一、docker安装mq

docker run \
 -e RABBITMQ_DEFAULT_USER=islunatic\
 -e RABBITMQ_DEFAULT_PASS=islunatic \
 -v mq-plugins:/plugins \
 --name mq \
 --hostname mq \
 -p 15672:15672 \
 -p 5672:5672 \
 --network fitzone-net\
 -d \
 rabbitmq

进入服务器打开15672和5672端口如果无法访问运行以下代码

#进入容器
docker exec -it myrabbitmq bash
#安装插件
rabbitmq-plugins enable rabbitmq_management

二、项目配置mq

spring:
  rabbitmq:
    host: islunatic.icu # 你的虚拟机IP
    port: 5672 # 端口
    virtual-host: / # 虚拟主机
    username: islunatic # 用户名
    password: islunatic # 密码

三、使用mq

1、首先在启动类上开启任务调度

2、生产者

java 复制代码

//注入rabbitmq
@Autowired
private RabbitTemplate rabbitTemplate;

//发送消息
rabbitTemplate.convertAndSend("amq.topic","pay.success",orders.getNumber);

3、消费者

java 复制代码

@Component
@RequiredArgsConstructor
public class PayListener {
    private final OrdersService ordersService;

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(name = "order.pay.queue", durable = "true"),
            exchange = @Exchange(name = "amq.topic", type = ExchangeTypes.TOPIC),
            key = "pay.success"
    ))
        public void listenPaySuccess(Long orderId){
        ordersService.markOrderPaySuccess(orderId);
    }
}
