+# 支付宝充值赠送功能说明
+
+## 功能概述
+
+本功能实现了支付宝充值的自动赠送机制，根据充值金额自动计算并赠送相应的金额到用户钱包。
+
+## 赠送规则
+
+当前配置的赠送规则如下：
+
+| 充值金额 | 赠送金额 | 说明 |
+|---------|---------|------|
+| 1000元 | 50元 | 充值1000元及以上，赠送50元 |
+| 5000元 | 300元 | 充值5000元及以上，赠送300元 |
+| 10000元 | 800元 | 充值10000元及以上，赠送800元 |
+
+**注意**：赠送规则按充值金额从高到低匹配，即充值金额满足多个条件时，按最高档次的赠送金额计算。
+
+## 配置说明
+
+### 1. 配置文件位置
+
+- 主配置文件：`config.yaml`
+- 环境配置文件：`configs/env.*.yaml`
+
+### 2. 配置结构
+
+```yaml
+wallet:
+  default_credit_limit: 50.00
+  # 支付宝充值赠送配置
+  alipay_recharge_bonus:
+    - recharge_amount: 1000.00  # 充值1000元
+      bonus_amount: 50.00       # 赠送50元
+    - recharge_amount: 5000.00  # 充值5000元
+      bonus_amount: 300.00      # 赠送300元
+    - recharge_amount: 10000.00 # 充值10000元
+      bonus_amount: 800.00      # 赠送800元
+```
+
+### 3. 配置结构体
+
+```go
+type WalletConfig struct {
+    DefaultCreditLimit float64                    `mapstructure:"default_credit_limit"`
+    AliPayRechargeBonus []AliPayRechargeBonusRule `mapstructure:"alipay_recharge_bonus"`
+}
+
+type AliPayRechargeBonusRule struct {
+    RechargeAmount float64 `mapstructure:"recharge_amount"` // 充值金额
+    BonusAmount    float64 `mapstructure:"bonus_amount"`    // 赠送金额
+}
+```
+
+## 实现逻辑
+
+### 1. 赠送金额计算
+
+在 `calculateAlipayRechargeBonus` 函数中实现：
+
+```go
+func calculateAlipayRechargeBonus(rechargeAmount decimal.Decimal, walletConfig *config.WalletConfig) decimal.Decimal {
+    if walletConfig == nil || len(walletConfig.AliPayRechargeBonus) == 0 {
+        return decimal.Zero
+    }
+
+    // 按充值金额从高到低排序，找到第一个匹配的赠送规则
+    // 由于配置中规则是按充值金额从低到高排列的，我们需要反向遍历
+    for i := len(walletConfig.AliPayRechargeBonus) - 1; i >= 0; i-- {
+        rule := walletConfig.AliPayRechargeBonus[i]
+        if rechargeAmount.GreaterThanOrEqual(decimal.NewFromFloat(rule.RechargeAmount)) {
+            return decimal.NewFromFloat(rule.BonusAmount)
+        }
+    }
+
+    return decimal.Zero
+}
+```
+
+### 2. 充值成功处理
+
+在 `HandleAlipayPaymentSuccess` 方法中实现：
+
+1. **计算赠送金额**：根据充值金额计算应赠送的金额
+2. **创建赠送记录**：如果有赠送金额，创建一条赠送类型的充值记录
+3. **更新钱包余额**：将充值金额和赠送金额的总和添加到用户钱包
+
+```go
+// 计算充值赠送金额
+bonusAmount := calculateAlipayRechargeBonus(amount, &s.cfg.Wallet)
+totalAmount := amount.Add(bonusAmount)
+
+// 如果有赠送金额，创建赠送充值记录
+if bonusAmount.GreaterThan(decimal.Zero) {
+    giftRechargeRecord := entities.NewGiftRechargeRecord(rechargeRecord.UserID, bonusAmount, "充值活动赠送")
+    _, err = s.rechargeRecordRepo.Create(txCtx, *giftRechargeRecord)
+    if err != nil {
+        s.logger.Error("创建赠送充值记录失败", zap.Error(err))
+        return err
+    }
+}
+
+// 使用钱包聚合服务更新钱包余额（包含赠送金额）
+err = s.walletService.Recharge(txCtx, rechargeRecord.UserID, totalAmount)
+```
+
+## 数据库记录
+
+### 1. 充值记录表 (recharge_records)
+
+每次支付宝充值成功会产生两条记录：
+
+1. **支付宝充值记录**：
+   - `recharge_type`: "alipay"
+   - `amount`: 实际充值金额
+   - `status`: "success"
+
+2. **赠送充值记录**（如果有赠送）：
+   - `recharge_type`: "gift"
+   - `amount`: 赠送金额
+   - `notes`: "充值活动赠送"
+   - `status`: "success"
+
+### 2. 钱包余额
+
+钱包余额会更新为：`原余额 + 充值金额 + 赠送金额`
+
+## 测试用例
+
+### 1. 单元测试
+
+运行测试命令：
+```bash
+go test ./internal/domains/finance/services -v
+```
+
+测试覆盖的场景：
+- 充值500元，无赠送
+- 充值1000元，赠送50元
+- 充值2000元，赠送50元
+- 充值5000元，赠送300元
+- 充值8000元，赠送300元
+- 充值10000元，赠送800元
+- 充值15000元，赠送800元
+
+### 2. 配置测试
+
+运行配置测试：
+```bash
+go test ./internal/config -v
+```
+
+验证配置文件中的赠送规则是否正确加载。
+
+## 日志记录
+
+系统会记录详细的日志信息：
+
+```
+支付宝支付成功回调处理成功
+- user_id: 用户ID
+- recharge_amount: 充值金额
+- bonus_amount: 赠送金额
+- total_amount: 总金额（充值+赠送）
+- out_trade_no: 支付宝订单号
+- trade_no: 支付宝交易号
+- recharge_id: 充值记录ID
+- order_id: 支付宝订单ID
+```
+
+## 扩展说明
+
+### 1. 添加新的赠送规则
+
+在配置文件中添加新的规则：
+
+```yaml
+wallet:
+  alipay_recharge_bonus:
+    - recharge_amount: 1000.00
+      bonus_amount: 50.00
+    - recharge_amount: 5000.00
+      bonus_amount: 300.00
+    - recharge_amount: 10000.00
+      bonus_amount: 800.00
+    - recharge_amount: 20000.00  # 新增规则
+      bonus_amount: 2000.00      # 充值20000元赠送2000元
+```
+
+### 2. 修改赠送规则
+
+直接修改配置文件中的 `recharge_amount` 和 `bonus_amount` 值即可。
+
+### 3. 禁用赠送功能
+
+将配置文件中的 `alipay_recharge_bonus` 设置为空数组：
+
+```yaml
+wallet:
+  alipay_recharge_bonus: []
+```
+
+## 注意事项
+
+1. **事务保护**：所有数据库操作都在事务中执行，确保数据一致性
+2. **重复处理防护**：系统会检查订单状态，避免重复处理
+3. **精确计算**：使用 `decimal.Decimal` 进行金额计算，避免浮点数精度问题
+4. **日志记录**：详细记录所有操作，便于问题排查
+5. **配置热更新**：修改配置后需要重启服务才能生效
