ActiveMQ Introductory Usage Examples

1. Download ACTIVEMQ

Go to official website download: http://activemq.apache.org/download-archives.html

2. Running ACTIVEMQ

Unzip Apache-activemq-5.9.0-bin.zip, and then double-click Apache-activemq-5.9.0\bin\activemq.bat to run the ACTIVEMQ program.

3. Create a project and run it in eclipse

If you are using a Maven project, configure it in Pom.xml

<dependency>  <groupId>org.apache.activemq</groupId>  <artifactid>activemq-all </artifactId>  <version>5.9.0</version></dependency>

or create a project directly, import Activemq-all-5.9.0.jar, and its log dependency package

4. Create a message queue

Consumer.java

Package Com.panie.mq.queue;import Java.util.date;import Javax.jms.connection;import javax.jms.ConnectionFactory; Import Javax.jms.destination;import javax.jms.jmsexception;import javax.jms.mapmessage;import javax.jms.Message; Import Javax.jms.messageconsumer;import Javax.jms.messagelistener;import Javax.jms.messageproducer;import Javax.jms.session;import Org.apache.activemq.activemqconnection;import        Org.apache.activemq.activemqconnectionfactory;public class consumer{public static void Main (string[] args) {        String user = Activemqconnection.default_user;        String password = Activemqconnection.default_password;        String url = activemqconnection.default_broker_url; String subject = "TOOL.                DEFAULT ";                ConnectionFactory connectionfactory = new activemqconnectionfactory (user, password, URL);            try {Connection Connection = connectionfactory.createconnection ();            Connection.start (); Final Session Session = connection.createsession (boolean.true, Session.auto_acknowledge);            Destination Destination = Session.createqueue (subject);            Messageconsumer consumer = session.createconsumer (destination); Consumer.setmessagelistener (New MessageListener () {@Override Pub                    LIC void OnMessage (Message msg) {Mapmessage message = (mapmessage) msg;                    Date date = new Date ();                        try {System.out.println ("---received message:" +new Date (Message.getlong ("Count"));                    Session.commit ();                         } catch (JMSException e) {//TODO auto-generated catch block                    E.printstacktrace ();            }                }            });            Thread.Sleep (10000);            Session.close ();   Connection.close ();     } catch (Exception e) {//TODO auto-generated catch block E.printstacktrace (); }    }        }

　　

Producer.java

Package Com.panie.mq.queue;import Java.util.date;import Javax.jms.connection;import javax.jms.ConnectionFactory; Import Javax.jms.destination;import Javax.jms.jmsexception;import Javax.jms.mapmessage;import Javax.jms.messageproducer;import Javax.jms.session;import Org.apache.activemq.activemqconnection;import        Org.apache.activemq.activemqconnectionfactory;public class producer{public static void Main (string[] args) {        String user = Activemqconnection.default_user;        String password = Activemqconnection.default_password;        String url = activemqconnection.default_broker_url; String subject = "TOOL.                DEFAULT ";                ConnectionFactory connectionfactory = new activemqconnectionfactory (user, password, URL);            try {Connection Connection = connectionfactory.createconnection ();            Connection.start ();            Session session = Connection.createsession (Boolean.true, Session.auto_acknowledge); Destination destInation = Session.createqueue (subject);            MessageProducer producer = Session.createproducer (destination);                for (int i=0;i<=20;i++) {Mapmessage message = Session.createmapmessage ();                Date date = new Date ();                Message.setlong ("Count", Date.gettime ());                Thread.Sleep (1000);                Producer.send (message);            System.out.println ("--Send Message:" +date);            } session.commit ();            Session.close ();        Connection.close ();        } catch (Exception e) {//TODO auto-generated catch block E.printstacktrace (); }    }        }

　　

Running these two methods, you can see in the console that the consumer output the message generated by the Producter
