SpringBoot+RabbitMQ学习笔记（一）

一丶添加依赖

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

配置文件：application.properties

server.port=8883

spring.application.name=hello-world
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

 

二丶创建消息队列

package com.example.ampq;

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

/**
 * Author:aijiaxiang
 * Date:2020/4/26
 * Description:
 */
@Configuration
public class QueueConfig {
    /**
     * 创建队列
     * @return
     */
    @Bean
    public Queue createQueue(){
        return new Queue("hello-queue");
    }
}

三丶创建生产者

package com.example.ampq;

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

/**
 * Author:aijiaxiang
 * Date:2020/4/26
 * Description:发送消息
 */
@Component
public class Sender {

    @Autowired
    private AmqpTemplate amqpTemplate;

    /**
     * 发送消息的方法
     * @param msg
     */
    public void send(String msg){
        //向消息队列发送消息
        //参数1：队列名称
        //参数2：消息
        this.amqpTemplate.convertAndSend("hello-queue",msg);
 
    }
}

四丶创建消费者

package com.example.ampq;

import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * Author:aijiaxiang
 * Date:2020/4/26
 * Description:消息接收者
 */
@Component
public class Receiver {

    /**
     * 接收消息的方法，采用消息队列监听机制
     *
     * 使用 @RabbitListener 注解标记方法，当监听到队列 hello-queue 中有消息时则会进行接收并处理
     *
     * @param msg
     */
    @RabbitListener(queues = "hello-queue")
    public void process(String msg){
        System.out.println("receiver："+msg);
    }
}

五丶测试一波

package com.example.amqp;

import com.example.ampq.Sender;
import com.example.helloworld.HelloworldApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

/**
 * Author:aijiaxiang
 * Date:2020/4/26
 * Description:
 */
@RunWith(SpringRunner.class)
@SpringBootTest(classes = HelloworldApplication.class)
public class QueueTest {
    @Autowired
    private Sender sender;

    /**
     * 测试消息队列
     */
    @Test
    public void test1() throws InterruptedException {
        while (true){
            Thread.sleep(1000);
            sender.send("hello");
        }

    }

  
}
