以下为基于Spring Boot的JAVA海外短剧国际版源码核心模块代码示例，涵盖多语言支持、OSS集成、支付网关、区域适配等关键功能：

1. 多语言国际化配置（I18n）

java

// 自定义LocaleResolver实现动态语言切换
@Component
public class MyLocaleResolver implements LocaleResolver {
    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        String language = request.getParameter("lang");
        Locale locale = Locale.getDefault();
        if(StringUtils.isNotEmpty(language)){
            locale = new Locale(language.split("_")[0], language.split("_")[1]);
        }
        return locale;
    }
    @Override
    public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {}
}

// 配置类启用国际化
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    @Bean
    public LocaleResolver localeResolver() {
        return new MyLocaleResolver();
    }
}

2. 阿里云OSS集成工具类

java

@Component
public class AliyunOssUtil {
    @Value("${aliyun.oss.endpoint}")
    private String endpoint;
    @Value("${aliyun.oss.accessKeyId}")
    private String accessKeyId;
    @Value("${aliyun.oss.accessKeySecret}")
    private String accessKeySecret;
    @Value("${aliyun.oss.bucketName}")
    private String bucketName;

    public String uploadVideo(MultipartFile file) throws IOException {
        String originalFilename = file.getOriginalFilename();
        String fileExt = originalFilename.substring(originalFilename.lastIndexOf("."));
        String objectName = "short-drama/" + UUID.randomUUID() + fileExt;
        
        try (OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret)) {
            PutObjectResult result = ossClient.putObject(bucketName, objectName, file.getInputStream());
            return "https://" + bucketName + "." + endpoint + "/" + objectName;
        }
    }

    // 生成带签名的临时访问URL（防盗链）
    public String generateSignedUrl(String objectName, Date expiration) {
        try (OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret)) {
            return ossClient.generatePresignedUrl(bucketName, objectName, expiration).toString();
        }
    }
}

3. 多支付网关集成示例（PayPal）

java

@Service
public class PayPalPaymentService {
    @Value("${paypal.client.id}")
    private String clientId;
    @Value("${paypal.client.secret}")
    private String clientSecret;
    @Value("${paypal.mode}")
    private String mode;

    public Payment createPayment(BigDecimal amount, String currency, String returnUrl, String cancelUrl) 
        throws PayPalAPIException {
        
        ApiContext apiContext = new ApiContext(new OAuthTokenCredential(clientId, clientSecret).getAccessToken());
        apiContext.setConfigurationMap(getConfigMap());

        Payment payment = new Payment();
        payment.setIntent("sale");
        payment.setPayer(new Payer().setPaymentMethod("paypal"));
        
        RedirectUrls redirectUrls = new RedirectUrls();
        redirectUrls.setReturnUrl(returnUrl);
        redirectUrls.setCancelUrl(cancelUrl);
        payment.setRedirectUrls(redirectUrls);
        
        PaymentUnit amountUnit = new PaymentUnit().currency(currency).value(amount.toString());
        Transaction transaction = new Transaction().amount(amountUnit);
        payment.addTransaction(transaction);
        
        return payment.create(apiContext);
    }

    private Map<String, String> getConfigMap() {
        Map<String, String> config = new HashMap<>();
        config.put("mode", mode);
        return config;
    }
}

4. 区域敏感内容过滤模块

java

@Service
public class ContentFilterService {
    private final RestTemplate restTemplate;

    @PostConstruct
    public void init() {
        restTemplate = new RestTemplateBuilder()
            .setConnectTimeout(Duration.ofSeconds(5))
            .build();
    }

    public boolean isContentCompliant(String content, String region) {
        String endpoint = "https://api.content-filter.com/v1/check";
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        
        JSONObject requestBody = new JSONObject();
        requestBody.put("content", content);
        requestBody.put("region", region);
        
        HttpEntity<String> request = new HttpEntity<>(requestBody.toString(), headers);
        ResponseEntity<JSONObject> response = restTemplate.postForEntity(endpoint, request, JSONObject.class);
        
        return response.getBody().getBoolean("compliant");
    }
}

5. 动态CDN配置服务

java

@Service
public class CdnConfigService {
    private final AliyunOssUtil ossUtil;
    private final RestTemplate restTemplate;

    public void updateCdnCacheRules(String region) {
        String cdnEndpoint = "https://cdn.aliyuncs.com/v2/cache_rules";
        HttpHeaders headers = new HttpHeaders();
        headers.set("Authorization", "Bearer " + getCdnToken());
        
        JSONObject rule = new JSONObject();
        rule.put("region", region);
        rule.put("ttl", region.equals("CN") ? 3600 : 86400); // 不同地区差异化缓存策略
        
        HttpEntity<String> request = new HttpEntity<>(rule.toString(), headers);
        restTemplate.put(cdnEndpoint, request);
    }

    private String getCdnToken() {
        // 调用阿里云STS服务获取临时凭证
        return StsClient.getToken();
    }
}

6. 国际化消息源配置

properties

# messages_en_US.properties
drama.title=Popular Short Drama
payment.success=Payment successful!
error.404=Content not available in your region

# messages_zh_CN.properties
drama.title=热门短剧
payment.success=支付成功！
error.404=您所在地区无法访问该内容

# messages_ja_JP.properties
drama.title=人気短編ドラマ
payment.success=決済が完了しました
error.404=お客様の地域ではコンテンツをご利用いただけません
