SpringCloudStream配置Rabbitmq的延迟队列配置

前言

使用springCloudStream实现Rabbitmq的延迟队列主要在配置如何配置。

• Rabbitmq需要安装延迟队列插件
• 参考：安装延迟插件

              exchange-type: direct
              queue-name-group-only: true

生产者

streamBridge.send("faultDelayMessage-out-0", ttt);

消费者

@Component("faultDelayMessage")
public class FaultDelayMessage implements Consumer<Message<byte[]>> {
    @Override
    public void accept(Message<byte[]> s) {
        System.out.println(System.currentTimeMillis() + " sss: " + s);
    }
}
