This article is a simple integration method for spring and activemq. It is only used for reference learning and focuses on understanding concepts.
1: JMS is a set of standard APIs developed by Sun to access message-oriented middleware (MOM). The mom component used in this article is activemq. You can go to [url] routing,
It is very simple to use, extract and directly run the activemq. BAT file under the D:/activemq-4.1.1/bin directory, you can start the service. In addition, we only perform simple tests, so we do not need to configure the content related to JNDI. Service Startup
Then we can see that the corresponding port is started, so that my mom component is ready... 2: Next, we will create a new web project (myeclipse is used) and import related packages. We recommend that you do not use the spring2.0 package that comes with myeclipse, this is because the debugging has been performed on several projects for a long time, because the package has a problem. Haha.
Import spring2.0.jar, apache-activemq-4.1.1.jar, commons-pool-1.2.jar, long4j. jar, commons-logging-1.1.jar file to the lib directory. Next, create two XML files under the WEB-INF <?
