Spring整合RabbitMQ-灵析社区
开着皮卡写代码1.简单消息模式
1.1生产者
1.1.1 创建生产者工程 spring-rabbitmq-producer

@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。");
}
