spring paypal api上下文问题

Question

在春季启动应用程序中集成贝宝时，我遇到了这个问题

    Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

***************************
APPLICATION FAILED TO START
***************************

Description:

Field apiContext in com.bookstore.service.impl.PaypalService required a bean of type 'com.paypal.base.rest.APIContext' that could not be found.


Action:

Consider defining a bean of type 'com.paypal.base.rest.APIContext' in your configuration.

我的主要看起来像

@SpringBootApplication
@EnableAutoConfiguration
@Configuration
@ComponentScan
public class BookstoreAngularApplication implements CommandLineRunner {

错误指向我使用paypal的api上下文的服务

import com.paypal.api.payments.Transaction;
import com.paypal.base.rest.APIContext;
import com.paypal.base.rest.PayPalRESTException;
    @Autowired
        private APIContext apiContext;

        public Payment createPayment(
                Double total, 
                String currency, 
                PaypalPaymentMethod method, 
                PaypalPaymentIntent intent, 
                String description, 
                String cancelUrl, 
                String successUrl) throws PayPalRESTException{
            Amount amount = new Amount();
            amount.setCurrency(currency);
            amount.setTotal(total.toString());

            Transaction transaction = new Transaction();
            transaction.setDescription(description);
            transaction.setAmount(amount);

            List<Transaction> transactions = new ArrayList<>();
            transactions.add(transaction);

            Payer payer = new Payer();
            payer.setPaymentMethod(method.toString());

            Payment payment = new Payment();
            payment.setIntent(intent.toString());
            payment.setPayer(payer);
            payment.setTransactions(transactions);
            RedirectUrls redirectUrls = new RedirectUrls();
            redirectUrls.setCancelUrl(cancelUrl);
            redirectUrls.setReturnUrl(successUrl);
            payment.setRedirectUrls(redirectUrls);

            return payment.create(apiContext);
        }

        public Payment executePayment(String paymentId, String payerId) throws PayPalRESTException{
            Payment payment = new Payment();
            payment.setId(paymentId);
            PaymentExecution paymentExecute = new PaymentExecution();
            paymentExecute.setPayerId(payerId);
            return payment.execute(apiContext, paymentExecute);
        }

我有运行 paypal sdk 的项目工作正常，但是当我将它添加到我的应用程序时，我对 paypal api 上下文的这个错误感到恶心

Answer 1

这是因为我放置配置文件的包的名称必须像 base-packages。* 我在开始时输入了一个快速名称我现在修复它并使其成为它扫描的其他包名称和工作正常

Answer 2

我以前从未使用过com.paypal.base.rest.APIContext，但您的错误消息表明您需要APIContext 类型的bean，以便可以自动装配。

考虑定义一个“com.paypal.base.rest.APIContext”类型的bean 你的配置。

尝试将 bean 添加到您的配置类（或 xml 文件，如果您仍在使用基于 .xml 的配置）。阅读com.paypal.base.rest.APIContextdocumentation 我猜你需要类似的东西：

@Configuration
public class AppConfiguration {

    @Bean
    public APIContext apiContext() {
        APIContext apiContext = new APIContext("yourClientID", "yourClientSecret", "yourMode");
        return apiContext;
    }

试试这个，看看是否有效。请记住，AppConfiguration 必须放在BookstoreAngularApplication 的子包中，这样才能加载它。这是example。

稍后，从配置文件中读取"yourClientID", "yourClientSecret", "yourMode"，而不是对其进行硬编码。
