介紹 Active MQ是個消息隊列管理器，用于通訊的中間件。現在由我來給大家介紹一下如何使用ActiveMQ測試小程序。

修改bin目錄下activemq.bat
在最后一行加入

set ACTIVEMQ_OPTS=-Xms1G -Xmx1G

保存后執行該bat文件
新建maven項目
pom文件中加入依賴

發送端程序

import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;import javax.jms.*;public class Send {   // private static final int SEND_NUMBER = 10;    public static void main(String[] args){        //ConnectionFactory:連接工廠，JMS用它創建連接        ConnectionFactory connectionFactory;        //Connection:JMS客戶端到JMS Provider的連接        Connection connection = null;        //Session:一個發送或接收消息的線程        Session session;        //Destination:消息的目的地；消息的接收者        Destination destination;        //MessageProducer:消息發送者        MessageProducer producer;        //TextMessage message;        //構造ConnectionFactory實例對象，此處采用ActiveMQ的實現jar        connectionFactory = new ActiveMQConnectionFactory(                ActiveMQConnection.DEFAULT_USER,                ActiveMQConnection.DEFAULT_PASSWORD,                "tcp://www.wjdn.net:61616"        );        try{            //構造從工廠得到連接對象            connection = connectionFactory.createConnection();                        //匯海            connection.start();                       //獲取操作連接            session = connection.createSession(Boolean.TRUE,                    Session.AUTO_ACKNOWLEDGE);                         //獲取session注意參數值test是一個服務器的queue,須在ActiveMQ的console配置            destination = session.createQueue("test");                        //得到發送者            producer = session.createProducer(destination);                        //設置不持久化，實際情況請根據項目決定            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);                        //構造消息，這里寫死了，項目就是參數，或者方法獲取            sendMessage(session,producer);            session.commit();        }catch (Exception e){            e.printStackTrace();        }finally {            try {                if(null != connection)                    connection.close();            }catch (Throwable ignore){}        }    }    public static void sendMessage(Session session, MessageProducer producer) throws Exception{            for (int i = 1; i <= 100000; i++){            TextMessage message = session.createTextMessage("今日天氣asda" + i)；//發送消息到目的地            System.out.println("發送:"+message.getText());            producer.send(message);        }    }}

接收端程序

import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;import javax.jms.*;public class revice {    public static void main(String[] args) {        ConnectionFactory connectionFactory;        Connection connection = null;        Session session;        Destination destination;        //接收者-消費者        MessageConsumer messageConsumer;        connectionFactory = new ActiveMQConnectionFactory(                ActiveMQConnectionFactory.DEFAULT_USER,                ActiveMQConnectionFactory.DEFAULT_PASSWORD, "tcp://www.wjdn.net:61616");                        try{            connection = connectionFactory.createConnection();            connection.start();            session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE);            destination = session.createQueue("test");            messageConsumer = session.createConsumer(destination);            while(true){                TextMessage message = (TextMessage) messageConsumer.receive(1000);                                if(null != message){                    System.out.println("收到:"+message.getText());                }else{                    break;                }                message.acknowledge();            }        }catch(Exception ex){            ex.printStackTrace();        }finally{            try{                if(null != connection){                    connection.close();                }            }catch(Throwable ig){            }        }    }}
