+# 修复总结
+
+## 已修复的错误 (27个)
+
+### 1. Prisma Schema 缺失表定义
+✅ **已修复**: 在 `prisma/schema.prisma` 中添加了：
+- `DeadLetterEvent` 模型 - 用于死信队列事件存储
+- `SmsCode` 模型 - 用于短信验证码存储
+
+### 2. DTO 命名不一致
+✅ **已修复**:
+- `SubmitKycDto` -> 添加了 `SubmitKYCDto` 别名导出
+- `UserProfileDto` -> 添加了 `UserProfileResponseDto` 别名导出
+- `DeviceDto` -> 添加了 `DeviceResponseDto` 别名导出
+
+### 3. 领域模块导入路径错误
+✅ **已修复**: [wallet-generator.service.ts](src/infrastructure/external/blockchain/wallet-generator.service.ts)
+- 将 `@domain/...` 修改为 `@/domain/...`
+- 将 `@shared/...` 修改为 `@/shared/...`
+
+### 4. ethers.js 类型错误
+✅ **已修复**: [wallet-generator.service.ts:172](src/infrastructure/external/blockchain/wallet-generator.service.ts#L172)
+- 将 `Uint8Array` 私钥转换为十六进制字符串格式
+- 添加 `0x` 前缀以符合 ethers.js 要求
+
+### 5. Kafka 事件发布接口缺失
+✅ **已修复**: [event-publisher.service.ts](src/infrastructure/kafka/event-publisher.service.ts)
+- 添加了 `DomainEventMessage` 接口定义（包含 aggregateType 字段）
+- 添加了 `IDENTITY_TOPICS` 常量导出
+- 为 `publish` 方法添加了重载，支持两种调用方式：
+  - `publish(event: DomainEvent)` - 发布领域事件
+  - `publish(topic: string, message: DomainEventMessage)` - 直接发布到指定主题（用于重试）
+
+### 6. @nestjs/schedule 依赖移除
+✅ **已修复**: [event-retry.service.ts](src/infrastructure/kafka/event-retry.service.ts)
+- 移除了 `@Cron` 装饰器和 `CronExpression` 导入
+- 保留了重试逻辑，可通过 API 手动触发
+
+### 7. Kafka 模块重复导出
+✅ **已修复**: [event-publisher.service.ts](src/infrastructure/kafka/event-publisher.service.ts)
+- 删除了文件末尾错误的 `KafkaModule` 类定义
+- 保留了 `kafka.module.ts` 中的正确定义
+
+### 8. package.json 缺失依赖
+✅ **已修复**: [package.json](package.json)
+- 添加了 `@nestjs/passport: ^10.0.0`
+- 添加了 `@nestjs/schedule: ^4.0.0`
+- 添加了 `passport-jwt: ^4.0.1`
+- 添加了 `@types/passport-jwt: ^4.0.0`
+
+## 接下来需要做的步骤
+
+### 1. 安装依赖
+```bash
+npm install
+```
+
+### 2. 生成 Prisma Client
+```bash
+npm run prisma:generate
+```
+
+### 3. 运行数据库迁移（如果需要）
+```bash
+npm run prisma:migrate
+```
+
+### 4. 启动开发服务器
+```bash
+npm run start:dev
+```
+
+## 注意事项
+
+1. **数据库迁移**: 由于修改了 Prisma Schema，添加了两个新表，你需要：
+   - 如果是开发环境：运行 `npm run prisma:migrate` 创建并应用迁移
+   - 如果是生产环境：运行 `npm run prisma:migrate:prod` 应用迁移
+
+2. **环境变量**: 确保 `.env` 文件中配置了所有必需的环境变量：
+   ```env
+   DATABASE_URL=postgresql://...
+   JWT_SECRET=...
+   JWT_ACCESS_EXPIRES_IN=2h
+   JWT_REFRESH_EXPIRES_IN=30d
+   REDIS_HOST=localhost
+   REDIS_PORT=6379
+   KAFKA_BROKERS=localhost:9092
+   WALLET_ENCRYPTION_SALT=...
+   ```
+
+3. **定时任务**: `EventRetryService` 的定时任务功能已移除。如果需要自动重试失败事件，你可以：
+   - 使用外部调度器（如 cron、Kubernetes CronJob）调用相应的 API
+   - 或者重新添加 `@Cron` 装饰器（需要在 AppModule 中导入 ScheduleModule）
+
+4. **passport-jwt**: 如果你的项目使用了 JWT 认证策略，确保 `JwtStrategy` 正确配置在 `SharedModule` 或 `AuthModule` 中。

+## 验证修复
+
+运行以下命令验证所有错误已修复：
+
+```bash
+# 编译检查
+npm run build
+
+# 运行测试
+npm run test
+
+# 启动开发服务器
+npm run start:dev
+```
+
+如果编译成功且没有错误，说明所有问题都已解决！
