目前，我有简单的ChargeRequest和PaymentStatus作为我的实体，StripeService，ChargeController和CheckoutController作为我的控制器。
我尝试在**.bashrc**中设置环境变量：

STRIPE_SECRET_KEY=my_key

但是，仍然得到一个错误：

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'STRIPE_SECRET_KEY' in value "${STRIPE_SECRET_KEY}"

下面是 StripeService：

package com.edoyou.k2sbeauty.services.implementations;

import com.edoyou.k2sbeauty.entities.model.ChargeRequest;
import com.stripe.Stripe;
import com.stripe.exception.APIConnectionException;

@Service
public class StripeService {

  @Value("${STRIPE_SECRET_KEY}")
  private String secretKey;

  @PostConstruct
  public void init() {
    Stripe.apiKey = secretKey;
  }
  public Charge charge(ChargeRequest chargeRequest)
      throws AuthenticationException, InvalidRequestException,
      APIConnectionException, CardException, APIException, com.stripe.exception.AuthenticationException {
    Map<String, Object> chargeParams = new HashMap<>();
    chargeParams.put("amount", chargeRequest.getAmount());
    chargeParams.put("currency", chargeRequest.getCurrency());
    chargeParams.put("description", chargeRequest.getDescription());
    chargeParams.put("source", chargeRequest.getStripeToken());
    return Charge.create(chargeParams);
  }
}
