1.4 编写代码发送消息

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring-rabbitmq-producer.xml")
public class ProducerTest {

    //1.注入 RabbitTemplate
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void testHelloWorld(){
        //2.发送消息
        rabbitTemplate.convertAndSend("spring_queue","hello world spring....");
    }

    /**
     * 发送fanout消息
     */
    @Test
    public void testFanout(){
        //2.发送消息
        rabbitTemplate.convertAndSend("spring_fanout_exchange","","spring fanout....");
    }

    /**
     * 发送topic消息
     */
    @Test
    public void testTopics(){
        //2.发送消息
        rabbitTemplate.convertAndSend("spring_topic_exchange","heima.hehe.haha","spring topic....");
    }
}

2.3 配置整合

rabbitmq.properties

rabbitmq.host=172.16.98.133
rabbitmq.port=5672
rabbitmq.username=heima
rabbitmq.password=heima
rabbitmq.virtual-host=/itcast

spring-rabbitmq-consumer.xml

<?xml version="1.0" encoding="UTF-8"?>

    <!--加载配置文件-->

    <!-- 定义rabbitmq connectionFactory -->

2.4 编写消息监听器

public class SpringQueueListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        //打印消息
        System.out.println(new String(message.getBody()));
    }
}
