JMS做爲一個支持點對點(PTP)和訂閱式(pub/sub)式的消息中間件,爲不少項目開發者所使用。Spring對JMS提供了很好的支持,能夠經過JmsTemplate來方便地實現消息服務,因爲JMS對Spring的支持性很好,本文將着重於詳細說明如何spring如何整合jms作簡單的測試用例:java
spring.jar , activemq-all-5.4.3.jar , commons-logging-api-1.1.jar , commons-io-1.3.2.jar,這些jar包能夠去本文最後面的連接裏下載。web

好了,本文主要就是測試基本的spring整合jms。另:下面是我在淘寶上看到的JMS教學視頻,若是朋友們想要細緻的學習JMS,能夠移步到這裏下載JMS視頻:JMS教學視頻-淘寶spring
下篇文章將着重講解如何開發訂閱模式jms,並將闡述如何將ActiveMQ嵌入Spring中。apache
