RabbitMQConfiguration.java
package com.example.demo; import org.springframework.amqp.core.Queue; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class RabbitMQConfiguration { private static final String QUEUE_SIMPLE_NAME = "hello"; // 队列 @Bean public Queue queue(){ return new Queue(QUEUE_SIMPLE_NAME); } }
创建消息的消费者 Consumer,java
package com.example.demo; import org.springframework.amqp.rabbit.annotation.RabbitHandler; import org.springframework.amqp.rabbit.annotation.RabbitListener; import org.springframework.stereotype.Component; /** * @author: DevanYan * @create: 2019-05-28 11:46 */ //消息的消费者 @Component @RabbitListener(queues = "hello") public class Consumer { @RabbitHandler public void use(String message) { System.out.println("消费了一条消息 : " + message); } }
创建消息的生产者 Creater.java
package com.example.demo; import org.springframework.amqp.core.AmqpTemplate; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; /** * @author: DevanYan * @create: 2019-05-28 11:47 */ // 消息的生产者 @Component public class Creater { @Autowired private AmqpTemplate amqpTemplate; public void create(){ String message = "Hello RabbitMQ !"; amqpTemplate.convertAndSend("hello", message); System.out.println("创建了一条消息 : " + message); } }
编写测试类
package com.example.demo; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; @RunWith(SpringRunner.class) @SpringBootTest public class DemoApplicationTests { @Autowired Creater creater; @Test public void creatertest(){ creater.create(); } }
