Consumer配置文件

实现过程都是创建监听类，实现MessageListener，重写其中的onMessage方法

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit.xsd"> <!--加载配置文件--> <context:property-placeholder location="classpath:rabbitmq.properties"/> <!-- 定义rabbitmq connectionFactory --> <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}" port="${rabbitmq.port}" username="${rabbitmq.username}" password="${rabbitmq.password}" virtual-host="${rabbitmq.virtual-host}"/> <bean id="springQueueListener" class="com.sx.rabbitmq.listener.SpringQueueListener"/> <rabbit:listener-container connection-factory="connectionFactory" auto-declare="true"> <rabbit:listener ref="springQueueListener" queue-names="spring_queue"/> </rabbit:listener-container> </beans>

Consumer代码

package com.sx.rabbitmq.listener; import org.springframework.amqp.core.Message; import org.springframework.amqp.core.MessageListener; public class SpringQueueListener implements MessageListener { @Override public void onMessage(Message message) { System.out.println(new String(message.getBody())); } }
