#### 1.1.3属性配置文件 ####

在resources目录下面创建rabbitmq.properties属性配置文件

rabbitmq.host=192.168.137.118
    rabbitmq.port=5672
    rabbitmq.username=admin
    rabbitmq.password=123456
    rabbitmq.virtual-host=/

#### 1.1.4spring整合配置文件 ####

    </beans>

#### 1.1.5发送消息 ####

@RunWith注解的作用:让测试在spring容器环境下执行，如果测试类没有这个注解，会导致service，dao等注入失败

@RunWith(SpringRunner.class)
    @ContextConfiguration(locations = "classpath:spring-rabbitmq.xml")
    public class ProducerTest {
        
        @Autowired
        private RabbitTemplate rabbitTemplate;
        @Test
          /**
         * 只发队列消息
         * 默认交换机类型为 direct
         * 交换机的名称为空,路由键为队列的名称
         */
        
        public void queueTest(){
        
            //路由键与队列同名
            rabbitTemplate.convertAndSend("spring_queue", "只发队列spring_queue的消息。");
        }
    }

### 1.2消费者 ###

#### 1.2.1创建消费者工程 spring-rabbitmq-consumer ####

#### 1.2.2引入依赖 ####

    rabbitmq.username=admin
    rabbitmq.password=123456
