Queue implements the point-to-point model. In the following example, two consumers are started to listen to a queue and then send multiple messages to the queue cyclically.

Messages can carry important data or are only used for System Event Notifications. In most cases, messages are used as notifications and data-carrying tools at the same time. Let's talk about the message header first. Each JMS message has a set of standard message headers. Each message header is identified

First of all, when doing any technical pre-Research: what will I do to clear it? Why use it? What is JMS? Java Message Service is a set of interfaces and related semantics. It defines how JMS customers can access the functions of Enterprise message generation. JMS supports two transmission modes of message-oriented middleware: point-to-point and pub/Sub ).

Writing a simple JMS example, the use of Jndi is for versatility, and the example uses the generic interface provided by the JMS specification, without using the interface of the specific JMS provider, which guarantees that the program we write is suitable for any JMS implementation (ActiveMQ, HornetQ ...). What is Jnd

The first post is a basic concept of JMS (a) –JMS, we introduce two kinds of JMS message models: The point-to-point and the publish-subscribe model, and the two ways messages are consumed: synchronous and asynchronous, the JMS programming model object, and finally the advantages of JMS.Second blog Brief introduction to

In the real enterprise, the application of message communication has been very hot, and plays a special role in the enterprise application of the Java EE, so it is very necessary to study it.In brief, the basic concept of JMS (a) –JMS, we introduce the canonical JMS of message communication, we introduce an open source JMS
