Rabbitmq topic provider project
(1) Order message sender

Rabbitmq topic consumer project
(1) Info recipient
package com.ebook.rabbitmq; import org.springframework.amqp.core.ExchangeTypes; import org.springframework.amqp.rabbit.annotation.*; import org.springframework.stereotype.Component; /** * @author:JZ * @date:2020/2/2 */ @Component @RabbitListener(bindings = @QueueBinding( value = @Queue(value = "${mq.config.queue.info}", autoDelete = "true"),//autoDelete indicates that the queue is temporary exchange = @Exchange(value = "${mq.config.exchange}", type = ExchangeTypes.TOPIC), key = "*.log.info" )) public class InfoReciver { @RabbitHandler public void process(String msg) { System.out.println("Receive INFO Journal:" + msg); } }
(2) Error message receiver
package com.ebook.rabbitmq; import org.springframework.amqp.core.ExchangeTypes; import org.springframework.amqp.rabbit.annotation.*; import org.springframework.stereotype.Component; /** * @author:JZ * @date:2020/2/2 */ @Component @RabbitListener(bindings = @QueueBinding( value = @Queue(value = "${mq.config.queue.error}", autoDelete = "true"),//autoDelete indicates that the queue is temporary exchange = @Exchange(value = "${mq.config.exchange}", type = ExchangeTypes.TOPIC), key = "*.log.error" )) public class ErrorReciver { @RabbitHandler public void process(String msg) { System.out.println("Receive ERROR Journal:" + msg); } }
(3) All message recipients
package com.ebook.rabbitmq; import org.springframework.amqp.core.ExchangeTypes; import org.springframework.amqp.rabbit.annotation.*; import org.springframework.stereotype.Component; /** * @author:JZ * @date:2020/2/2 */ @Component @RabbitListener(bindings = @QueueBinding( value = @Queue(value = "${mq.config.queue.logs}", autoDelete = "true"),//autoDelete indicates that the queue is temporary exchange = @Exchange(value = "${mq.config.exchange}", type = ExchangeTypes.TOPIC), key = "*.log.*" )) public class LogsReciver { @RabbitHandler public void process(String msg) { System.out.println("Receive ALL Journal:" + msg); } }
