ActiveMQ之整合spring

ActiveMQ可以轻松的与Spring进行整合，Spring提供了一系列的接口类，非常的好用！

比如异步消息数据、异步发送邮件、异步消息查询等

<dependency>
			<groupId>org.apache.activemq</groupId>
			<artifactId>activemq-all</artifactId>
			<version>5.11.1</version>
		</dependency>
		<dependency>
			<groupId>org.apache.activemq</groupId>
			<artifactId>activemq-pool</artifactId>
			<version>5.11.1</version>
		</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jms</artifactId>
<version>${spring.version}</version>
</dependency>

　　

先引入两个activeMQ的jar包，

然后进行spring-activemq进行配制：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.2.xsd"
	default-autowire="byName" default-lazy-init="false">

	<!-- 第三方MQ工厂: ConnectionFactory -->
	<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
		<!-- ActiveMQ Address -->
        <property name="brokerURL" value="${activemq.brokerURL}" />
        <property name="userName" value="${activemq.userName}"></property>
        <property name="password" value="${activemq.password}"></property>
	</bean>

    <!--
    	ActiveMQ为我们提供了一个PooledConnectionFactory，通过往里面注入一个ActiveMQConnectionFactory
    	可以用来将Connection、Session和MessageProducer池化，这样可以大大的减少我们的资源消耗,要依赖于 activemq-pool包
     -->
	<bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory">
		<property name="connectionFactory" ref="targetConnectionFactory" />
		<property name="maxConnections" value="${activemq.pool.maxConnections}" />
	</bean>

	<!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
	<bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
		<!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
		<property name="targetConnectionFactory" ref="pooledConnectionFactory" />
	</bean>

	<!-- Spring提供的JMS工具类，它可以进行消息发送、接收等 -->
	<!-- 队列模板 -->
	<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
	    <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->
	    <property name="connectionFactory" ref="connectionFactory"/>
	    <property name="defaultDestinationName" value="${activemq.queueName}"></property>
	</bean> 

</beans>

创建好第三方MQ工厂: ConnectionFactory

然后创建生产者MQProducer ：

package bhz.mq;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;

import bhz.entity.Mail;

import com.alibaba.fastjson.JSONObject;

/**
 * <B>系统名称：</B><BR>
 * <B>模块名称：</B><BR>
 * <B>中文类名：</B><BR>
 * <B>概要说明：</B><BR>
 * @author jxh
 */
@Service("mqProducer")
public class MQProducer {

	private JmsTemplate jmsTemplate;

	public JmsTemplate getJmsTemplate() {
		return jmsTemplate;
	}

	@Autowired
	public void setJmsTemplate(JmsTemplate jmsTemplate) {
		this.jmsTemplate = jmsTemplate;
	}

	/**
	 * <B>方法名称：</B>发送邮件信息对象<BR>
	 * <B>概要说明：</B>发送邮件信息对象<BR>
	 * @param mail
	 */
	public void sendMessage(final Mail mail) {
		jmsTemplate.send(new MessageCreator() {
			public Message createMessage(Session session) throws JMSException {
				return session.createTextMessage(JSONObject.toJSONString(mail));
			}
		});
	}

}

看一下mail实体类：

package bhz.entity;

public class Mail {

	/** 发件人 **/
	private String from;
	/** 收件人 **/
	private String to;
	/** 主题 **/
	private String subject;
	/** 邮件内容 **/
	private String content;

	public Mail(){}

	public Mail(String from, String to, String subject, String content) {
		super();
		this.from = from;
		this.to = to;
		this.subject = subject;
		this.content = content;
	}

	public String getFrom() {
		return from;
	}
	public void setFrom(String from) {
		this.from = from;
	}
	public String getTo() {
		return to;
	}
	public void setTo(String to) {
		this.to = to;
	}
	public String getSubject() {
		return subject;
	}
	public void setSubject(String subject) {
		this.subject = subject;
	}
	public String getContent() {
		return content;
	}
	public void setContent(String content) {
		this.content = content;
	}

}

　下面进行消息的发送，通过junit进行发送测试：

package bhz.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import bhz.entity.Mail;
import bhz.mq.MQProducer;

/**
 * <B>系统名称：</B><BR>
 * <B>模块名称：</B><BR>
 * <B>中文类名：</B><BR>
 * <B>概要说明：</B><BR>
 * @author jxh
 */
@ContextConfiguration(locations = {"classpath:spring-context.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
public class TestProducer {

	@Autowired
	private MQProducer mqProducer;

	@Test
	public void send(){
		Mail mail = new Mail();
		mail.setTo("174754613@qq.com");
		mail.setSubject("异步发送邮件");
		mail.setContent("Hi,This is a message!");

		this.mqProducer.sendMessage(mail);
		System.out.println("发送成功..");		

	}

}

下面看一下消费者的这个项目的配置activemq-consumer：

这个项目多一个config

## ActiveMQ Configuration
activemq.brokerURL=tcp\://192.168.1.200\:61616
activemq.userName=bhz
activemq.password=bhz
activemq.pool.maxConnections=10
#queueName
activemq.queueName=mailqueue

## SMTP Configuration
mail.host=smtp.163.com
##mail.port=21
mail.username=***@163.com
mail.password=
mail.smtp.auth=true
mail.smtp.timeout=30000
mail.default.from=***@163.com

看一下消费者的consumer的spring-activemq.xml

	</bean>
</beans>

因为要发送邮件，这边还有一个邮件的配置：

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

       http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.2.xsd">

	<!-- Spring提供的发送电子邮件的高级抽象类 -->
	<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="host" value="${mail.host}" />
		<property name="username" value="${mail.username}" />
		<property name="password" value="${mail.password}" />
		<property name="defaultEncoding" value="UTF-8"></property>
		<property name="javaMailProperties">
			<props>

			</props>
		</property>
	</bean>

	<bean id="simpleMailMessage" class="org.springframework.mail.SimpleMailMessage">
		<property name="from">
			<value>${mail.default.from}</value>
		</property>
	</bean>

	<!-- 配置线程池 -->
	<bean id="threadPool" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
		<!-- 线程池维护线程的最少数量 -->
		<property name="corePoolSize" value="5" />
		<!-- 线程池维护线程所允许的空闲时间 -->
		<property name="keepAliveSeconds" value="30000" />
		<!-- 线程池维护线程的最大数量 -->
		<property name="maxPoolSize" value="50" />
		<!-- 线程池所使用的缓冲队列 -->
		<property name="queueCapacity" value="100" />
	</bean>

</beans>

　mail实体类和前面一样，

看一下接收消息的Listener，

package bhz.mq;

import javax.jms.Destination;
import javax.jms.Message;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.listener.SessionAwareMessageListener;
import org.springframework.stereotype.Component;

import bhz.entity.Mail;
import bhz.service.MailService;

import com.alibaba.fastjson.JSONObject;

/**
 * <B>系统名称：</B><BR>
 * <B>模块名称：</B><BR>
 * <B>中文类名：</B><BR>
 * <B>概要说明：</B><BR>
 * @author jxh
 */
@Component
public class MailQueueMessageListener implements SessionAwareMessageListener<Message> {

	@Autowired
	private JmsTemplate jmsTemplate;
	@Autowired
	private Destination mailQueue;
	@Autowired
	private MailService mailService;

	public synchronized void onMessage(Message message, Session session) {
		try {
			TextMessage msg = (TextMessage) message;
			final String ms = msg.getText();
			System.out.println("收到消息：" + ms);
			//转换成相应的对象
			Mail mail = JSONObject.parseObject(ms, Mail.class);
			if (mail == null) {
				return;
			}
			try {
				//执行发送业务
				mailService.mailSend(mail);

			} catch (Exception e) {
				// 发送异常，重新放回队列
//				jmsTemplate.send(mailQueue, new MessageCreator() {
//					@Override
//					public Message createMessage(Session session) throws JMSException {
//						return session.createTextMessage(ms);
//					}
//				});
				e.printStackTrace();
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

最后调用发送邮件的service，进行邮件发送：

package bhz.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.stereotype.Service;

import bhz.entity.Mail;

@Service("mailService")
public class MailService {

	@Autowired
	private JavaMailSender mailSender;
	@Autowired
	private SimpleMailMessage simpleMailMessage;
	@Autowired
	private ThreadPoolTaskExecutor threadPool;

	/**
	 * <B>方法名称：</B>发送邮件<BR>
	 * <B>概要说明：</B>发送邮件<BR>
	 * @param mail
	 */
	public void mailSend(final Mail mail) {
		threadPool.execute(new Runnable() {
			public void run() {
				try {
					simpleMailMessage.setFrom(simpleMailMessage.getFrom());
					simpleMailMessage.setTo(mail.getTo());
					simpleMailMessage.setSubject(mail.getSubject());
					simpleMailMessage.setText(mail.getContent());
					mailSender.send(simpleMailMessage);
				} catch (MailException e) {
					e.printStackTrace();
					throw e;
				}
			}
		});
	}
}

　　邮件配置是指完成后，就可以正常发送邮件了，这就是通过activemq异步发送邮件。
