鸿蒙金融理财全栈项目：风险控制、合规审计与产品创新

风险预警处理

当检测到风险时，系统会生成预警记录。用户点击列表项即可处理预警，后端返回处理结果后更新 UI。

// entry/src/main/ets/utils/RiskWarningUtil.ets
import warning from '@ohos.warning';

export class RiskWarningUtil {
  private static instance: RiskWarningUtil | null = null;
  private warningHelper: warning.WarningHelper | null = null;

  static getInstance(): RiskWarningUtil {
    if (!RiskWarningUtil.instance) {
      RiskWarningUtil.instance = new RiskWarningUtil();
    }
    return RiskWarningUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.warningHelper) {
      this.warningHelper = warning.createWarningHelper();
    }
  }

  async issueRiskWarning(): Promise<Array<warning.RiskWarning>> {
    if (!this.warningHelper) return [];
    const result = await this.warningHelper.issueRiskWarning();
    return result;
  }

  async handleRiskWarning(warningId: number): Promise<warning.RiskWarningResult> {
    if (!this.warningHelper) return null;
    const result = await this.warningHelper.handleRiskWarning(warningId);
    return result;
  }
}

二、合规审计实战

合规是金融产品的生命线。我们需要实现检查、审计和报告生成的完整链路。

2.1 合规检查与审计

合规检查侧重于规则匹配，而合规审计更偏向于流程追溯。工具类设计保持一致，方便统一调用。

// entry/src/main/ets/utils/ComplianceCheckUtil.ets
import compliance from '@ohos.compliance';

export class ComplianceCheckUtil {
  private static instance: ComplianceCheckUtil | null = null;
  private complianceHelper: compliance.ComplianceHelper | null = null;

  static getInstance(): ComplianceCheckUtil {
    if (!ComplianceCheckUtil.instance) {
      ComplianceCheckUtil.instance = new ComplianceCheckUtil();
    }
    return ComplianceCheckUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.complianceHelper) {
      this.complianceHelper = compliance.createComplianceHelper();
    }
  }

  async checkFinancialProductCompliance(productId: number): Promise<compliance.ComplianceCheckResult> {
    if (!this.complianceHelper) return null;
    const result = await this.complianceHelper.checkFinancialProductCompliance(productId);
    return result;
  }

  async getFinancialProductComplianceReport(productId: number): Promise<compliance.ComplianceReport> {
    if (!this.complianceHelper) return null;
    const result = await this.complianceHelper.getFinancialProductComplianceReport(productId);
    return result;
  }
}

2.2 合规报告生成

报告生成需要聚合历史数据。这里通过 ID 查询特定产品的合规档案，支持下载功能。

// entry/src/main/ets/utils/ComplianceReportUtil.ets
import report from '@ohos.report';

export class ComplianceReportUtil {
  private static instance: ComplianceReportUtil | null = null;
  private reportHelper: report.ReportHelper | null = null;

  static getInstance(): ComplianceReportUtil {
    if (!ComplianceReportUtil.instance) {
      ComplianceReportUtil.instance = new ComplianceReportUtil();
    }
    return ComplianceReportUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.reportHelper) {
      this.reportHelper = report.createReportHelper();
    }
  }

  async generateFinancialProductComplianceReport(productId: number): Promise<report.ComplianceReport> {
    if (!this.reportHelper) return null;
    const result = await this.reportHelper.generateFinancialProductComplianceReport(productId);
    return result;
  }

  async downloadFinancialProductComplianceReport(productId: number): Promise<report.ComplianceReportDownloadResult> {
    if (!this.reportHelper) return null;
    const result = await this.reportHelper.downloadFinancialProductComplianceReport(productId);
    return result;
  }
}

三、产品创新实战

产品创新模块允许运营人员配置新产品参数，并进行优化建议分析。

3.1 新产品开发

通过表单收集产品名称、预期收益率等关键信息，提交后调用创新接口。

// entry/src/main/ets/utils/ProductInnovationUtil.ets
import innovation from '@ohos.innovation';

export class ProductInnovationUtil {
  private static instance: ProductInnovationUtil | null = null;
  private innovationHelper: innovation.InnovationHelper | null = null;

  static getInstance(): ProductInnovationUtil {
    if (!ProductInnovationUtil.instance) {
      ProductInnovationUtil.instance = new ProductInnovationUtil();
    }
    return ProductInnovationUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.innovationHelper) {
      this.innovationHelper = innovation.createInnovationHelper();
    }
  }

  async developNewFinancialProduct(productData: innovation.FinancialProductData): Promise<innovation.ProductInnovationResult> {
    if (!this.innovationHelper) return null;
    const result = await this.innovationHelper.developNewFinancialProduct(productData);
    return result;
  }

  async optimizeExistingFinancialProduct(productId: number, productData: innovation.FinancialProductData): Promise<innovation.ProductInnovationResult> {
    if (!this.innovationHelper) return null;
    const result = await this.innovationHelper.optimizeExistingFinancialProduct(productId, productData);
    return result;
  }
}

3.2 推广与优化

产品上线后，需持续跟踪效果。优化工具提供建议列表，推广工具负责触达用户。

// entry/src/main/ets/utils/ProductPromotionUtil.ets
import promotion from '@ohos.promotion';

export class ProductPromotionUtil {
  private static instance: ProductPromotionUtil | null = null;
  private promotionHelper: promotion.PromotionHelper | null = null;

  static getInstance(): ProductPromotionUtil {
    if (!ProductPromotionUtil.instance) {
      ProductPromotionUtil.instance = new ProductPromotionUtil();
    }
    return ProductPromotionUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.promotionHelper) {
      this.promotionHelper = promotion.createPromotionHelper();
    }
  }

  async promoteFinancialProduct(productId: number): Promise<promotion.ProductPromotionResult> {
    if (!this.promotionHelper) return null;
    const result = await this.promotionHelper.promoteFinancialProduct(productId);
    return result;
  }

  async getFinancialProductPromotionReport(productId: number): Promise<promotion.ProductPromotionReport> {
    if (!this.promotionHelper) return null;
    const result = await this.promotionHelper.getFinancialProductPromotionReport(productId);
    return result;
  }
}

四、部署与验证

完成代码编写后，需在 DevEco Studio 中进行编译和部署。

1. 修改配置：在 entry/src/main/module.json5 中添加必要的权限声明，确保风控和审计模块能正常访问系统能力。
2. 编译构建：点击 Build → Build HAP，生成安装包。
3. 真机测试：连接设备，运行应用并逐一验证各功能模块的交互逻辑。

重点检查风险评估是否准确、合规报告生成时间是否符合预期、以及产品创新数据的持久化情况。
