We currently use Spring Integration for ActiveMQ, I would like to know if its a drastic change to move to RabbitMQ(AMQP) even with Spring Integration. Is there any bridge similar to what ActiveMQ uses to do JMS<->AMQP forwarding ? ActiveMQ also supports AMQP: http:/

问题 Is there a way to run a loopback JMS adapter that will only be detected locally? I'm not sure if my terminology is correct, but I want the ActiveMQ broker to only be connectible from the same machine that the broker is running on. 回答1: Make sure it's connector is only listening on localhost look in the config.xml files and change all 0.0.0.0 adresses to 127.0.0.1 来源： https://stackoverflow.com/questions/3669765/activemq-broker-connectible-only-on-localhost

Architecture of a web application using message queues

问题 I have a java web application which uses some form of custom message queuing via a database table (EmailQueue) to queue delivery of emails. The application is deployed on Tomcat and uses Quartz jobs which polls for new entries in the EmailQueue table to send.
