@Configuration
public class DirectConfig {

    public final  static String DIRECTQUEUE = "direct";
    @Bean
    public Queue queue(){
        return new Queue(DIRECTQUEUE);
    }
}

生产者

DirectSender

import com.gebiwangdaye.rabbitmq.config.DirectConfig;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class DirectSender {
    @Autowired
    private AmqpTemplate amqpTemplate;

    public void send(){
        String context = "发送消息 ================== direct";
        System.out.println(context);
        this.amqpTemplate.convertAndSend(DirectConfig.DIRECTQUEUE,context);
    }

@Component
@RabbitListener(queues = DirectConfig.DIRECTQUEUE)
public class DirectReceiver {
    @RabbitHandler
    public void process(String hello) {
        System.out.println("接收到消息 : " + hello);
    }
}

@SpringBootTest
public class RabbitmqApplicationTests {


    @Autowired
    private DirectSender directSender;

    @Test
    public void testDirectExchange(){
        for (int i = 0;i < 30;i++){
            directSender.send();
