activemq 支持mysql持久化 消息队列使用

目前官网上的5.x.x版本都不能下载，故使用4.1.2版本进行测试
下载地址

下载下来的包解压后为绿色版的，除了配置java_home环境变量，其他不需要安装，可以直接启动。

启动命令: sudo ./apache-activemq-path/bin/acticemq

修改配置文件支持对mysql数据库的支持，打开/apache-activemq-path/conf/activemq.xml

配置为如下

根据自己的数据库要素，修改配置文件中数据库连接部分

注意：这里一定要用这种模式 jdbcPersistenceAdapter ,这样持久化时跟数据库同步，不过会影响性能，但对于需要双击热备的系统，使用mysql主从模式，只好这样配置，防止数据丢失

重启下，开始使用代码测试队列，当然，需要把/apache-activemq-path/apache-activemq-4.1.2.jar先引入环境中

入列部分

ConnectionFactory connectionFactory;
// Connection ：JMS 客户端到JMS Provider 的连接
Connection connection = null;
// Session： 一个发送或接收消息的线程
Session session;
// Destination ：消息的目的地;消息发送给谁.
Destination destination;

connectionFactory = new ActiveMQConnectionFactory(
ActiveMQConnection.DEFAULT_USER,
ActiveMQConnection.DEFAULT_PASSWORD,
"tcp://localhost:61616");
try {
// 构造从工厂得到连接对象
connection = connectionFactory.createConnection();
// 启动
connection.start();
// 获取操作连接
session = connection.createSession(Boolean.FALSE,
Session.AUTO_ACKNOWLEDGE);
// 获取session0的queue
destination = session.createQueue("villasy-queue");
//消息生产者
MessageProducer msgProducer = session.createProducer(destination);
//设置持久化
msgProducer.setDeliveryMode(DeliveryMode.PERSISTENT);
TextMessage txtMsg = session.createTextMessage("发送消息:"+i);
msgProducer.send(txtMsg);
//session.commit();   //可要可不用
}
}

} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (null != connection)
connection.close();
} catch (Throwable ignore) {
}
}

读取队列内容

ConnectionFactory connectionFactory;
// Connection ：JMS 客户端到JMS Provider 的连接
Connection connection = null;
// Session： 一个发送或接收消息的线程
Session session;
// 消费者，消息接收者

// Destination ：消息的目的地;消息发送给谁.
Destination destination;

MessageConsumer consumer; connectionFactory = new ActiveMQConnectionFactory(
ActiveMQConnection.DEFAULT_USER,
ActiveMQConnection.DEFAULT_PASSWORD,
"tcp://localhost:61616");
try {
// 构造从工厂得到连接对象
connection = connectionFactory.createConnection(); // 启动
connection.start(); // 获取操作连接
session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE); // 获取session0的queue
destination = session.createQueue("villasy-queue");
consumer = session.createConsumer(destination);

TextMessage message = (TextMessage) consumer.receive(1000);  //这里的1000表示读取延迟1秒
if (null != message) {
System.out.println("收到消息" + message.getText())；
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (null != connection)
connection.close();
} catch (Throwable ignore) {
}
}
