application.yml
需要将publisher-confrems设为true,启动确认回调, 将 publisher-returns设为true 确认返回回调
rabbitmq配置类--RabbitConfig
第一部分, 定义队列
第二部分,设置一些消息处理策略

生产者
1 /** 2 * 生产者 3 * @author milicool 4 * Created on 2018/9/14 5 */ 6 @Component 7 public class Producer { 8 9 @Autowired 10 private RabbitTemplate rabbitTemplate; 11 12 /** 13 * 给hello队列发送消息 14 */ 15 public void send() { 16 for (int i =0; i< 100; i++) { 17 String msg = "hello, 序号: " + i; 18 System.out.println("Producer, " + msg); 19 rabbitTemplate.convertAndSend("queue-test", msg); 20 } 21 } 22 23 }
消费者
1 /** 2 * 消费者 3 * @author milicool 4 * Created on 2018/9/14 5 */ 6 @Component 7 public class Comsumer { 8 private Logger log = LoggerFactory.getLogger(Comsumer.class); 9 10 @RabbitListener(queues = "queue-test") 11 public void process(Message message, Channel channel) throws IOException { 12 // 采用手动应答模式, 手动确认应答更为安全稳定 13 channel.basicAck(message.getMessageProperties().getDeliveryTag(), true); 14 log.info("receive: " + new String(message.getBody())); 15 } 16 }
测试类
1 @RunWith(SpringRunner.class) 2 @SpringBootTest 3 public class RabbitmqApplicationTests { 4 5 @Autowired 6 private Producer producer; 7 8 @Test 9 public void contextLoads() { 10 producer.send(); 11 } 12 13 }
测试结果
测试结果太长,没有截取全部,可以查看到消费者接收到了全部消息,如果有的消息在没有接收完,消息将被持久化,下次启动时消费
