ActiveMQ搭建

下载

到ActiveMQ官网，找到下载点。

目前，

官网为http://activemq.apache.org/

Linux版本下载点之一为：http://apache.fayea.com/activemq/5.11.1/apache-activemq-5.11.1-bin.tar.gz

启动

下载到本机，并解压

wget http://apache.fayea.com/activemq/5.11.1/apache-activemq-5.11.1-bin.tar.gz

tar -xf ./apache-activemq-5.11.1-bin.tar.gz
wget http://apache.fayea.com/activemq/5.11.1/apache-activemq-5.11.1-bin.tar.gz

tar -xf ./apache-activemq-5.11.1-bin.tar.gz

启动（当然，由于依赖于JAVA，如果你没有安装JAVA，它会提醒你的，哈哈）

cd ./apache-activemq-5.11.1-bin/bin

./activemq start
cd ./apache-activemq-5.11.1-bin/bin

./activemq start

测试启动成功与否

ActiveMQ默认监听61616端口，查此端口看看是否成功启动

netstat -an|grep 61616
netstat -an|grep 61616

如果一切顺利，会看到如下日志

顺便，登录下管理员页面，看看有木有问题：

URL : http://10.0.0.109:8161/admin/

ACC/PWD : admin/admin

尝试基本消息功能

接下来，用简单的点对点测试消息发送、消息接收。

引入包：

  • activemq-client-5.11.1.jar
  • geronimo-j2ee-management_1.1_spec-1.0.1.jar
  • geronimo-jms_1.1_spec-1.1.1.jar
  • hawtbuf-1.11.jar
  • slf4j-api-1.7.10.jar

        Connection connection = factory.createConnection();

        connection.start();

        Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);

        Destination destination = session.createQueue("TestQueue");

        MessageProducer producer = session.createProducer(destination);

        producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

        ObjectMessage message = session.createObjectMessage("hello world...");

        producer.send(message);

        session.commit();

        System.out.println("sent...");

ActiveMQ搭建

看到console打印出：Receive : hello world...，可知接收到消息了，内流满面啊啊啊啊。。。

关闭

查询进程id（pid），禁止其进程：

ps -ef | grep activemq

kill -9 pid
ps -ef | grep activemq

kill -9 pid

再运行Sender，她就无法连接了，哈哈哈哈哈

Exception in thread "main" javax.jms.JMSException: Could not connect to broker URL: tcp://10.0.0.109:61616. Reason: java.net.ConnectException: Connection refused: connect
Exception in thread "main" javax.jms.JMSException: Could not connect to broker URL: tcp://10.0.0.109:61616. Reason: java.net.ConnectException: Connection refused: connect

好了，基本的搭建告一段落。

荆棘

过程中，遇到一个小问题，就是我一开始是用JDK1.6去跑的，报出常见的Unsupported major.minor version 51.0

针对这个问题，这个帖子有很好的参考意义：

http://www.cnblogs.com/chinafine/articles/1935748.html

找出jar中的一个class，执行以下命令，可查出minor version、major version：

javap -verbose yourClassName
javap -verbose yourClassName

或直接查看jar中的META-INF\MANIFEST.MF。

然后对照帖子中的JDK版本，换成JDK1.7就OK了。
