Message format:Establishes a message queue between two clients through peer-to-peer transmission through queues.Note: similar to the queue in the data structure, the first-in-first-outTopic message.

In order to understand this article, we want the reader to have a fairly solid foundation for Java programming before we begin. We will try to explain what JMS is as simple as possible, but before you can build your own programs and understand them correctly, you need to have some experience using Jndi to develop the actual application. JMS (Java Messaging Service) is a message exchange standard that allow

ActiveMQ is a high-performance messaging middleware, primarily for JMS implementations, while other languages can be used as well. Its support point to point, publish/subscribe, push-pull mode, specific reader network, here slightly. 1, the first download ACTIVEMQ, and successfully started the service. 2, build Maven project, add dependencies Activemq-all-5.6.0.jar 3, Jms.xml 4.

There is a time dependency between the Publisher and the Subscriber . Subscribers to a topic (TOPIC) must create a subscription before they can consume the publisher's message and, in order to consume the message, the Subscriber must remain in a running state.Of course, to mitigate this strict time dependency, JMS
