Activemq基础之消费者和生产者

一、开发环境

activemq官网http://activemq.apache.org/
下载版本http://activemq.apache.org/download-archives.html
最新版本：Apache ActiveMQ 5.15.0 Released posted on Jul 06, 2017
使用开发版本：apache-activemq-5.13.1
开发环境：win7 64bit eclipse Mars.2 Release (4.5.2)
下载版本解压后，直接运行/bin/win64/activemq.bat
启动后在浏览器运行：http://localhost:8161

二、生产端

使用jar包：activemq-all-5.13.1.jar
使用failover的url方式可以实现断线重连的机制

public final class ActiveMQServer {    /**     * icap使用log4j1.2-api-2.2过度到了log4j2     */    private static Logger log = LogManager.getLogger("com.znv.icap.activemq");    private static String url;    static {        url = "failover://(tcp://10.45.152.227:61616,tcp://10.45.152.228:61616,tcp://10.45.152.229:61616)?randomize=false&initialReconnectDelay=100&timeout=2000";        // url = "failover://("        // + PropertyHelper.getInstance().getValue("activemqUrl",        // "tcp://10.45.157.91:61616,tcp://10.45.157.92:61616,tcp://10.45.157.93:61616")        // + ")?randomize=false&initialReconnectDelay=100&timeout=2000";    }    private boolean transacted = false;    private int ackMode = Session.AUTO_ACKNOWLEDGE;    private ActiveMQConnectionFactory connectionFactory;    private Connection connection;    private Session session;    private Topic topic;    private MessageProducer producer;    private static ActiveMQServer instance = null;    private ActiveMQServer() {        try {            connectionFactory = new ActiveMQConnectionFactory(url);            connection = connectionFactory.createConnection();            connection.start();            session = connection.createSession(transacted, ackMode);            topic = session.createTopic("change_data_device_20170330");            ((ActiveMQConnection) connection).addTransportListener(new TransportListener() {                @Override                public void transportResumed() {                    System.out.println(" 重连");                }                @Override                public void transportInterupted() {                    System.out.println("断开");                }                @Override                public void onException(IOException error) {                    System.out.println("31");                }                @Override                public void onCommand(Object command) {                    System.out.println("41");                }            });        } catch (JMSException e) {            e.printStackTrace();        }    }    public static ActiveMQServer getInstance() {        if(instance == null){            synchronized (ActiveMQClient.class) {                if(instance == null){                    instance = new ActiveMQServer();                }            }        }        return instance;    }    public void send(String msg) throws JMSException, InterruptedException {        producer = session.createProducer(topic);        TextMessage message = session.createTextMessage(msg);        producer.send(message);    }    public void close() {        if (producer != null) {            try {                producer.close();            } catch (JMSException e) {                log.error(e);            }        }        if (session != null) {            try {                session.close();            } catch (JMSException e) {                log.error(e);            }        }        if (connection != null) {            try {                connection.close();            } catch (JMSException e) {                log.error(e);            }        }    }    public Topic getTopic() {        return topic;    }    public void setTopic(Topic topic) {        this.topic = topic;    }    public static void main(String[] args) throws JMSException {        try {            JSONObject obj = new JSONObject();            obj.put("sessionId", "3D6FCF9B88AFF644848670F4DD9D0ACB");            obj.put("userId", "11000000000");            obj.put("deviceId", "11000010200080");            obj.put("type", "1");            String msg = obj.toJSONString();            ActiveMQServer.getInstance().send(msg);        } catch (InterruptedException e) {            e.printStackTrace();        }    }}

5.9的版本不能实现断线重连，需要重写
org.apache.activemq.transport.failover.FailoverTransport.java
activemq-all-5.9.0.jar

三、消费端

public final class ActiveMQClient implements MessageListener {    /**     * icap使用log4j1.2-api-2.2过度到了log4j2     */    private static Logger log = LogManager.getLogger("com.znv.icap.activemq");    private static String url;    static {        //10.45.146.180-182        url = "failover://(tcp://lv180.dct-znv.com:61616,tcp://lv181.dct-znv.com:61616,tcp://lv182.dct-znv.com:61616)?randomize=false&initialReconnectDelay=100&timeout=2000";        //10.45.152.227 lv03.dct-znv.com        url = "failover://(tcp://10.45.152.227:61616)?randomize=false&initialReconnectDelay=100&timeout=2000";    }    private boolean transacted = false;    private int ackMode = Session.AUTO_ACKNOWLEDGE;    private ActiveMQConnectionFactory connectionFactory;    private Connection connection;    private Session session;    private MessageConsumer consumer;    private static ActiveMQClient instance = null;    private ActiveMQClient() {        try {            connectionFactory = new ActiveMQConnectionFactory(url);            connection = connectionFactory.createConnection();            connection.start();            session = connection.createSession(transacted, ackMode);            Topic destination = session                .createTopic("change_report_20170330");            consumer = session.createConsumer(destination);            consumer.setMessageListener(this);            ((ActiveMQConnection) connection).addTransportListener(new TransportListener() {                @Override                public void transportResumed() {                    log.info("activemq resumed");                }                @Override                public void transportInterupted() {                    log.info("activemq interupted");                }                @Override                public void onException(IOException error) {                    log.error("activemq onException");                }                @Override                public void onCommand(Object command) {                    log.debug("activemq onCommand");                }            });        } catch (JMSException e) {            log.error(e);        }    }    public static ActiveMQClient getInstance() {        if (instance == null) {            synchronized (ActiveMQClient.class) {                if (instance == null) {                    instance = new ActiveMQClient();                }            }        }        return instance;    }    @Override    public void onMessage(Message message) {        try {            TextMessage txtmessage = (TextMessage) message;            log.error("=======================receive message from little v:"                + txtmessage.getText());//            ThreadPoolUtils.exec(new DealChangeDataThread(txtmessage.getText()));        } catch (JMSException e) {            log.error(e);        }    }    public void close() {        if (consumer != null) {            try {                consumer.close();            } catch (JMSException e) {                log.error(e);            }        }        if (session != null) {            try {                session.close();            } catch (JMSException e) {                log.error(e);            }        }        if (connection != null) {            try {                connection.close();            } catch (JMSException e) {                log.error(e);            }        }    }    public static void main(String[] args) {        ActiveMQClient.getInstance();    }}
