我正在做一件私人事情,我面临一个需要其他意见的问题。我有下面的代码,我想在其中创建一个工厂模式的新实例
PaymentStrategy
:
界面
public interface PaymentStrategy {
Optional<Payment> pay(String payerAccountNumber,
String sellerAccountNumber,
ProductOrder[] productOrder
);
}
EmployeePaymentStrategy
public class EmployeePaymentStrategy implements PaymentStrategy {
private final ProfileRemoteProvider profileRemoteProvider;
private final PaymentValidator paymentValidator;
@Autowired
public EmployeePaymentStrategy(ProfileRemoteProvider profileRemoteProvider,
PaymentValidator paymentValidator) {
this.profileRemoteProvider = profileRemoteProvider;
this.paymentValidator = paymentValidator;
}
@Override
public Optional<Payment> pay(String payerAccountNumber,
String sellerAccountNumber,
ProductOrder[] productOrder) {
...
}
}
我想知道如何处理工厂类中的依赖项。

工厂模式是解决问题的最佳方式吗
PaymentStrategyFactory
问题出在哪里
public class PaymentStrategyFactory {
private PaymentStrategyFactory() {
}
public static PaymentStrategy getPaymentStrategy(AccountType payerAccountType,
AccountType sellerAccountType) {
if (sellerAccountType == AccountType.COMPANY) {
switch (payerAccountType) {
case EMPLOYEE:
return new EmployeePaymentStrategy(...); //TODO
case BASIC_USER:
return ...
default:
//this exception is throw when a payer account type is unknown
throw new RuntimeException("exception type will be more specific");
}
}
//This exception is throw when a seller account type is not a seller
throw new RuntimeException("exception type will be more specific");
}
}
