延时

在交换器声明时添加 ==delayed=“true”==属性

<!--声明交换器 -->
	<rabbit:topic-exchange
		name="topic_spring_exchange" durable="true" auto-delete="false"
		auto-declare="true" declared-by="mqadmin" delayed="true">
		<!-- topic rounterKey绑定可以使用匹配符来绑定 -->
		<rabbit:bindings>
			<rabbit:binding pattern="#.topic.#"
				queue="topic_spring_queue"></rabbit:binding>
		</rabbit:bindings>
	</rabbit:topic-exchange>
发送者

设置延时属性 毫秒
messager.getMessageProperties().setDelay(5000);

AmqpTemplate amqpTemplate = applicationContext.getBean("amqpTemplate", AmqpTemplate.class);
		
		System.out.println("============topic message==============");
		//构建消息
		byte [] msgBytes = ("topic message test "+ new Date()).getBytes();
		Message messager = MessageBuilder.withBody(msgBytes)
        .setContentType(MessageProperties.TEXT_PLAIN.getContentType())
        .setMessageId(UUID.randomUUID().toString())
        .build();
		//延时5秒后发送
		messager.getMessageProperties().setDelay(5000);
		//发送消息
		amqpTemplate.convertAndSend(exchange, rountKey, messager);
		
		System.out.println("===发送结束===");
