配置文件

spring:
  application:
    name: test‐rabbitmq‐producer
rabbitmq:
  host: 127.0.0.1
  port: 5672
  username: guest   // rabbit 登录账号
  password: guest   // rabbit 登录密码
  virtualHost: /
server:
  port: 8888

配置类


@Configuration
public class RabbitMqConfig {
    public static final String QUEUE_NAME = "queue_test";   // 队列名
    public static final String EXCHANGE_NAME = "exchange_test"; // 交换机名
    public static final String ROUTING_KEY = "test.*";  // ROUTING_KEY  

    // 配置交换机
    @Bean(EXCHANGE_NAME)
    public Exchange exchange(){
        // ExchangeBuilder.fanoutExchange(EXCHANGE_NAME); fanout 类型交互机
        // ExchangeBuilder.directExchange(EXCHANGE_NAME); direct 类型交互机
        // ExchangeBuilder.headersExchange(EXCHANGE_NAME); headers 类型交互机
                                                         //durable(true)  持久化 消息队列重启后 交换机仍然存在
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();
    }

    // 配置队列
    @Bean(QUEUE_NAME)
    public Queue queue(){
        Queue queue = new Queue(QUEUE_NAME);
        return queue;
    }

    // 绑定队列到交换机
    @Bean
    public Binding binding(@Qualifier(QUEUE_NAME)Queue queue,@Qualifier(EXCHANGE_NAME)Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with(ROUTING_KEY).noargs();
    }
}

发送消息

@SpringBootTest
@RunWith(SpringRunner.class)
public class AppTest {
    @Autowired
    RabbitTemplate rabbitTemplate;
    @Test
    public void shouldAnswerWithTrue() {
        for (int i = 0; i < 10; i++){
            String message = "hello word" + i;
            rabbitTemplate.convertAndSend(RabbitMqConfig.EXCHANGE_NAME,"test.hehe",message);
            System.out.println("Send Message " + message);
        }
    }
}

消息接收者

从消息发送者copy RabbitMqConfig配置类
在这里插入图片描述

创建消息监听类

@Component
public class ReceiveHandler {
    // 监听队列
    @RabbitListener(queues = {RabbitMqConfig.QUEUE_NAME})
    public void listenerQueue(String msg){
        System.out.println(msg);
    }
}
