　　c.创建 rabbit.properties

12    private AmqpTemplate rabbitTemplate;
13
14    @Value("${routing.1}")
15    private String routing1;
16    @Value("${routing.2}")
17    private String routing2;
18
19    //fanout模式
20    @Resource(name = "fanoutRabbitTemplate")
21    private AmqpTemplate fanoutRabbitTemplate;
22
23    //topic模式
24    @Resource(name = "topicRabbitTemplate")
25    private AmqpTemplate topicRabbitTemplate;
26
27
28    public void send(){
29        rabbitTemplate.convertAndSend(routing1, "routing1");
30        rabbitTemplate.convertAndSend(routing2, "routing2");
31
32        fanoutRabbitTemplate.convertAndSend("fanoutMsg");
33
34        topicRabbitTemplate.convertAndSend("order.insert", "order.insert");

8        String msg = new String(message.getBody(),"UTF-8");
9        System.out.println("[DirectConsumerManual]消费者接收到：" + msg);
10        //手动确认
11        channel.basicAck(message.getMessageProperties().getDeliveryTag(), true);
12    }
13}

3import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;
4
5public class FanoutConsumerAuto implements ChannelAwareMessageListener {
6    @Override
7    public void onMessage(Message message, Channel channel) throws Exception {
8        String msg = new String(message.getBody(),"UTF-8");
9        System.out.println("[FanoutConsumerAuto]消费者接收到：" + msg);
10    }
11}

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

8        String msg = new String(message.getBody(),"UTF-8");
9        System.out.println("[FanoutConsumerManual]消费者接收到：" + msg);
10        //手动确认
11        channel.basicAck(message.getMessageProperties().getDeliveryTag(), true);
12    }
13}

4
5public class TopicConsumerAuto implements ChannelAwareMessageListener {
6    @Override
7    public void onMessage(Message message, Channel channel) throws Exception {
8        String msg = new String(message.getBody(),"UTF-8");
9        System.out.println("[TopicConsumerAuto]消费者接收到：" + msg);
10    }
11}

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

1import com.rabbitmq.client.Channel;
2import org.springframework.amqp.core.Message;
3import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;

5public class TopicConsumerManual implements ChannelAwareMessageListener {
6    @Override
7    public void onMessage(Message message, Channel channel) throws Exception {
8        String msg = new String(message.getBody(),"UTF-8");
9        System.out.println("[TopicConsumerManual]消费者接收到：" + msg);
10        //手动确认
11        channel.basicAck(message.getMessageProperties().getDeliveryTag(), true);
12    }
13}

7.测试

1public static void main(String[] args) {
2        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring.xml");
3        CommonProducer commonProducer = (CommonProducer) applicationContext.getBean("commonProducer");
4        commonProducer.send();
5    }
