Recently want to learn MOM (message middleware: Messages oriented middleware), from the comparative basis of ACTIVEMQ learning, RabbitMQ, ZeroMQ, ROCKETMQ, Kafka and other follow-up to learn.It says that ACTIVEMQ is a kind of message middleware, but why use ACTIVEMQ?In the absence of JMS, many applications will have synchronous communication (after the client ini

RABBITMQ is a high-performance message queue that supports, or is implemented, the AMQP protocol (Advanced Message Queue Protocol Premium Messaging Queuing protocol).Here's a quick example. We first need to deploy a good rabbitmq, and then implement a producer-consumer, the producer to Rabbit to publish a message, the consumer to rabbit to take this message, after the correct receipt of this message, the consumer will return to the queue to write back

The Fanout configuration based on the spring AMQP RABBITMQ is as follows:Publishing side /*** @Title: Mqproducerimpl.java* @Package COM.CYL.RABBITMQ* @Description: TODO (describe what the file does in a sentence)* @author [email protected]* @date April 25, 2016 1:12:46* @version V1.0*/Package COM.CYL.RABBITMQ;Import Org.springframework.amqp.core.AmqpTemplate;Import org.springframework.beans.factory.annotation.Autowired;Import Org.springframework.ster

1, the difference between the communication platformJMS: Only allow communication between the Java-based implementation of the messaging platformAMQP: Allows multiple message protocols to communicate, such as Ruby's Storm and Java JMS can communicate on AMQP.Conclusion: AMQP allows multiple techniques for simultaneous protocol communication 2, the difference of communication mechanismJMS: Message producers and message consumers must know each other's

1. The camel framework supports a large number of enterprise integration models, which can greatly simplify the large number of services and complex message flows between integrated components. The spring framework focuses more on simplicity and supports only basic best practices.2. The core architecture of the spring message is jmstemplate, which isolates the tedious operations like opening, closing sessions and producer, so application developers simply need to focus on the actual business log
