RabbitMQ学习之spring配置文件rabbit标签的使用

准备工作

rabbitMq版本：rabbitmq_server-3.6.1

spring版本：spring4.3

POM配置

 <!-- rabbitmq jar-->        <dependency>            <groupId>com.rabbitmq</groupId>            <artifactId>amqp-client</artifactId>            <version>3.6.1</version>        </dependency>        <dependency>            <groupId>org.springframework.amqp</groupId>            <artifactId>spring-rabbit</artifactId>            <version>1.6.1.RELEASE</version>        </dependency>

1.spring配置spring-rabbitmq-consumer.xml

<?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-3.1.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.1.xsd        http://www.springframework.org/schema/rabbit        http://www.springframework.org/schema/rabbit/spring-rabbit-1.3.xsd">    <context:property-placeholder location="classpath:application.properties"/>    <rabbit:connection-factory id="connectionFactory" host="${mq.host}" username="${mq.username}"                               password="${mq.password}" port="${mq.port}"/>    <rabbit:admin connection-factory="connectionFactory"/>    <bean id="rabbitAdmin"          class="org.springframework.amqp.rabbit.core.RabbitAdmin">        <constructor-arg ref="connectionFactory"/>    </bean>    <!--定义rabbit template用于数据的接收和发送-->    <rabbit:template id="amqpTemplate" connection-factory="connectionFactory"  exchange="change_name" routing-key="routing_name"   />    <!-- 监听方式接收 -->    <bean id="messageReceiver" class="com.willow.rabbitmq.QueueListenter"></bean>    <rabbit:listener-container connection-factory="connectionFactory">        <rabbit:listener queues="queue_name" ref="messageReceiver"/>    </rabbit:listener-container>    <!--定义queue-->    <rabbit:queue id="queue_name" name="queue_name" durable="true" auto-delete="false" exclusive="false"/>    <!-- 定义direct exchange，绑定  queue -->    <rabbit:direct-exchange name="change_name" durable="true" auto-delete="false">        <rabbit:bindings>            <rabbit:binding queue="queue_name" key="routing_name"></rabbit:binding>        </rabbit:bindings>    </rabbit:direct-exchange></beans>

2.RabbitMq发送消息接收消息

package com.willow.rabbitmq;import net.sf.json.JSONSerializer;import org.junit.Test;import org.junit.runner.RunWith;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.amqp.core.*;import org.springframework.amqp.rabbit.core.RabbitAdmin;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import java.util.HashMap;import java.util.Map;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {"classpath:spring/spring-rabbitmq-consumer.xml"})public class RabbitMQ {    private static final Logger LOGGER = LoggerFactory.getLogger(RabbitMQ.class);    @Autowired    private AmqpTemplate amqpTemplate;    @Autowired    private RabbitAdmin rabbitAdmin;    public void sendMessage(String queueName, String message) throws Exception {        declareBinding(queueName, queueName);        rabbitAdmin.getRabbitTemplate().convertAndSend(queueName, queueName, message);    }    @Test    public void sendTest() throws Exception {        for (int i = 0; i < 100; i++) {            sendMessage("queue_name", "abc" + i);        }    }    public void receiveMessage(){        Message message = rabbitAdmin.getRabbitTemplate().receive("queue_name");        if (message != null) {            String mes = new String(message.getBody());            LOGGER.info("##########message:{}", mes);        }    }    /**     * 方式一：动态声明exchange和queue它们的绑定关系  rabbitAdmin     * @param exchangeName     * @param queueName     */    protected void declareBinding(String exchangeName, String queueName) {        if (rabbitAdmin.getQueueProperties(queueName) == null) {            Queue queue = new Queue(queueName, true, false, false, null);            rabbitAdmin.declareQueue(queue);            TopicExchange directExchange = new TopicExchange(exchangeName);            rabbitAdmin.declareExchange(directExchange);//声明exchange            Binding binding = BindingBuilder.bind(queue).to(directExchange).with(queueName);    //将queue绑定到exchange            rabbitAdmin.declareBinding(binding);      //声明绑定关系        } else {            rabbitAdmin.getRabbitTemplate().setQueue(queueName);            rabbitAdmin.getRabbitTemplate().setExchange(queueName);            rabbitAdmin.getRabbitTemplate().setRoutingKey(queueName);        }    }    /**     * 方式二  xml配置queue绑定方式，amqpTemplate     * @throws Exception     */    @Test    public void send() throws Exception {        Map<String, Object> bodyMap = new HashMap<String, Object>();        bodyMap.put("message", "rabbitMq_test");        String jsonStr = JSONSerializer.toJSON(bodyMap).toString();        amqpTemplate.convertAndSend(jsonStr);    }}

3.消息监听

package com.willow.rabbitmq;import org.springframework.amqp.core.Message;import org.springframework.amqp.core.MessageListener;/** * Queue监听器 */public class QueueListenter implements MessageListener {    public void onMessage(Message msg) {        try{                  String str=new String(msg.getBody(),"UTF-8");            System.out.println("监听器：message"+str);        }catch(Exception e){            e.printStackTrace();        }    }   }
