ACTIVEMQ Installation and use

Always want to summarize the message queue, just recently have time, just fiddling with a bit. preparatory work Download

First go to ACTIVEMQ website to download the application. Select the corresponding version and download the extract.
Then you can use the version of Windows that I downloaded this time. Start

Use CMD to enter the Apache-activemq-5.14.3\bin directory. Then run the ACTIVEMQ Start program to start. The program's console page access port is 8161. Enter the http://localhost:8161/admin/ Queues.jsp can see which queues are now available. The app's access port defaults to 61616. Queue Operations send messages

Package activemq;
Import org.apache.activemq.ActiveMQConnection;

Import Org.apache.activemq.ActiveMQConnectionFactory;

Import javax.jms.*;
 /** * Created on 2017/1/24.

    */public class Sender {private static final int send_number = 5;

        public static void Main (String[]args) {connectionfactory connectionfactory;

        Connection Connection = null;

        Session session;

        Destination Destination;

        MessageProducer producer; ConnectionFactory = new Activemqconnectionfactory (Activemqconnection.default_user, Activemqconnection.defa

        Ult_password, "tcp://localhost:61616");

            try {connection = connectionfactory.createconnection ();

            Connection.start ();

            Session = Connection.createsession (Boolean.true,session.auto_acknowledge);

            Destination = Session.createqueue ("Send2recv");

         Producer = Session.createproducer (destination);   Producer.setdeliverymode (deliverymode.non_persistent);


            TextMessage message = Session.createtextmessage ("This is Message");
            Producer.send (message);

            System.out.println (Message.gettext ());

        Session.commit ();
        } catch (JMSException e) {e.printstacktrace (); }finally {try {if (null!= connection) Connection.clos
            E ();
            } catch (JMSException e) {e.printstacktrace ();
 }



        }
    }



}

Receive Message

Package activemq;
Import org.apache.activemq.ActiveMQConnection;


Import Org.apache.activemq.ActiveMQConnectionFactory;

Import javax.jms.*;
 /** * Created on 2017/1/24.

        */public class Receiver {public static void main (String args[]) {connectionfactory connectionfactory;

        Connection Connection = null;

        Session session;

        Destination Destination;

        Messageconsumer consumer; ConnectionFactory = new Activemqconnectionfactory (Activemqconnection.default_user, Activemqconnection.defa

        Ult_password, "tcp://localhost:61616");

            try {connection = connectionfactory.createconnection ();

            Connection.start ();

            Session = Connection.createsession (Boolean.false, Session.auto_acknowledge);

            Destination = Session.createqueue ("Send2recv");

            Consumer = session.createconsumer (destination);
        while (true) {        TextMessage message = (textmessage) consumer.receive ();
                if (null!=message) {System.out.println ("Receive Message" +message.gettext ());
                } else {break;
        }}} catch (JMSException e) {e.printstacktrace (); } finally {try {if (null!=connection) Connection.clo
            SE ();
            } catch (JMSException e) {e.printstacktrace ();

 }
        }
    }
}

integration with spring projects

In the official tutorial, just let the introduction of a Activemq-all jar package on it. After the introduction of the program has not been able to get up. Said slf2j bound two, because the version is not the same as the conflict. The original in the Activemq-all package of Pom file, He has included many of the jars he needs to use. It is useless to use exclusion, finally, instead, use the following dependency, solve.

   <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jms< /artifactid>
      <version>${spring.version}</version>
    </dependency>
    < dependency>
      <groupId>org.apache.activemq</groupId>
      <artifactid>activemq-spring </artifactId>
      <version>5.10.0</version>
    </dependency>

Then there is the spring configuration file

    }
        }); }


}

Consumption queue

package com.xxx.ws.service;
Import Org.apache.activemq.command.ActiveMQObjectMessage;
Import Org.apache.log4j.LogManager;
Import Org.apache.log4j.Logger;
Import Org.springframework.jms.annotation.JmsListener;
Import Org.springframework.jms.core.JmsTemplate;
Import Org.springframework.messaging.converter.MessageConverter;
Import Org.springframework.messaging.handler.annotation.SendTo;

Import Org.springframework.stereotype.Service;
Import Javax.annotation.Resource;
Import javax.jms.JMSException;
Import Javax.jms.Message;

Import Javax.jms.MessageListener;
 /** * Created on 2017/1/24.

    */@Service public class Jmsmessagereceiver {private final Logger Logger = Logmanager.getlogger (This.getclass ());



    @Resource private Jmstemplate jmstemplate; @JmsListener (Destination = "send2recv")//@SendTo ("recv2send") public void OnMessage (String text) throws Jmsexcept
    Ion {System.out.println ("Received:" + text); }
}

This will enable the production and consumption of messages in the spring project.
