subscriber registers the event that he wants to subscribe to the dispatch center, when the event triggers, the Publisher publishes the event to the Dispatch center (incidentally), and the dispatch center uniformly dispatches the subscriber to the dispatch center's processing code.For example, an interface is a real-time display of weather, it subscribes to weather events (registered to the dispatch center, including handlers), when the weather changes (timing to obtain data), as the publisher t
New users focus on the public platform and will generate a subscription event, the subscribe event , which does not respond appropriately to this event in the default code.After the new user has focused on the public platform, it may be interesting to know what features the platform provides and how to use it, which is a "user's manual" for the platform.This article will detail the processing of the Subscribe event, and respond to the corresponding in
First, publish the subscription messageA publish Subscription (PUB/SUB) is a message communication pattern that is primarily designed to decouple the coupling between a message publisher and a subscriber, and Redis acts as a pub/sub server, with the ability to route messages between subscribers and publishers. Subscribers can subscribe to Redis server for the type of message they are interested in by using

What is message-oriented middleware? The publishing and subscription of point-to-point message-oriented middleware is asynchronous communication.

Redis pub/sub is a message communication mode: the sender (pub) sends messages, and the subscriber (sub) receives messages.
Redis clients can subscribe to any number of channels.

JMS is a Java Message Service. JMS clients can transmit messages asynchronously through the JMS service. JMS supports two message models: point-to-point (P2P) and publish/subscribe (pub/Sub), that is, point-to-point and publish subscription models.P2P
The P2P model has the following concepts: queue, sender, and receiver ). Each message is sent to a specific queue, and the receiver obtains the message from the queue. The queue retains messages until

The first part is quoted in: Click to open1: Brief IntroductionPub-sub mode is not generally processed by the system's key data. The Publisher does not care if the Subscriber receives the published message, nor does the subscriber know if he or she has received all the messages from the publisher. You also don't know when subscribers start receiving messages. Similar to broadcasting, radio. So logically, it's not reliable. This can be solved by combining with the request response model.Figure 1:
