    //配置Exchange
    @Bean
    public DirectExchange directExchange() {
        return new DirectExchange("mydirect");
    }

    // 绑定交换机与队列
    @Bean
    public Binding getMyqueue(DirectExchange directExchange) {
        Queue queue = new Queue("directqueue");
        //mydirect --  交换机Name；key -- 消费用的key
        return BindingBuilder.bind(queue).to(directExchange).with("key");
    }

}

发送消息

@Service
public class RabbitmqProducerService {

    @Autowired
    private AmqpTemplate amqpTemplate;

    public void amqpTemplateTest(){
        String message = UUID.randomUUID().toString().substring(0, 6);
        //mydirect --  交换机Name；key -- 发送的key
        amqpTemplate.convertAndSend("mydirect","key.11",message);
        System.out.println("发送完成");
    }
}

接收消息

@Component
public class RabbitmqListener {

    @RabbitListeners({@RabbitListener(queues = "directqueue")})
    public void reveiceMessage(String msg, Channel channel, Message message) {
        System.out.println(msg);
        System.out.println(channel);
        System.out.println(message);
    }
