如何使用ActiveMQ測試小程式

介紹 Active MQ是個訊息佇列管理器，用於通訊的中間件。現在由我來跟大家介紹如何使用ActiveMQ測試小程式。

首先需要下載ActiveMQ,並修改記憶體

#修改bin目錄下activemq.bat
在最後一行加入

set ACTIVEMQ_OPTS=-Xms1G -Xmx1G

#儲存後執行該bat檔案
新maven專案
pom檔案中加入依賴

            <!--我的mq版本为5.9.0-->

發送端程式

   // private static final int SEND_NUMBER = 10;
    public static void main(String[] args){        //ConnectionFactory:连接工厂，JMS用它创建连接

            connection = connectionFactory.createConnection();        
                //启动
            connection.start();         
              //获取操作连接

                    Session.AUTO_ACKNOWLEDGE);

            destination = session.createQueue("test");           
             //得到发送者
            producer = session.createProducer(destination);          
              //设置不持久化，实际情况请根据项目决定
            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);      
                  //构造消息，这里写死了，项目就是参数，或者方法获取
            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("今日天气asda" + i)；//发送消息到目的地
            System.out.println("发送:"+message.getText());
            producer.send(message);
        }
    }

接收端程式

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-消费者
        MessageConsumer messageConsumer;
        connectionFactory = new ActiveMQConnectionFactory(
                ActiveMQConnectionFactory.DEFAULT_USER,
                ActiveMQConnectionFactory.DEFAULT_PASSWORD, "tcp://localhost: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){

            }
        }
    }
