class MessageProducer {
private final Source source;
public MessageProducer(Source source) {
this.source = source;
}
public void sendMessage(String message) {
source.output().send(MessageBuilder.withPayload(message).build());
}
}
@EnableBinding
注解将其与消息通道绑定。@EnableBinding(Sink.class)
public class MessageConsumer {
@StreamListener(Sink.INPUT)
public void receiveMessage(String message) {
// 处理接收到的消息
}
}

output:
destination: <exchange_name>
content-type: application/json
input:
destination: <exchange_name>
content-type: application/json
sendMessage
方法广播消息给所有监听器。@Autowired
private MessageProducer producer;
public void broadcastMessage(String message) {
producer.sendMessage(message);
}
使用Spring Cloud Stream广播消息给所有监听器的优势是:
