RabbitMq入门（二）SpringBoot中使用RabbitMq

pom

首先配置RabbitMq

创建消息队列

pom

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

首先配置RabbitMq

port：默认 5672

spring:
  rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest

创建消息队列

注意：Queue 是这个 org.springframework.amqp.core.Queue;

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

/**
 *   @ClassName QueueConfig
 *   @Description TODO
 *   @Author liguanhua
 *   @Date 2019-3-20 14:04
 *   @Version 1.0
 *   创建消息队列
 **/

@Configuration
public class QueueConfig {


    /**
     * 功能描述:
     * @param: 创建消息队列hello
     * @return:
     * @auther: liguanhua
     * @date: 2019-3-20 14:06
     */
    @Bean
    public Queue createQueue(){
        return new Queue("hello");
    }

}

创建消息发送者


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

/**
 *   @ClassName Sender
 *   @Description TODO
 *   @Author liguanhua
 *   @Date 2019-3-20 14:07
 *   @Version 1.0
 *   创建消息发送者
 **/
@Component
public class Sender {


    @Autowired
    private AmqpTemplate amqpTemplate;

    public void send(String msg){
        //消息发送到hello这个消息队列。发送的信息为 msg
        this.amqpTemplate.convertAndSend("hello",msg);
    }

}

创建消息接收者

通过监听器来监听消息队列是否有消息进来。

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

/**
 *   @ClassName Receiver
 *   @Description TODO
 *   @Author liguanhua
 *   @Date 2019-3-20 14:12
 *   @Version 1.0
 *   消息接收者
 **/

@Component
public class Receiver {

//    创建消息监听器
    @RabbitListener(queues="hello")
    public void process(String msg){
        System.out.println(msg);
    }

}

也可以将监听器放到类上

方法上带有@RabbitHandler的则处理消息

测试

import com.lgh.rabbit_mq.config.Sender;
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;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RabbitMqApplicationTests {

	@Autowired
	private Sender sender;

	@Test
	public void contextLoads() {
	}
	@Test
	public void queueTest() throws InterruptedException {
		
		while (true){
                    Thread.sleep(1000);
		    sender.send("你好");
                }
	}

}
