如何在Java中通过Billing API区分GCP原生服务与Marketplace采购产品

核心判断逻辑基于Billing API返回的Service和Sku对象特征字段，以下是具体规则和Java实现代码：

判断规则 #

• 服务商标识：原生服务的service.providerName固定为"Google"，Marketplace产品的该字段为第三方厂商名称（如"Datadog"、"MongoDB Inc."）
• 资源分类：Marketplace产品的service.category.resourceFamily通常为"Marketplace"
• SKU描述：部分Marketplace产品的SKU描述会包含"Marketplace"关键词（可作为辅助判断）

Java代码示例 #

首先添加Maven依赖：

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-billing</artifactId>
    <version>3.21.0</version> <!-- 替换为最新版本 -->
</dependency>

实现代码：

import com.google.cloud.billing.v1.BillingAccount;
import com.google.cloud.billing.v1.BillingClient;
import com.google.cloud.billing.v1.ListBillingAccountsRequest;
import com.google.cloud.billing.v1.ProjectBillingInfo;
import com.google.cloud.billing.v1.Sku;
import com.google.cloud.billing.v1.ListSkusRequest;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class MarketplaceProductLister {

    public static void main(String[] args) throws IOException {
        // 初始化Billing客户端
        try (BillingClient billingClient = BillingClient.create()) {
            // 获取所有账单账号
            ListBillingAccountsRequest accountRequest = ListBillingAccountsRequest.newBuilder()
                    .setPageSize(100)
                    .build();
            
            for (BillingAccount account : billingClient.listBillingAccounts(accountRequest).iterateAll()) {
                System.out.printf("=== 账单账号: %s ===%n", account.getName());
                
                // 获取该账单账号关联的所有项目
                for (ProjectBillingInfo projectInfo : billingClient.listProjectBillingInfo(account.getName()).iterateAll()) {
                    String projectId = projectInfo.getProjectId();
                    System.out.printf("--- 项目: %s ---%n", projectId);
                    
                    // 获取该项目对应的Marketplace产品SKUs
                    List<Sku> marketplaceSkus = getMarketplaceSkus(billingClient, account.getName());
                    if (marketplaceSkus.isEmpty()) {
                        System.out.println("无Marketplace采购产品");
                        continue;
                    }
                    
                    // 去重并输出产品列表
                    List<String> productNames = new ArrayList<>();
                    for (Sku sku : marketplaceSkus) {
                        String product = String.format("%s (厂商: %s)", 
                                sku.getService().getDisplayName(), 
                                sku.getService().getProviderName());
                        if (!productNames.contains(product)) {
                            productNames.add(product);
                        }
                    }
                    
                    System.out.println("Marketplace产品列表:");
                    productNames.forEach(name -> System.out.println("- " + name));
                }
            }
        }
    }

    private static List<Sku> getMarketplaceSkus(BillingClient billingClient, String billingAccountName) {
        List<Sku> skus = new ArrayList<>();
        ListSkusRequest skuRequest = ListSkusRequest.newBuilder()
                .setParent(billingAccountName)
                .setPageSize(1000)
                .build();
        
        for (Sku sku : billingClient.listSkus(skuRequest).iterateAll()) {
            // 核心判断：服务商非Google，或资源分类为Marketplace
            boolean isMarketplace = !"Google".equals(sku.getService().getProviderName()) 
                    || "Marketplace".equals(sku.getService().getCategory().getResourceFamily());
            
            if (isMarketplace) {
                skus.add(sku);
            }
        }
        return skus;
    }
}

注意事项 #

• 运行代码的服务账号需要拥有roles/billing.viewer角色，确保能访问账单和项目关联信息
• 若需精准关联单个项目，可结合Cloud Asset API获取项目ID列表，再通过ProjectBillingInfo匹配对应账单账号
• 部分旧版Marketplace产品分类标识不明显，建议优先以providerName作为判断依据
