一、ActiveMQ的单机安装

1、下载activeMq的tar安装包,如apache-activemq-5.15.0-bin.tar.gz

2、解压：tar -zxvf apache-activemq-5.15.0-bin.tar.gz

3、在bin目录下启动activemq： ./activemq start

4、在保证防火墙关闭或开启activemq的端口的情况下，在浏览器中访问：http://ip:port进行访问

port为conf/jetty.xml中查找/jettyPort,默认为8161

5、点击Manager ActiveMQ broker，输入默认的账号和密码，都是admin，登录成功

二、ActiveMQ的Java发送和接收消息

一般在工作中会使用Spring集成的方式进行消息的发送和接收，但是在这之前需要先使用Java客户端的方式进行发送。ActiveMq是JMS的实现，只有使用Java客户端的方式进行消息的发送和接收，这才能更好的理解JMS。当然ActiveMQ可以使用多种消息类型进行发送，Java客户端链接的时候一般创建连接是使用tcp方式，可以在安装目录的/conf/activemq/xml中查找/transportConnectors，如下：

并且需要在消息发送端和接收端都引入与安装的ActiveMQ相同的Java客户端（获取直接引入activemq-all）的版本，如下：

<!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-all -->
      <dependency>
          <groupId>org.apache.activemq</groupId>
          <artifactId>activemq-all</artifactId>
          <version>5.15.0</version>
      </dependency>

1、发送端（Provider）

package com.kevin.acticemq;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class JmsSender {

    public static void main(String[] args) {
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://192.168.1.103:61616");
        Connection connection = null;
        try {
            connection = connectionFactory.createConnection();
            connection.start();
            Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
            Destination destination = session.createQueue("queue-name-kevin");
            //
            MessageProducer producer = session.createProducer(destination);
            // 定义发送消息的类型   可以定义TextMessage，ObjectMessage...
            TextMessage textMessage = session.createTextMessage("hello,world!");
            session.createTextMessage()
            // 发送消息
            producer.send(textMessage);

            session.commit();
            session.close();
        } catch (JMSException e) {
            e.printStackTrace();
        } finally {
            if(connection != null) {
                try {
                    connection.close();
                } catch (JMSException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

2、接收端（Consumer）

package com.kevin.activemq;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class JmsConsumer {

    public static void main(String[] args) {
        ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://192.168.1.103:61616");
        Connection connection = null;
        try {
            connection = factory.createConnection();
            connection.start();
            Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
            Destination destination = session.createQueue("queue-name-kevin");
            MessageConsumer consumer = session.createConsumer(destination);
            TextMessage receive = TextMessage.class.cast(consumer.receive());
            String text = receive.getText();
            System.out.println(text);

            session.commit();
            session.close();
        } catch (JMSException e) {
            e.printStackTrace();
        } finally {
            if (connection != null) {
                try {
                    connection.close();
                } catch (JMSException e) {
                    e.printStackTrace();
                }
            }
        }

    }
}

三、ActiveMQ与Spring整合

需要在provider和Consumer中添加如下的maven依赖：

        <property name="maxConnections" value="50"/>
    </bean>
    <!-- 配置发送的目的地，指定发送queue的名称，没有会进行创建 -->
    <bean id="destination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg index="0" value="spring-queue"/>
    </bean>

    <!--<bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">

        <property name="messageConverter">
            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>
</beans>

发送端：

package com.kevin.acticemq;

import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

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

public class SpringJmsSender {

    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:spring-jms.xml");
        JmsTemplate jmsTemplate = JmsTemplate.class.cast(context.getBean("jmsTemplate"));
        // 发送消息
        jmsTemplate.send(new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {
                TextMessage textMessage = session.createTextMessage("helle, spring message");
                return textMessage;
            }
        });

    }
}

2、接收端

配置接收端spring-jms.xml

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

    <!-- 创建工程与直接使用Java方式一样 -->
    <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
        <property name="connectionFactory">
            <bean class="org.apache.activemq.ActiveMQConnectionFactory">
                <property name="brokerURL">
                    <value>tcp://192.168.1.103:61616</value>
                </property>
            </bean>
        </property>
        <property name="maxConnections" value="50"/>
    </bean>
    <!-- 配置发送的目的地，指定发送queue的名称，没有会进行创建 -->
    <bean id="destination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg index="0" value="spring-queue"/>
    </bean>

    <!--<bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg index="0" value="spring-topic"/>
    </bean>-->
    <!-- 配置模板 -->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="defaultDestination" ref="destination"/>
        <property name="messageConverter">
            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>

    <!-- 增加监听 -->
    <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="destination" ref="destination"/>
        <property name="messageListener" ref="messageListener"/>
    </bean>

    <bean id="messageListener" class="com.kevin.activemq.SpringJmsListener"/>
</beans>

阻塞的接收消息：

package com.kevin.activemq;

import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;

public class SpringJmsConsumer {

    public static void main(String[] args) {
        // 测试阻塞模式获取消息时需要注销掉spring-jms.xml中的监听
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:spring-jms.xml");
        JmsTemplate jmsTemplate = JmsTemplate.class.cast(context.getBean("jmsTemplate"));
        // 阻塞方式接收消息
        String testMessage = String.class.cast(jmsTemplate.receiveAndConvert());
        System.out.println(testMessage);
    }
}

异步监听的方式接收消息：

package com.kevin.activemq;

import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;

public class SpringJmsConsumer {
    public static void main(String[] args) {
        // 测试阻塞模式获取消息时需要注销掉spring-jms.xml中的监听
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:spring-jms.xml");
    }
}

package com.kevin.activemq;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

public class SpringJmsListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        try {
            String text = TextMessage.class.cast(message).getText();
            System.out.println(text);
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}
