SpringMVC集成RabbitMQ

        RabbitMQ在集成到SpringMVC的过程中，可能会遇到很多坑，网上很多配置都有问题，要么无法发消息，要么无法接收消息，LZ特将能够使用的配置发出来，分享给大家。

        首先添加Maven依赖：

<dependency>          <groupId>org.springframework.amqp</groupId>          <artifactId>spring-rabbit</artifactId>           <version>1.3.6.RELEASE</version>      </dependency>    <dependency>      <groupId>com.rabbitmq</groupId>      <artifactId>amqp-client</artifactId>      <version>3.5.1</version>    </dependency>

创建配置文件，application-mq.xml

添加代码：

<beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:rabbit="http://www.springframework.org/schema/rabbit"     xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd     http://www.springframework.org/schema/rabbit    http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd" >    <description>rabbitmq 连接服务配置</description>    <!-- 连接配置 -->        <bean id="connectionFactory" class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">    <property name="username" value="lynn"></property>    <property name="password" value="lynn"></property>    <property name="virtualHost" value="/"></property>    <property name="addresses" value="192.168.1.38:5672"></property>    <property name="publisherConfirms" value="true"></property>    </bean>    <!-- spring template声明-->    <bean id="rabbitTemplate"  class="org.springframework.amqp.rabbit.core.RabbitTemplate">        <constructor-arg name="connectionFactory" ref="connectionFactory"/>      <!--消息确认回调 -->      <property name="confirmCallback" ref="producer"/></bean>      <bean id="queue" class="org.springframework.amqp.core.Queue">    <constructor-arg name="name" value="spring-boot-queue"></constructor-arg>    <constructor-arg name="durable" value="true"></constructor-arg>    </bean>        <bean id="exchange" class="org.springframework.amqp.core.DirectExchange">    <constructor-arg name="name" value="spring-boot-exchange"></constructor-arg>    </bean>     <bean id="binding" class="cn.sunsharp.bigdata.mq.MyBinding" init-method="createBinding">     <constructor-arg index="0" ref="queue"></constructor-arg>          <constructor-arg index="1" ref="exchange"></constructor-arg>          <constructor-arg index="2" value="spring-boot-routingKey"></constructor-arg>      </bean>           <bean name="queueListenter" class="cn.sunsharp.bigdata.mq.QueueListenter"></bean>      <bean name="producer" class="cn.sunsharp.bigdata.mq.RmqProducer"></bean>            <bean id="messageContainer" class="org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer">      <property name="queues" ref="queue"></property>      <property name="exposeListenerChannel" value="true"></property>      <property name="maxConcurrentConsumers" value="10"></property>      <property name="concurrentConsumers" value="2"></property>      <property name="connectionFactory" ref="connectionFactory"></property>      <property name="acknowledgeMode" value="MANUAL"></property>      <property name="messageListener" ref="queueListenter"></property>      </bean>            </beans>

添加Java代码：

生产者：

package cn.sunsharp.bigdata.mq;import java.util.UUID;import org.springframework.amqp.rabbit.connection.ConnectionFactory;import org.springframework.amqp.rabbit.core.RabbitTemplate;import org.springframework.amqp.rabbit.core.RabbitTemplate.ConfirmCallback;import org.springframework.amqp.rabbit.support.CorrelationData;import org.springframework.beans.factory.annotation.Autowired;public class RmqProducer implements ConfirmCallback{private RabbitTemplate template;@Autowiredpublic RmqProducer(RabbitTemplate template){this.template = template;}    /* (non-Javadoc)     * @see com.stnts.tita.rm.api.mq.MQProducer#sendDataToQueue(java.lang.String, java.lang.Object)     */    public void sendMessage(String content) {        try {        CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());        template.convertAndSend("spring-boot-exchange", "spring-boot-routingKey",content,correlationId);        } catch (Exception e) {        e.printStackTrace();        }    }@Overridepublic void confirm(CorrelationData correlationData, boolean ack) {System.out.println(" 回调id:" + correlationData+"ack:"+ack);  }}

消费者：

package cn.sunsharp.bigdata.mq;import org.springframework.amqp.core.Message;import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;import com.rabbitmq.client.Channel;public class QueueListenter implements ChannelAwareMessageListener{@Override      public void onMessage(Message message, Channel channel) throws Exception {          byte[] body = message.getBody();        System.out.println("receive msg : " + new String(body));          channel.basicAck(message.getMessageProperties().getDeliveryTag(), false); //确认消息成功消费      }}

//必须要添加如下这个类，否者无法接收消息。

package cn.sunsharp.bigdata.mq;import org.springframework.amqp.core.Binding;import org.springframework.amqp.core.BindingBuilder;import org.springframework.amqp.core.DirectExchange;import org.springframework.amqp.core.Queue;public class MyBinding {private Queue queue;private DirectExchange exchange;private String routingkey;private MyBinding(Queue queue,DirectExchange exchange,String routingkey){this.queue = queue;this.exchange = exchange;this.routingkey = routingkey;}public Binding createBinding(){return BindingBuilder.bind(queue).to(exchange).with(routingkey);}}

下面测试代码：

@Resource(name="producer")    private RmqProducer producer;  public voidtest(){try {//发送消息  producer.sendMessage("test");  } catch (Exception e) {e.printStackTrace();}}

控制台即可打印接收到的消息。
