A message object has three parts: the message header, the message attribute, and the message data itself. It is called a payload or message body. 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 ).

The full name of JMS is the Java message service, or Java messaging services. It is used primarily for messaging between producers and consumers, where producers are responsible for generating messages, and consumers are responsible for receiving messages. To apply it to the actual business requirements we can use the producer to generate a message and send it at a specific time, and the corresponding consumer will complete the corresponding business
The Java Message Service (jms) application interface is an API for Message-oriented middleware (MOM) on the Java platform. It is used between two applications, or send messages in a distributed system for asynchronous communication. Java Message Service is an API unrelated to a specific platform. Most MOM providers provide support for JMS. Jms can also be referre
RMI uses synchronous communication, and JMS uses asynchronous communication.There are two main concepts in JMS: The message broker and the destination (destination). The disadvantage of synchronous communication, which can be solved by using JMS: Run Apache-activemq-5.10.0-bin[1]\apache-activemq-5.10.0\bin\win32 under Activemq.bat to start the

The Topic mechanism of message middleware does not normally save messages. Without a connection, you will not receive a message when you connect again without losing your connection. This mechanism is well applied to scenarios where messages can be lost. Of course, message middleware has the ability to save messages. Durablesubscriber is defined in the
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 ...).
