JMS

一、Weblogic中配置JMS

JMS服务器的配置：服务－－消息传送－－JMS服务器－－新建－－（持久性存储：[新建存储－－类型：文件存储－－确定] 这些步骤可选）－－下一步－－目标： AdminServer－－完成（PocJMSServer）

JMS模块配置：新建－－下一步－－目标：AdminServer－－下一步－－完成（SystemModule-0）

连接工厂配置：点击SystemModule-0－－新建－－下一步－－完成

队列配置：点击SystemModule-0－－新建－－下一步－－新建子部署－－目标：PocJMSServer－－完成

二、JMS发送端方法（主要参考网上资料）

   publicvoid sendMessages(String data, String sqdzj, String jgdm) {
InitialContext ctx =null;
QueueConnectionFactoryqcf = null;
QueueConnection qc =null;
QueueSession qsess =null;
Queue q = null;
QueueSender qsndr =null;
TextMessage message =null;
String QCF_NAME ="VisaConnectionFaction";//连接工厂的jndi名称
String QUEUE_NAME = "InOutQueueData";//队列jndi名称
Hashtable properties =new Hashtable();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
     "weblogic.jndi.WLInitialContextFactory");
properties.put(Context.PROVIDER_URL, "t3://192.168.0.11:7001");
properties.put(Context.SECURITY_PRINCIPAL, "weblogic");//域的用户名
properties.put(Context.SECURITY_CREDENTIALS, "12345678");//域的登录密码
try {
ctx = newInitialContext(properties);
// createQueueConnectionFactory
qcf =(QueueConnectionFactory)ctx.lookup(QCF_NAME);
// createQueueConnection
qc =qcf.createQueueConnection();
// createQueueSession
qsess =qc.createQueueSession(false, 0);
// lookupQueue
q =(Queue)ctx.lookup(QUEUE_NAME);
// createQueueSender
qsndr =qsess.createSender(q);
// createTextMessage
message =qsess.createTextMessage();
// setmessage text in TextMessage
message.setText(data);//消息内容
if("14".equals(jgdm.substring(0, 2))) {
   message.setStringProperty("orgcode", "140000");//设置消息属性
   message.setStringProperty("sqdzj", sqdzj);

} else if("09".equals(jgdm.substring(0, 2))) {
   message.setStringProperty("orgcode", "090000");
   message.setStringProperty("sqdzj", sqdzj);
}else{

}
qsndr.send(message);
message =null;
qsndr.close();
qsndr =null;
q = null;
qsess.close();
qsess =null;
qc.close();
qc = null;
qcf =null;
ctx =null;
System.out.println("Cleaned up and done.SQDATA");

} catch (Exception ne) {

ne.printStackTrace(System.err);
System.exit(0);
}
//   return s;
}

三、接收消息

publicclass QueueReceiveSQData implements MessageListener {
public final static StringJNDI_FACTORY="weblogic.jndi.WLInitialContextFactory";//与发送端应用配置一致

public final static StringPROVIDER_URL="t3://192.168.0.11:7001";//发送端URL

public final static StringJMS_FACTORY="VisaConnectionFaction";//与发送端应用配置一致

public final static String QUEUEIO="InOutQueueData";//与发送端应用配置一致

private static QueueConnectionFactory qconFactory;

private static QueueConnection qcon;

private static QueueSession qsession;

private static QueueReceiver qreceiver;

private static Queue queue;

/**
* 入口方法
*/
public static void receiveMsg() throws Exception {
InitialContext ic = getInitialContext();
QueueReceiveSQData q = newQueueReceiveSQData();
q.inits(ic, QUEUEIO);
// // 当收到"quit"信息后，停止接收
//   synchronized(q) {
//    while (true) {
//    try {
//    q.wait();
//    } catch (InterruptedException ie){
//
//    }
//    }
// }
// qr.close();
}

/**
* 1、
* 通过JNDI查找ConnectionFactory。
* 通过JNDI查找一个或多个Destination。
*/
private static InitialContext getInitialContext() throwsNamingException {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,JNDI_FACTORY);
env.put(Context.PROVIDER_URL,PROVIDER_URL);
return new InitialContext(env);
}


public void inits(Context ctx, String queueName)
throws NamingException, JMSException{
qconFactory =(QueueConnectionFactory) ctx.lookup(JMS_FACTORY);
qcon =qconFactory.createQueueConnection();
qsession =qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
queue = (Queue)ctx.lookup(queueName);
qreceiver =qsession.createReceiver(queue);
qreceiver.setMessageListener(newQueueReceiveSQData());
qcon.start();
System.out.println("SQDATA");


}

public void onMessage(Message msg){

try {
StringmsgText;
if ((msg instanceofjavax.jms.TextMessage)) {
System.out.println("DATA:"+ ((TextMessage)msg).getText());
System.out.println("orgcode:"+(msg.getStringProperty("orgcode")));
   msgText = ((TextMessage)msg).getText();

}
//    if (msg instanceof TextMessage) {
//    msgText =((TextMessage)msg).getText();
//    } else {
//    msgText = msg.toString();
//    }
//    System.out.println("Message Received: "+ msgText );
//    // 当收到"quit"信息后，停止接收
//    if (msgText.equalsIgnoreCase("quit")) {
//    synchronized(this) {
//    quit =true;
//      this.notifyAll();
//    }
//    }
} catch (JMSException jmse) {
jmse.printStackTrace();
}
}

/**
* 4、消息对象关闭
*/
public static void close()throws JMSException {
if(qreceiver!=null){
qreceiver.close();
qsession.close();
qcon.close();
}
}

四、监听类

publicclass ContextListener implements ServletContextListener {
public ContextListener() {
super();
}

public void contextInitialized(ServletContextEventservletContextEvent) {
System.out.println("====接收JMS信息程序启动=====");
try {
QueueReceive.receiveMsg();
QueueReceiveSQ.receiveMsg();
QueueReceiveSQData.receiveMsg();
} catch (Exception e) {
e.printStackTrace();
}
}

public void contextDestroyed(ServletContextEventservletContextEvent) {
System.out.println("====接收JMS信息程序关闭=====");
try {
QueueReceive.close();
QueueReceiveSQ.close();
QueueReceiveSQData.close();
} catch (JMSException e) {
}
}
}

五、web.xml文件配置监听

<listener>
<listener-class>com.mgear.services.datamethod.ContextListener</listener-class>
</listener>

六、部署项目后，可以自动监听到队列的消息。
