简介： RabbitMQ学习笔记 04、Springboot集成RabbitMQ

springboot继承rabbitmq实操

生产者服务

此时我们通过使用springboot来快速搭建一个生产者服务

step1：引入依赖以及配置rabbitmq

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

application.yml

server:
  port: 8080
spring:
  application:
    name: producter
  rabbitmq:
    addresses: 192.168.118.128:5672
    username: admin
    password: password
    virtual-host: /
    connection-timeout: 15000

注意：对应的rabbitmq服务默认是跑在5672端口的，千万不要填15672，其是管理后台的端口号！！！

step2：定义队列、交换机以及绑定的routingkey

说明：该配置就相当于我们之前案例中在消费者的配置操作！！！

TopicRabbitConfig.java

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
 * @ClassName TopicRabbitConfig
 * @Author ChangLu
 * @Date 2021/9/25 13:37
 * @Description Topic类型交换机配置
 */
@Configuration
public class TopicRabbitConfig {
    //配置队列
    @Bean
    public Queue queue1(){
        return new Queue("queue1");
    }
    @Bean
    public Queue queue2(){
        return new Queue("queue2");
    }
    //配置交换机
    @Bean
    public TopicExchange exchange(){
        return new TopicExchange("bootExchange");
    }
    //绑定队列到交换机并且执行routingkey，之后指定消费者即可通过指定队列来拿到信息
    @Bean
    public Binding bindingExchangeMessage1(Queue queue1,TopicExchange exchange){
        return BindingBuilder.bind(queue1).to(exchange).with("cat.red");
    }
    @Bean
    public Binding bindingExchangeMessage2(Queue queue2,TopicExchange exchange){
        return BindingBuilder.bind(queue2).to(exchange).with("*.red");
    }
}

step3：编写发送方法并添加测试方法

MsgSender.java
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
/**
 * @ClassName MsgSender
 * @Author ChangLu
 * @Date 2021/9/25 13:42
 * @Description 发送消息到指定交换机
 */
@Component
public class MsgSender {
    @Autowired
    private AmqpTemplate amqpTemplate;
    private static String EXCHANGE_NAME = "bootExchange";
    //发送信息的routingkey=>"cat.red"
    public void send1(){
        String routingKey = "cat.red";
        String msg = "this is my message,routingkey is "+routingKey;
        //交换机名称、routingkey以及发送的信息
        amqpTemplate.convertAndSend(EXCHANGE_NAME,routingKey,msg);
        System.out.println("已成功发送信息："+msg);
    }
    //发送信息的routingkey=>"dog.red"
    public void send2(){
        String routingKey = "dog.red";
        String msg = "this is my message,routingkey is "+routingKey;
        //交换机名称、routingkey以及发送的信息
        amqpTemplate.convertAndSend(EXCHANGE_NAME,routingKey,msg);
        System.out.println("已成功发送信息："+msg);
    }
}

接着我们在测试类中进行两个方法调用：

mport com.changlu.productor.config.MsgSender;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class ProductorApplicationTests {
    @Autowired
    private MsgSender msgSender;
    @Test
    void sendMsg1() {
        msgSender.send1();
        msgSender.send2();
    }
}

消费者服务

step1：引入依赖以及配置rabbitmq

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

application.yml

server:
  port: 8081  # 设置8081端口，不要与生产者服务其冲突
spring:
  application:
    name: consumer
  rabbitmq:
    addresses: 192.168.118.128:5672  # 同样注意rabbitmq运行端口默认为5672
    username: admin
    password: password
    virtual-host: /
    connection-timeout: 15000

step2：定义消费者并进行绑定监听

消费者1：绑定对应的queue1

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
/**
 * @ClassName Consumer1
 * @Author ChangLu
 * @Date 2021/9/25 13:52
 * @Description queue1对应routingkey=>cat.red
 */
@Component
@RabbitListener(queues = "queue1")
public class Consumer1 {
    @RabbitHandler
    public void process(String msg){
        System.out.println("queue1收到消息："+msg);
    }
}

消费者2：绑定对应的queue2

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
/**
 * @ClassName Consumer1
 * @Author ChangLu
 * @Date 2021/9/25 13:52
 * @Description queue2对应routingkey=>*.red
 */
@Component
@RabbitListener(queues = "queue2")
public class Consumer2 {
    @RabbitHandler
    public void process(String msg){
        System.out.println("queue2收到消息："+msg);
    }
}
