• 【ActiveMQ】ActiveMQ在Windows的安装，以及点对点的消息发送案例

    公司最近会用MQ对某些业务进行处理，所以，这次我下载了apache-activemq-5.12.0-bin把玩下。

    基于练习方便需要，使用Windows的版本。

    参考的优秀文章：

    activemq的几种基本通信方式总结

    Winsdows下安装

    下载后得到zip文件，解压后用命令行启动即可使用，有两个问题需注意。

    1. 启动的文件根据不同的系统类型，也分为32位、64位，请选择自身系统的启动文件
    2. 目前的apache-activemq-5.12.0版本需要1.7的JDK运行
    D:greenapache-activemq-5.12.0inwin64activemq.bat

    启动后，可见如下类型的日志，即正常启动：

    默认情况下， activemq服务监听61616端口，如此端口被占用，会报错，请释放后再试。

    基于JMS的点对点队列，实现异步队列发送短信

    在点对点模式（P2P或point to point）中，消息发送方称为生产者（Producer），消息接收方称为消费者（Consumer）。而在发布订阅模式中，则分别为发布者、订阅者。

    系统需要给客户发送短信，一般来说，我们都是通过调用3大运营商的短信接口进行发送短信的。

    而在某些时候，比如春节，发送短信的人数特别多，所以接口变得堵塞，发送短信需时较久。我们不希望因发送短信堵塞应用程序，因此，我们想把发送短信的部分放到MQ，从而实现异步发送短信。（当然，在这种情况下，我们不关心发送短信是否成功。即，即使发送短信失败，在系统的界面并不提示用户）。

    以下只是学习例子，并不适应实际案例。

    消费者持续连接MQ服务器，接收消息，并实现发送短信的业务

    public static void main(String[] args) throws JMSException {
        ConnectionFactory factory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, 
                "tcp://127.0.0.1:61616");
        Connection connection = factory.createConnection();
        connection.start();
        Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
        Destination destination = session.createQueue("SendSMS");
        MessageConsumer consumer = session.createConsumer(destination);
        
        while (true) {
            ObjectMessage message = (ObjectMessage)consumer.receive();
            if (message != null) {
                HashMap<String, String> messageMap = (HashMap<String, String>)message.getObject();
                sendSMS(messageMap.get("mobile"), messageMap.get("message"));
            }
        }
    }
    
    public static void sendSMS(String mobile, String message) {
        System.out.println("Send SMS to : " + mobile + ", content : " + message);
        
        /* 模拟在繁忙时间发送短信需时15秒 */
        try {
            TimeUnit.SECONDS.sleep(15);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

    两个生产者，用于发送消息，调用消费者发送短信。两个生产者意在测试，他们的不同点仅在于短信文本。
