05、RabbitMQ第一个Demo程序_rabbitmq的第一个项目-优快云博客

本文介绍了Spring Cloud整合RabbitMQ的项目创建与测试过程。先通过Spring Starter Project创建项目，将RabbitMQ加入依赖并配置相关属性。接着编写生产者、消费者和测试类，创建消息队列Bean等。最后给出输出结果，并可在浏览器查看消息队列情况。

二、创建项目：

1、File -> new -> spring starter project

2、将RabbitMQ加入项目依赖中：

3、配置rabbitmq相关的属性，在application.properties中，加入以下配置：

spring.application.name=spring-cloud-mq

spring.rabbitmq.host=192.168.1.3
spring.rabbitmq.port=5672
spring.rabbitmq.username=unam
spring.rabbitmq.password=pwd

二、编写生产者、消息者和测试类

1、创建配置QueueConfig类，创建消息队列Bean：

package com.fifi.mqdemo;

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

@Configuration
public class QueueConfig {
	@Bean
	public Queue createQueue() {
		return new Queue("test-mq");
	}
	
}

2、创建消息生产类（provider）:

package com.fifi.mqdemo;

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

@Component
public class Sender {
	
	@Autowired
	private AmqpTemplate rabbiTemplate;
	
	public void send(String msg) {
		this.rabbiTemplate.convertAndSend("test-mq", msg);
	}

}

3、创建消息消费类（cusumer)

package com.fifi.mqdemo;

import java.util.Date;

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

@Component
public class Receiver {
	
	@RabbitListener(queues= {"test-mq"})
	public void processMsg(String msg) {
		System.out.println("receiver time : "+new Date()+" , msg : "+msg);
	}
}

4、创建测试类：

package com.fifi.mqdemo;

import java.util.Date;

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 SpringBootMqTestApplicationTests {
	
	@Autowired
	private Sender sender;

	@Test
	public void contextLoads() {
		while(true)
		{
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			this.sender.send("hello time : "+new Date());
		}
	}

}

输出及结果：

receiver time : Sat May 04 15:46:39 CST 2019 , msg : hello time : Fri May 03 14:52:06 CST 2019
receiver time : Sat May 04 15:46:40 CST 2019 , msg : hello time : Sat May 04 15:46:40 CST 2019
receiver time : Sat May 04 15:46:41 CST 2019 , msg : hello time : Sat May 04 15:46:41 CST 2019
receiver time : Sat May 04 15:46:42 CST 2019 , msg : hello time : Sat May 04 15:46:42 CST 2019
receiver time : Sat May 04 15:46:43 CST 2019 , msg : hello time : Sat May 04 15:46:43 CST 2019
receiver time : Sat May 04 15:46:44 CST 2019 , msg : hello time : Sat May 04 15:46:44 CST 2019
receiver time : Sat May 04 15:46:45 CST 2019 , msg : hello time : Sat May 04 15:46:45 CST 2019
receiver time : Sat May 04 15:46:46 CST 2019 , msg : hello time : Sat May 04 15:46:46 CST 2019
receiver time : Sat May 04 15:46:47 CST 2019 , msg : hello time : Sat May 04 15:46:47 CST 2019
