将Sun的Open Message Queue与Spring集成
1. 前言
基于JMS标准的消息中间件实现的产品有很多，JBossMQ、ActiveMQ、OpenMQ、OpenJMS等等，最常用的还是apache的ActiveMQ。有时也使用Sun的OpenMQ。在官网http://mq.java.net/处可以下载。Open Message Queue是Sun Java System Message Queue的一个开源版本。Open message queue是一个企业级，可升级，非常成熟的消息服务器。它为面向消息的系统集成提供一套完整的JMS（Java Message Service ）实现。由于Open MQ源自Sun的Java Message Queue，所以其具有Java System Message Queue拥有的所有特性，功能和性能。
2. 环境配置
下载后将相关的jar拷贝到项目的classpath下面。笔者在此为了安全起见，引入了很多jar包，将语言包都引入了。各位读者可以因地制宜。
以下是引入jar包的列表
lib/openmqjar/common-message.jar lib/openmqjar/fscontext.jar lib/openmqjar/grizzly.jar lib/openmqjar/imq_de.jar lib/openmqjar/imq_es.jar lib/openmqjar/imq_fr.jar lib/openmqjar/imq_it.jar lib/openmqjar/imq_ja.jar lib/openmqjar/imq_ko.jar lib/openmqjar/imq_pt_BR.jar lib/openmqjar/imq_zh_CN.jar lib/openmqjar/imq_zh_TW.jar lib/openmqjar/imq.jar lib/openmqjar/imqadmin.jar lib/openmqjar/imqbridgemgr.jar lib/openmqjar/imqbroker.jar lib/openmqjar/imqjmsbridge.jar lib/openmqjar/imqjmsra.rar lib/openmqjar/imqjmx_de.jar lib/openmqjar/imqjmx_es.jar lib/openmqjar/imqjmx_fr.jar lib/openmqjar/imqjmx_it.jar lib/openmqjar/imqjmx_ja.jar lib/openmqjar/imqjmx_ko.jar lib/openmqjar/imqjmx_pt_BR.jar lib/openmqjar/imqjmx_zh_CN.jar lib/openmqjar/imqjmx_zh_TW.jar lib/openmqjar/imqjmx.jar lib/openmqjar/imql10n_server_de.jar lib/openmqjar/imql10n_server_es.jar lib/openmqjar/imql10n_server_fr.jar lib/openmqjar/imql10n_server_it.jar lib/openmqjar/imql10n_server_ja.jar lib/openmqjar/imql10n_server_ko.jar lib/openmqjar/imql10n_server_pt_BR.jar lib/openmqjar/imql10n_server_zh_CN.jar lib/openmqjar/imql10n_server_zh_TW.jar lib/openmqjar/imqservlet.jar lib/openmqjar/imqstomp.jar lib/openmqjar/imqutil.jar lib/openmqjar/imqxm.jar lib/openmqjar/jaxm-api.jar lib/openmqjar/jhall.jar lib/openmqjar/jms.jar lib/openmqjar/jta.jar lib/openmqjar/protobuf-2.3.0.jar
3. 之后项目加入Spring的相关jar包。
增加Spring配置文件内容如下：
<?xml version="1.0" encoding="UTF-8"?>

factory-method="createConnectionFactory" />
<!--设置广发消息目的-->
<bean id="updateLocalRouteMap" class="com.sun.messaging.Topic">

</bean>

</property>
</bean>

<property name="transactionTimeout" value="180000" />
<property name="receiveTimeout" value="180000" />
<property name="sessionTransacted" value="true" />
</bean>
</beans>
4. 消息监听器
类代码如下
/**
* JMS消息消费者。
* 接收JMS消息后获得router想要的消息后，调用router接口更新本地缓存
* @author liuyan
*
*/
public class JMSMessageListener implements MessageListener {
private Logger log = Logger.getLogger(JMSMessageListener.class.getName());
/**
* 接收JMS消息后的业务处理
*/
public void onMessage(Message message) {
log.info("接收消息……");
byte[] byteMessage = JMSByteConverterUtil
.ConverterMessageToBttes(message);
try {
log.info("将转型成实体对象……");
//……………………………………………………
}
} catch (InvalidProtocolBufferException e) {
log.error("JMS异常" + e.getMessage());
e.printStackTrace();
} catch (Exception e) {
log.error("其他异常" + e.getMessage());
e.printStackTrace();
}
}
}
因为一些原因此处就不给出完整代码了~~~反正是获取一个字节流后，转成对象，直接从对象中获取想要的信息。转成对象的辅助类如下
/**
* 对获得的消息对象进行转型
* @author liuyan
*/
public class JMSByteConverterUtil {
private static Logger log = Logger.getLogger(JMSMessageListener.class
.getName());
/**
* 对获得的消息对象进行转型
* @param message
* @return
*/
public static byte[] ConverterMessageToBttes(Message message) {
if (message == null) {
log.error("消息对象为空……");
return null;
} else if (message instanceof BytesMessage) {
log.debug("消息强制转型BytesMessage");
BytesMessage bytesMessage = (BytesMessage) message;
byte[] messageBytes;
try {
log.debug("建立空的消息二进制数组");
messageBytes = new byte[(int) bytesMessage.getBodyLength()];
log.debug("往二进制数组中写进二进制信息");
bytesMessage.readBytes(messageBytes);
log.debug("messageBytes.length=" + messageBytes.length);
return messageBytes;
} catch (JMSException e) {
log.error("JMS错误：" + e.getMessage());
e.printStackTrace();
return null;
}
}else{
log.error("消息对象不能正确转型");
return null;
}
}
}
5. 启动消息监听器
开启OpenMQ的服务，启动{OpenMQ_HOME}\mq\bin\下的imqcmd.exe命令
启动消息消费者很简单，代码如下
public class MessageConsumer {
/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
new String[] { "classpath:/spring/applicationContext-openmq-jms.xml" });
System.out.println(applicationContext.getId());
}
}
6. 消息发送者
启动消息消费者服务后，写一个测试类测试一下消息的，代码如下
public class MessageSender {
/**
* @param args
* @throws JMSException
*/
public static void main(String[] args) throws JMSException {
ConnectionFactory myConnFactory;
myConnFactory = new com.sun.messaging.ConnectionFactory();
myConnFactory.setProperty(ConnectionConfiguration.imqAddressList,
"mq://127.0.0.1:7676");
myConnFactory.setProperty(ConnectionConfiguration.imqReconnectEnabled,
"true");
Connection myConn = myConnFactory.createConnection();
myConn.start();
// Step 4:
// Create a session within the connection.
Session mySess = myConn.createSession(false, Session.AUTO_ACKNOWLEDGE);
Topic myTopic = new com.sun.messaging.Topic("testmq");// .Queue("testmq");
MessageProducer myMsgProducer = mySess.createProducer(myTopic);
ObjectMessage objectMessage = mySess.createObjectMessage();
RouterMessageBean routerMessageBean = new RouterMessageBean();
routerMessageBean.setDbName("mysql-test");
routerMessageBean.setUserName("liuyan");
routerMessageBean.setMaster(null);
routerMessageBean.setSlave(null);
objectMessage.setObject(routerMessageBean);
BytesMessage bytesMessage = mySess.createBytesMessage();
bytesMessage.writeUTF("the message is 消息内容！");
myMsgProducer.send(bytesMessage);
System.out.println("测试发送JMS消息");
mySess.close();
myConn.close();
}
}
