ActiveMQ is the most popular, powerful, open source messaging bus that Apache has produced. ActiveMQ is a JMS provider implementation that fully supports the JMS1.1 and the Java EE 1.4 specification, although the JMS specification has been around for a long time, but JMS still plays a special role in the middle of today's Java EE applications.ACTIVEMQ Feature List1.

Before writing an article about active and Message Queuing push-pull mode, you can refer to: LinkFor more information on Active vs. RABBITMQ and other comparisons, there are the following records:This article link refers to:Basic introductionRabbitMQ: based on the AMQP protocol ( Advanced Message Queue Protocol)ActiveMQ: based on Stomp Protocol (Note: I only know that it is based on JMS)The RabbitMQ is an MQ implemented by AMQP with Erlang. The reason

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.

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:

1 Overview
For the scale-out and high availability of the system required for massive messages, ACTIVEMQ provides a clustering feature for network connectivity patterns.
Simply put, it is by connecting a number of different broker instances together as a whole to provide services to the outside, thereby improving the overall external messaging capabilities.
Between broker instances that are connected in this way, the queue and consumer list can be sha
Note: (Delete inactive queues (delete Inactive destinations))
In general, ACTIVEMQ's topic and queue can be removed from the Web console or JMX after they are not used.Of course, it can also be configured so that the broker can automatically detect useless queues (a queue that is empty for a certain period of time) and remove them and reclaim the response resources.Implementing scheduled automatic cleanup of invalid topic and queue requires setting th
