【RabbitMQ】 延时队列（delayed_message_exchange插件实现）
一、安装 rabbitmq_delayed_message_exchange 插件
- 官方下载地址：https://www.rabbitmq.com/community-plugins.html
(1) linux下直接安装：
注意：
rabbitMQ 中必须是Disc(磁盘型)类型的节点才可以安装延时队列插件, RAM(内存型)类型节点无法安装。
- 1.通过 rpm -qa|grep rabbit 命令查看当前linux是否安装RabbitMQ
[root@linux]# rpm -qa|grep rabbit
rabbitmq-server-3.6.5-1.noarch
- 2.通过 rpm -ql rabbitmq-server-3.6.5-1.noarch 查找RabbitMQ安装路径
[root@linux]# rpm -ql rabbitmq-server-3.6.5-1.noarch
/etc/logrotate.d/rabbitmq-server
/etc/rabbitmq
/etc/rc.d/init.d/rabbitmq-server
/usr/lib/ocf/resource.d/rabbitmq/rabbitmq-server
/usr/lib/ocf/resource.d/rabbitmq/rabbitmq-server-ha
/usr/lib/rabbitmq/bin/rabbitmq-defaults
/usr/lib/rabbitmq/bin/rabbitmq-env
/usr/lib/rabbitmq/bin/rabbitmq-plugins
...
- 3.先通过 rabbitmq-plugins list 查看已安装的插件列表
[root@linux]# rabbitmq-plugins list
Configured: E = explicitly enabled; e = implicitly enabled

- 4.进入 /rabbitmq/lib/rabbitmq_server-3.6.5/plugins 上传预下载好的 rabbitmq_delayed_message_exchange 插件(rabbitmq_delayed_message_exchange-20171201-3.7.x.ez)
- 5.启动插件 rabbitmq-plugins enable rabbitmq_delayed_message_exchange
- 6.重启RabbitMQ 使插件生效: service rabbitmq-server restart
(2) linux下 Docker 镜像中安装：
- 1.查看当前Docker容器中的镜像,找到RabbitMQ
- docker ps -a
[root@linux ~]# docker ps -a

- 2.预先上传rabbitmq_delayed_message_exchange-20171201-3.7.x.ez插件到Linux文件夹中
- 3.拷贝插件文件到rabbitMQ的Docker容器中
[root@linux ~]# docker cp rabbitmq_delayed_message_exchange-20171201-3.7.x.ez rabbitmq3.7.7:/plugins
- 3.进入rabbitMQ的Docker容器中docker exec -it rabbitmq3.7.7 bash
[root@linux ~]# docker exec -it rabbitmq3.7.7 bash
root@myRabbit:/#
- 4.查看插件列表 rabbitmq-plugins list
- 5.启用插件
rabbitmq-plugins enable rabbitmq_delayed_message_exchange
二、接入
- 配置x-delayed-type的交换机即可
// config
public static final String DELAYED_ROUTING_KEY = "delay.queue.job.delay.routingKey";
public static final String DELAYED_EXCHANGE_TYPE = "x-delayed-message";
@Bean
public CustomExchange customExchange() {
Map args = new HashMap<>(2);
args.put("x-delayed-type", "direct");
return new CustomExchange(DELAYED_EXCHANGE_NAME, DELAYED_EXCHANGE_TYPE, true, false, args);
}
// message body

}
public void sendXDelayMessage(DelayMessage delayMessage) {
sendMessage(DelayMessageMqConfig.DELAYED_EXCHANGE_NAME, DelayMessageMqConfig.DELAYED_ROUTING_KEY, delayMessage);
}
private void sendMessage(String exchangeName, String routingKey, DelayMessage message) {
rabbitTemplate.convertAndSend(exchangeName, routingKey, message.getMessage(),
messagePostProcessor -> {
MessageProperties messageProperties = messagePostProcessor.getMessageProperties();
messageProperties.setDeliveryMode(MessageDeliveryMode.PERSISTENT);
messageProperties.setExpiration(message.getExpiration());
messageProperties.setDelay(message.getDelay());
return messagePostProcessor;
}
);
}
}
