You 've probably heard of Java Message Service (JMS ). it's a standard Java API for creating, sending, processing ing and reading messages. activeMQ, an Apache project, is an open source message broker that supports JMS 1.1. in addition to supporting JMS, it supports other protocols that allow clients to be written in a variety of ages. look at this page for more information. sounds good, doesn' t it? Let's

ACTIVEMQ is a powerful messaging server that supports a variety of development languages such as Java, C, C + +, C #, and more. Enterprise-level messaging servers, regardless of server stability or speed, requirements are very high, and ACTIVEMQ distributed cluster can be very good to meet this demand, the following is a few ACTIVEMQ cluster configuration.Queue C

Solution: Introduce a broker component to decouple the client and server side. The server registers itself to broker, allowing the client to access the service by exposing the interface. The client sends the request through

convenient, the data readability is strong. Of course its limitations are also obvious: on the security/message ACK mechanism/transaction support/and the asynchronous operation of the message (relative to Openwire). Both consumers and producers need to describe the operation through URLs, which limits the client-side tuning under the rest protocol and is limited by the HTTP protocol (: keep-alive) and the servlet container's ability to support asynchrony.

ActiveMQ is a Java-based open-source Message Server product. Therefore, we can integrate it into a business system implemented through Java. The following is a brief summary of the integration method.

Recently, you want to learn about JMS and then learn about ACTIVEMQ, which is recorded here.1.ActiveMQ Introduction ACTIVEMQ Official website: http://activemq.apache.org/ (The following excerpt from Baidu Encyclopedia) ActiveMQ is the most popular, powerful, open source messaging bus that Apache has produced.

. If it exists, then broker checks to see if any consumer owns the message group. If not, then broker selects a consumer and associates it with this message group. Thereafter, this consumer will receive all messages from this message group until: consumer is closed. Message group is closed. By sending a message and setting the JMSXGROUPSEQ for this message to 0. Starting with version 4.1,
