2 MQ Overview
MQ full nameMmessageQueue (message queue) is a container for storing messages during message transmission. It is mostly used for communication between distributed systems.
Reach the following effect
- MQ, message queue, middleware for storing messages
- There are two ways of distributed system communication: direct remote call and indirect communication with the help of a third party
- The sender is called the producer and the receiver is called the consumer
3&4 MQ Advantages and Disadvantages
Advantages :
- application decoupling
- Asynchronous speed up
Disadvantages of peak shaving and valley filling :
5 Common MQ products
At present, there are many MQ products in the industry, such as RabbitMQ, RocketMQ, ActiveMQ, Kafka, ZeroMQ, MetaMq, etc., and there are also cases of directly using Redis as a message queue. Consider your own needs and MQ product features comprehensively.
6 Introduction to RabbitMQ
AMQP,Right nowAdvanced Message Queuing Protocol(Advanced Message Queuing Protocol), is a network protocol,
an open standard of application layer protocol, designed for message-oriented middleware. The client and message middleware based on this protocol can transfer messages, and are not
limited by different client/middleware products, different development languages and other conditions. In 2006, the AMQP specification was released.Analogous to HTTP.
In 2007, RabbitMQ 1.0 developed by Rabbit Technology Company based on the AMQP standard was released. RabbitMQ is developed in Erlang language.
The Erlang language was designed by Ericson, a language specially developed for the development of highly concurrent and distributed systems, and is widely used in the telecommunications field.
The RabbitMQ infrastructure is as follows:
RabbitMQ provides 6 working modes: Simple mode, work queues, Publish/Subscribe publishing and subscription mode, Routing
routing mode, Topics topic mode, RPC remote call mode (remote call, not too MQ; no introduction for now).
Introduction to the corresponding mode on the official website: https://www.rabbitmq.com/getstarted.html
JMS
- MS is the Java Message Service (JavaMessage Service) application programming interface, which is an API for message-oriented middleware in the Java platform
- JMS is one of the JavaEE specifications, analogous to JDBC
- Many message middleware implement the JMS specification, for example: ActiveMQ. RabbitMQ does not officially provide JMS implementation packages, but the open source community has
summary
1. RabbitMQ is a message queue product developed in Erlang language based on AMQP protocol.
2. RabbitMQ provides 6 working modes, and we learn 5 of them. This is the focus of today.
3. AMQP is a protocol, analogous to HTTP.
4. JMS is an API specification interface, analogous to JDBC.
RabbitMQ installation and configuration
- RabbitMQ official address: http://www.rabbitmq.com/
- Installation document: Documentation/Software/Installation RabbitMQ.md
Getting Started
Requirement: Use simple mode to complete message delivery
Steps:
①Create project (generator, consumer)
②Add dependencies respectively
③Write producer to send message
④Write consumer to receive message
