ACTIVEMQ Message QueuingActiveMQ is the most popular, powerful, open source messaging bus that Apache has produced. ActiveMQ is a JMS Provider that fully supports JMS1.
Spring boot also provides automatic configuration support for the JMS (Java message Service,java message Service), which mainly supports JMS implementations such as ACTIVEMQ, Artemis, and so on. Here take ACTIVEMQ as an example.First, the use of embedded ActiveMQ1. Add Activemq Start dependencyAdd

Usage Scenarios:
In the project, some operations without immediate return and time-consuming are extracted and processed asynchronously, which greatly saves the request response time of the server and improves the throughput of the system.

JMS (Professional technical specifications on the Java platform)
The JMS-the Java Message Service-application interface is a Java platform-oriented messaging middleware (MOM) API for sending messages and communicating asynchronously between two applications, or distributed systems. The Java Messaging Service is a platform-independent API, with most MOM providers supporting JMS.
JMS consists of the following elements:
JMS provider: Implementation of JMS, class such as:

Amqp (Advanced Message Queue Protocol) Is the specification for the interaction between a message client and a broker. It is a specification for wire-level protocol communication between client and Message Broker. Unlike activemq, activemq is a message system, but a message protocol.

First, why use ACTIVEMQ
The JMS (Java Message Service) channel may be used in the design of the bus, and the Java Messaging Services (JMS) goes beyond the manufacturer's proprietary mom (Message-oriented-middleware) API. It provides a set of APIs for enterprise messaging. The goal of JMS is to provide a standard API that uses the Java language to send and receive messages in a producer-neutral manner. The JMS API minimizes the amount of enterprise mes
