ActionMQ5.8.0 JMS實例 手把手詳細圖解

ActionMQ 是開源的JMS實現

1.下載ActiveMQ

去官方網站下載：http://activemq.apache.org/

2.運行ActiveMQ

解壓縮apache-activemq-5.5.1-bin.zip，然後雙擊apache-activemq-5.8.0\bin\activemq.bat運行ActiveMQ程序。

啓動ActiveMQ以後，登陸：http://localhost:8161/admin/，創建一個Queue，命名爲FirstQueue。如下圖

目錄結構如下：

運行在網頁中，它會讓你登錄用戶方可進入，默認的用戶名和密碼是admin，

3 . 測試
ActiveMQ默認使用的TCP連接端口是61616,通過查看該端口的信息可以測試ActiveMQ是否成功啓動
window環境運行  netstat -an|find "61616"

Class源代碼中可以看到

4.創建Eclipse JAVA項目並運行

創建project：ActiveMQ-5.8，並導入apache-activemq-5.8.0\lib目錄下需要用到的jar文件，項目結構如下圖所示：

若找不到相應的包，使用以下連接下載也行 http://repo1.maven.org/maven2/org/apache/activemq/activemq-rar/

3.1.Sender.java

    private static final int SEND_NUMBER = 5;

    public static void main(String[] args) {
        // ConnectionFactory ：連接工廠，JMS 用它創建連接
        ConnectionFactory connectionFactory;

        try {

            destination = session.createQueue("FirstQueue");
            // 得到消息生成者【發送者】
            producer = session.createProducer(destination);
            // 設置不持久化，此處學習，實際根據項目決定
            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
            // 構造消息，此處寫死，項目就是參數，或者方法獲取
            sendMessage(session, producer);
            session.commit();
        } catch (Exception e) {
            e.printStackTrace();

            }
        }
    }

    public static void sendMessage(Session session, MessageProducer producer)throws Exception {
        for (int i = 1; i <= SEND_NUMBER; i++) {

            // 發送消息到目的地方

            producer.send(message);
        }
    }
}

3.2.Receiver.java

package cn.jms;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;

public class Receiver {
    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;消息發送給誰.
        Destination destination;
        // 消費者，消息接收者
        MessageConsumer consumer;
        connectionFactory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, "tcp://localhost:61616");
        try {
            // 構造從工廠得到連接對象
            connection = connectionFactory.createConnection();
            // 啓動
            connection.start();
            // 獲取操作連接
            session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);
            // 獲取session注意參數值xingbo.xu-queue是一個服務器的queue，須在在ActiveMq的console配置
            destination = session.createQueue("FirstQueue");
            consumer = session.createConsumer(destination);
            while (true) {
                // 設置接收者接收消息的時間，爲了便於測試，這裏設定爲100s
                TextMessage message = (TextMessage) consumer.receive(100000);
                if (null != message) {
                    System.out.println("收到消息" + message.getText());
                } else {
                    break;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (null != connection)
                    connection.close();
            } catch (Throwable ignore) {
            }
        }
    }
}

4.注意事項

先啓動apache-activemq-5.8.0\bin\activemq.bat運行ActiveMQ程序。在運行main方法，否則回報連接失敗的錯誤，如下

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

5.測試過程

1、先運行Sender，輸出以下信息，若先運行Receiver則無輸出

發送消息：ActiveMq 發送的消息1
發送消息：ActiveMq 發送的消息2
發送消息：ActiveMq 發送的消息3
發送消息：ActiveMq 發送的消息4
發送消息：ActiveMq 發送的消息5

2、運行Receiver

收到消息ActiveMq 發送的消息1
收到消息ActiveMq 發送的消息2
收到消息ActiveMq 發送的消息3
收到消息ActiveMq 發送的消息4
收到消息ActiveMq 發送的消息5
