        System.out.println("发送完成");
    }
}

接收消息

@Component
public class RabbitmqListener {

    @RabbitListeners({@RabbitListener(queues = "topicqueue")})
    public void reveiceMessage(String msg, Channel channel, Message message) {
        System.out.println(msg);
        System.out.println(channel);
        System.out.println(message);
