springboot整合activeMQ

上一篇，我们已经完成了对消息中间件的理解以及activeMQ的安装，现在我们来使用springboot整合activeMQ。

• 创建springboot生产者工程 （mq-producer）

1. 引入maven依赖
   完整的maven依赖如下：

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.4.RELEASE</version>
		<relativePath/><!-- lookup parent from repository -->
	</parent>
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
		</dependency>
		<!-- spring boot web支持：mvc,aop... -->
		<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-activemq</artifactId>
		</dependency>
	</dependencies>
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

2. 配置yml文件（注意：以下ip需要根据自己实际的ip地址进行修改）

spring:
  activemq:
    broker-url: tcp://192.168.10.11:61616
    user: admin
    password: admin

queue: com.itmayiedu  #队列名称

server:
  port: 8081

3. 创建QueueConfig

package com.itmayiedu.producer;

import javax.jms.Queue;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
 * 创建一个队列
 * @author DELL
 *
 */
@Configuration
public class QueueConfig {
	@Value(value = "${queue}")  //获取配置文件中的队列名称
	private String queue;

	@Bean   //注入bean
	public Queue logQueue() {
		return new ActiveMQQueue(queue);
	}

}

4. 创建Producer

package com.itmayiedu.producer;

import javax.jms.Queue;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
@EnableScheduling
public class Producer {
	@Autowired
	private JmsMessagingTemplate jmsMessagingTemplate;
	@Autowired
	private Queue queue;

	@Scheduled(fixedDelay = 5000)  //定时任务，每隔5秒钟执行一次
	public void send() {
		jmsMessagingTemplate.convertAndSend(queue, "测试消息队列" + System.currentTimeMillis());
	}
}

• 启动springboot项目，我们会发现每隔5秒钟就会在队列里面产生一条消息
  
  至此消息生产者工程已经搭建好了，接下来我们来搭建消息消费者工程。
• 创建springboot消费者工程 mq-consumer

1. 引入maven依赖
   完整的maven依赖如下：

<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.4.RELEASE</version>
		<relativePath/><!-- lookup parent from repository -->
	</parent>
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
		</dependency>
		<!-- spring boot web支持：mvc,aop... -->
		<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-activemq</artifactId>
		</dependency>
	</dependencies>
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

2. 配置yml文件

spring:
  activemq:
    broker-url: tcp://192.168.10.11:61616
    user: admin
    password: admin

queue: com.itmayiedu  #队列名称，与消息生产者的队列名称保持一致

3. 创建Consumer

package com.itmayiedu;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

@Component
public class Consumer {

	@JmsListener(destination = "${queue}")   //监听队列里面的消息
	public void receive(String msg) {
		System.out.println("监听器收到msg:" + msg);
	}

}

启动springboot项目，我们会发现消费者会收到生产者发出的消息，并对其消息进行消费，如下图：

通过以上步骤，我们已经完成了springboot对activeMQ的整合。
