2.创建配置文件

　　a.创建 spring.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:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 自动扫描的包名 -->
    <context:component-scan base-package="com.wode" />

    <!-- 开启AOP代理 -->
    <aop:aspectj-autoproxy proxy-target-class="true" />

    <!--开启注解处理器 -->
    <context:annotation-config>
    </context:annotation-config>

    <context:property-placeholder location="classpath:rabbit.properties"/>
    <!-- Spring中引入其他配置文件 -->
    <import resource="classpath*:/spring-rabbit.xml" />

</beans>

　　b.创建 spring-rabbit.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

        <rabbit:listener queues="topic.queue.2" ref="topicConsumerManual" />
    </rabbit:listener-container>


</beans>

　　c.创建 rabbit.properties

#RabbitMQ服务器地址，默认值"localhost"
rabbit.ip=localhost
#RabbitMQ服务端口，默认值为5672
rabbit.port=5672
#访问RabbitMQ服务器的账户,默认是guest
rabbit.username=guest
#访问RabbitMQ服务器的密码,默认是guest
rabbit.password=guest

#路由标识
routing.1=1
routing.2=2

3.创建生产者

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

@Component
public class CommonProducer {

    //direct模式
    @Resource(name = "rabbitTemplate")
    private AmqpTemplate rabbitTemplate;

    @Value("${routing.1}")
    private String routing1;
    @Value("${routing.2}")
    private String routing2;

    //fanout模式
    @Resource(name = "fanoutRabbitTemplate")
    private AmqpTemplate fanoutRabbitTemplate;

    //topic模式
    @Resource(name = "topicRabbitTemplate")
    private AmqpTemplate topicRabbitTemplate;


    public void send(){
        rabbitTemplate.convertAndSend(routing1, "routing1");
        rabbitTemplate.convertAndSend(routing2, "routing2");

        fanoutRabbitTemplate.convertAndSend("fanoutMsg");

        topicRabbitTemplate.convertAndSend("order.insert", "order.insert");
        topicRabbitTemplate.convertAndSend("order.update", "order.update");
    }

}

4.创建direct模式消费者

　　a.自动提交消费者，对应配置文件中 acknowledge="auto"

import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;

public class DirectConsumerAuto implements ChannelAwareMessageListener {
    @Override
    public void onMessage(Message message, Channel channel) throws Exception {
        String msg = new String(message.getBody(),"UTF-8");
        System.out.println("[DirectConsumerAuto]消费者接收到：" + msg);
    }
}

　　b.手动提交消费者，对应配置文件中 acknowledge="manual"

import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;

public class DirectConsumerManual implements ChannelAwareMessageListener {
    @Override
    public void onMessage(Message message, Channel channel) throws Exception {
        String msg = new String(message.getBody(),"UTF-8");
        System.out.println("[DirectConsumerManual]消费者接收到：" + msg);
        //手动确认
        channel.basicAck(message.getMessageProperties().getDeliveryTag(), true);
    }
}

5.创建fanout模式消费者

　　a.自动提交消费者，对应配置文件中 acknowledge="auto"

import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;

public class FanoutConsumerAuto implements ChannelAwareMessageListener {
    @Override
    public void onMessage(Message message, Channel channel) throws Exception {
        String msg = new String(message.getBody(),"UTF-8");
        System.out.println("[FanoutConsumerAuto]消费者接收到：" + msg);
    }
}

　　b.手动提交消费者，对应配置文件中 acknowledge="manual"

import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;

public class FanoutConsumerManual implements ChannelAwareMessageListener {
    @Override
    public void onMessage(Message message, Channel channel) throws Exception {
        String msg = new String(message.getBody(),"UTF-8");
        System.out.println("[FanoutConsumerManual]消费者接收到：" + msg);
        //手动确认
        channel.basicAck(message.getMessageProperties().getDeliveryTag(), true);
    }
}

6.创建topic模式消费者

　　a.自动提交消费者，对应配置文件中 acknowledge="auto"

import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;

public class TopicConsumerAuto implements ChannelAwareMessageListener {
    @Override
    public void onMessage(Message message, Channel channel) throws Exception {
        String msg = new String(message.getBody(),"UTF-8");
        System.out.println("[TopicConsumerAuto]消费者接收到：" + msg);
    }
}

　　b.手动提交消费者，对应配置文件中 acknowledge="manual"

import com.rabbitmq.client.Channel;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;

public class TopicConsumerManual implements ChannelAwareMessageListener {
    @Override
    public void onMessage(Message message, Channel channel) throws Exception {
        String msg = new String(message.getBody(),"UTF-8");
        System.out.println("[TopicConsumerManual]消费者接收到：" + msg);
        //手动确认
        channel.basicAck(message.getMessageProperties().getDeliveryTag(), true);
    }
}

7.测试

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring.xml");
        CommonProducer commonProducer = (CommonProducer) applicationContext.getBean("commonProducer");
        commonProducer.send();
    }
