• jboss jms 实例

      最近温习了下EJB和JMS，整理了下思路，和大家分享下P2P和Pub/Sub的demo ；JBoss 7 集成了HornetQ，JMS可以在HornetQ中间件运行，有时间在和大家分享关于HornetQ的文章。 

    1.下载Jboss 7并配置运行环境 http://www.jboss.org/jbossas/downloads 
    2.增加testjms用户（用以jms链接时使用），在jboss的bin目录下运行add-user.bat，如下： guest 一定要写。 
     
    3.修改启动配置文件，使用standalone-full.xml启动jboss服务器 
    Cmd代码  收藏代码
    1. $JBOSS_HOME$in>standalone.bat --server-config=standalone-full.xml  

    4.例子：修改Jboss配置文件standalone-full.xml，找到hornetq-server节点，在该节点下的jms-destinations确定含有以下配置： 
    Xml代码  收藏代码
    1. <jms-destinations>  
    2.                     <jms-queue name="testQueue">  
    3.                         <entry name="queue/test"/>  
    4.                         <entry name="java:jboss/exported/jms/queue/test"/>  
    5.                     </jms-queue>  
    6.                     <jms-topic name="ServerNotificationTopic">  
    7.                         <entry name="topic/ServerNotification"/>  
    8.                         <entry name="java:jboss/exported/jms/topic/ServerNotification"/>  
    9.                     </jms-topic>  
    10.                 </jms-destinations>  

    客户端项目用eclipse集成jboss的 j2ee项目。runtime是jboss 7.
    另外一定别忘了加入 external lib ：jboss-client-7.1.0.Final.jar (JBOSS_HOME/bin/client) 
    否则会报错：
    javax.naming.NamingException: JBAS011843: Failed instantiate InitialContextFactory
     
     User: acs doesn't have permission='SEND' on address jms.queue.testQueue 权限错误，需要看看：
    “jboss-homestabdaloneconfigurationapplication-roles.properties” 
    加一句 testjms=guest
     
    其他错误参见：
    http://www.techartifact.com/blogs/2012/10/jboss-as-7-setting-up-hornetq-jms.html#sthash.OLzvKFO6.dpbs
     
    在测试中遇到收不到消息。可以在控制台查看对应的queue有多少个comsumer。我的代码由于开始没有写consumer.close(). 导致接收完后虽然函数结束没有再调用receve阻塞方法了，但consumer一直存在。从jboss7的管理页面可以看到有好几个consumer。导致再次发送的消息还会被它吃掉。整了一天不断测试才搞明白。
     public Object Receive(String filter, long timeoutReceive) throws JMSException {
        System.out.println ("======enter Receive===" );
        System.out.println("Creating cosumer with filter: " + filter );
        MessageConsumer consumer = queuesession.createConsumer(queue, filter);
        
        Message mrcv = null;
        System.out.println("receive message with timeout="+timeoutReceive);
        mrcv = consumer.receive(timeoutReceive);
        if (mrcv != null) {
            try {
                System.out.println("RCV1: " + mrcv.getJMSCorrelationID());
                System.out.println("====== consumer.close();.=====");
                consumer.close();
                return ((ObjectMessage) mrcv).getObject();;
            } catch (MessageFormatException e) {
                System.out.println("MessageFormatException: " + e.getMessage());
                mrcv.acknowledge();
            }
        } else {
            System.out.println("======receive message time out.=====");
        }
        consumer.close();
        return null;
    }
