rabbitMq 快速入门

一、使用docker 安装 rabbitmq

1.在合适的位置创建 docker-compose.yml 文件

/local/docker/myCompose/rabbitMq
vim docker-compose.yml

version: "3.1"
  
services:
  rabbitmq:
    restart: always
    image: rabbitmq:management
    container_name: rabbitmq
    ports:
      - 5672:5672
      - 15672:15672
    environment:
      TZ: Asia/Shanghai
      RABBITMQ_DEFAULT_USER: rabbit
      RABBITMQ_DEFAULT_PASS: 111111
    volumes:
      - ./data:/var/lib/rabbitmq

2.使用 docker-compose 构建 docker 容器

docker-compose up -d

3.查看容器

docker ps

CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                                                                                                         NAMES
b7ec95c13eaa        rabbitmq:management   "docker-entrypoint.s…"   4 hours ago         Up 4 hours          4369/tcp, 5671/tcp, 0.0.0.0:5672->5672/tcp, 15671/tcp, 15691-15692/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp   rabbitmq

二、项目使用 rabbitmq

1.pom

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
 </dependency>

1.5 application.properties

spring.rabbitmq.host=172.16.104.217
spring.rabbitmq.port=5672
spring.rabbitmq.username=rabbit
spring.rabbitmq.password=111111

2.创建配置文件
note：是org.springframework.amqp.core.Queue的queue

import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class mqConfig {

	// 创建一个topic
    @Bean
    public Queue queue() {
        // topic:helloRabbit
        return new Queue("helloRabbit");
    }
    // 这里可以创建多个 topic
    
}

3.生产者

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class mqProvider {

    @Autowired
    private AmqpTemplate amqpTemplate;

    public void  send(String message){
        System.out.println("Provider:"+message);
        // topic:helloRabbit
        amqpTemplate.convertAndSend("helloRabbit",message);
    }

}

5.执行发送

@SpringBootTest(classes = RabbitmqApplication.class)
class RabbitmqApplicationTests {

    @Autowired
    mqProvider mqProvider;

    @Test
    void contextLoads() {
        for (int i = 0; i < 10; i++) {
            mqProvider.send("hello my rabbit");
        }
    }

mq的后台将会在这里看到有消息产生
后台地址：http://172.16.104.217:15672/（我的测试机）

6.消费者 就会收到 他订阅的topic 的消息

@Component
// topic:helloRabbit
@RabbitListener(queues = "helloRabbit")
public class mqConsumer {

    @RabbitHandler
    public void process(String message){
        System.out.println("Consumer:"+message);
    }
}
