由于一些原因，最近要復(fù)習(xí)一些東西，所以就把JMS的東西再?gòu)?fù)習(xí)一遍，以下便是例子

jms 中最重要的幾個(gè)概念destination，ACKNOWLEDGE，subscribe,durable subscribe

destination：topic queque
  queue簡(jiǎn)單點(diǎn)說(shuō)就是1:1 一個(gè)消息只能由一個(gè)consumer去消費(fèi)，別的consumer來(lái)消費(fèi)的時(shí)候已經(jīng)沒(méi)了，先到先得
topic簡(jiǎn)單點(diǎn)說(shuō)就是1:N 一個(gè)消息可以由多個(gè)consumer來(lái)消費(fèi)，誰(shuí)來(lái)消費(fèi)都有
 subscribe，拿topic來(lái)說(shuō)如果當(dāng)前訂閱不是持久訂閱，只有再訂閱后生產(chǎn)者生產(chǎn)得消息才能被consumer得到，持久訂閱只要沒(méi)有被consumer消費(fèi)，早晚會(huì)消費(fèi)這個(gè)消息
 
 
 
 一下是幾個(gè)例子
 
 queuesend：queque消息產(chǎn)生
 queuereceive：queque消息得消費(fèi)
 topicsend ：topic消息得產(chǎn)生
 topicreceive1：topic消息的非訂閱
 topicrecieve2：topic消息的持久訂閱
 
 這個(gè)例子實(shí)在WEBLOGIC814上測(cè)試過(guò)的，當(dāng)然要定義JMSSERVER,FACTORY,DESTINATION。
