in order to be compatible with a variety of businesses, I want to use some design patterns in the project for ease of management.
for example, I need to create a user and return userid,. Each business is created in a different way.
I chose Adapter pattern, but I found that new classes are often needed under the management of springmvc, and at this time, some spring tags in this class are invalid.
here is the code I used to create the user:

Interface

public interface IPlatformSendPay {

    public abstract Object sendPayInA(Object object);
    public abstract Object sendPayInB(Object object);

}

parent

public class PlatformSendPay  {
    private Object obj;

    @Resource
    private OpenPaymentDao openPaymentDao;

    public PlatformSendPay(Object obj) {
        this.obj = obj;
    }

    public Object getUserIdInA(){
        JidouOrderData jidouOrderData = (JidouOrderData) obj;

        int stationId = jidouOrderData.getStation_id();
        //openPaymentDao@ResourcePlatformSendPayspring
        Integer userId = openPaymentDao.getIdentifyUser(jidouOrderData.getIdentifyId(), "1000000013");
        if (ObjectUtils.isEmpty(userId)){
           //todo:
        }
        return userId;
    }


}

subclass

public class SendPay extends PlatformSendPay implements IPlatformSendPay{

    public SendPay(Object obj) {
        super(obj);
    }

    @Override
    public Object sendPayInA(Object object) {
        return getUserIdInA();
    }
    
    @Override
    public Object sendPayInB(Object object) {
        return getUserIdInB();
    }

}

this is my implementation class, the @ Service tag in springmvc

  //
  SendPay sendPay = new SendPay(jidouOrderData);
  int userId = (int) sendPay.getUserIdInA();

  //
  SendPay sendPay = new SendPay(JdOrderData);
  int userId = (int) sendPay.getUserIdInB();

questions

1.PlatformSendPay Why is spring binding unsuccessful? How can I bind successfully? In
2.springmvc, do you use such design patterns as little as possible? In the method in the object, the variable used has a spring tag, but in the case of new, will this be invalid?
