RabbitMQ

1.RabbitMQ的jar包

<dependency>
    <groupId>com.rabbitmq</groupId>
    <artifactId>amqp-client</artifactId>
    <version>3.6.5</version>
</dependency>

<dependency>
    <groupId>org.springframework.amqp</groupId>
    <artifactId>spring-rabbit</artifactId>
    <version>1.4.6.RELEASE</version>
</dependency>

2.配置RabbitMQ与Spring整合xml

<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 
           http://www.springframework.org/schema/context/spring-context.xsd  
           http://www.springframework.org/schema/rabbit 
           http://www.springframework.org/schema/rabbit/spring-rabbit.xsd">

    <!--配置connection-factory，指定连接rabbit server参数 -->
    <rabbit:connection-factory id="connectionFactory"
        host="${rabbit.connect.host}" //路径
        port="${rabbit.connect.port}" //端口号
        username="${rabbit.connect.username}"//用户名
        password="${rabbit.connect.password}" //密码
        channel-cache-size="${rabbit.connect.channelCacheSize}"//连接大小
        publisher-returns="true" publisher-confirms="true" />

    <!--通过指定下面的admin信息，当前producer中的exchange和queue会在rabbitmq服务器上自动生成 -->
    <rabbit:admin connection-factory="connectionFactory" />
    <rabbit:template id="hzyMQ" connection-factory="connectionFactory"/>//相当于做一个模板，谁发送消息到服务端就要注入这个bean进去

    <!--定义对列 说明：durable:是否持久化 exclusive: 仅创建者可以使用的私有队列，断开后自动删除 auto_delete: 当所有消费客户端连接断开后，是否自动删除队列 -->
    <rabbit:queue name="messageAsset" durable="true" auto-delete="false" exclusive="false" />

    <!--定义direct-exchange -->
    <rabbit:direct-exchange name="hzyMQ.Exchange" durable="true" auto-delete="false">
        <rabbit:bindings>
            <rabbit:binding queue="messageAsset" key="HZYtMessage"></rabbit:binding>
        </rabbit:bindings>
    </rabbit:direct-exchange>

    //定义接收者
    <bean id="msgListener" class="cn.hzy.MsgAssetListener"/>

    <!-- queue litener 观察 监听模式 当有消息到达时会通知监听在对应的队列上的监听对象 配置手工确认-->
    <rabbit:listener-container connection-factory="connectionFactory" acknowledge="auto" concurrency="5" prefetch="3" max-concurrency="10">
        <rabbit:listener queues="messageAsset" ref="msgListener" />
    </rabbit:listener-container>

</beans>

3.生产者

@Component("hzyMQService")
@Transactional
public class HzyMQService {

    @Autowired
    @Qualifier("hzyMQ")
    private AmqpTemplate hzyMQ;

    @Override
    public void sendAssetMessage(String content){
        //第一个参数:通道
        //第二个参数:对列名称
        //第三个参数:消息
        hzyMQ.convertAndSend("hzyMQ.Exchange", "HZYtMessage", content);
    }


}

4.消费者

public class MsgAssetListener implements MessageListener {

    public void onMessage(Message message) {
         String json = new String(message.getBody());
         System.out.println("【MsgAssetListener 接收到消息】:"+json);
    }

}
