定义队列

@Configuration
public class RabbitMqConfig {

	// 普通字符串

}

发消息 - 生产

@Service
public class RabbitMqService {

	@Autowired
	UserService userService;

	@Autowired
	RabbitTemplate rabbitTemplate;

	public void sendOne(String queueName, String message){

		rabbitTemplate.convertAndSend(queueName, message);
	}

	public void sendTwo(String queueName){

		rabbitTemplate.convertAndSend(queueName, userService.findById(34));
	}
}

收消息 - 消费

@Component
public class RabbitMqComponent {

	@RabbitListener(queues = "one")
	public void listerOne(String obj){
		System.out.print(obj);
	}

	@RabbitListener(queues = "two")
	public void listerTwo(User user){
