配置整合

创建spring-rabbitmq-producer\src\main\resources\properties\rabbitmq.properties连接参数等配置文件；

rabbitmq.host=192.168.12.135
rabbitmq.port=5672
rabbitmq.username=heima
rabbitmq.passWord=heima
rabbitmq.virtual-host=/itcast

创建 spring-rabbitmq-producer\src\main\resources\spring\spring-rabbitmq.xml 整合配置文件；

发送消息

创建测试文件 spring-rabbitmq-producer\src\test\java\com\itheima\rabbitmq\ProducerTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/spring-rabbitmq.xml")
public class ProducerTest {
    @Autowired
    private RabbitTemplate rabbitTemplate;
    
    @Test
    public void queueTest(){
        //路由键与队列同名
        rabbitTemplate.convertAndSend("spring_queue", "只发队列spring_queue的消息。");
    }
    
    @Test
    public void fanoutTest(){
        
        rabbitTemplate.convertAndSend("spring_fanout_exchange", "", "发送到spring_fanout_exchange交换机的广播消息");
    }
    
    @Test
    public void topicTest(){
        
        rabbitTemplate.convertAndSend("spring_topic_exchange", "heima.bj", "发送到spring_topic_exchange交换机heima.bj的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "heima.bj.1", "发送到spring_topic_exchange交换机heima.bj.1的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "heima.bj.2", "发送到spring_topic_exchange交换机heima.bj.2的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "itcast.cn", "发送到spring_topic_exchange交换机itcast.cn的消息");
    }
}

                    message.getMessageProperties().getReceivedExchange(),
                    message.getMessageProperties().getReceivedRoutingKey(),
                    message.getMessageProperties().getConsumerQueue(),
                    msg);
