# 会话记录 - Destructive Changes功能实现

## 现状

当前项目已经完成了元数据部署核心功能（REQ-010-8）和 Quick Deploy 功能（REQ-010-9）的实现，包括手动触发部署、异步部署执行、状态监控、部署历史记录、部署进度查询、部署取消功能和部署结果解析。现在需要实现 Destructive Changes 功能，支持部署时删除指定的元数据组件，使用 destructiveChanges.xml 配置删除规则。

## 目标

实现 Destructive Changes 功能，包括 destructiveChanges.xml 配置、Destructive Changes 部署、Destructive Changes 验证、Destructive Changes 历史记录、Destructive Changes 回滚。支持部署时删除指定的元数据组件，使用 destructiveChanges.xml 配置删除规则。

- 质疑：是否需要新增 DestructiveChangesException 异常类？
  - 替代方案：新增 DestructiveChangesException 异常类，与 DeployException 异常分开
  - 评估：Destructive Changes 的异常与普通部署的异常类似，可以新增 DestructiveChangesException 异常类，提供更精确的异常处理

## 结论

总结本次会话的结果，包括：

- 完成的工作：
  - 创建了 DestructiveChangesController 控制器，提供 6 个 RESTful API 接口
  - 创建了 IDestructiveChangesService 服务接口，定义 Destructive Changes 服务接口方法
  - 创建了 DestructiveChangesServiceImpl 服务实现，实现 Destructive Changes 服务接口方法
  - 创建了 IDestructiveChangesConfigService 服务接口，定义 Destructive Changes 配置服务接口方法
  - 创建了 DestructiveChangesConfigServiceImpl 服务实现，实现 Destructive Changes 配置服务接口方法
  - 创建了 DestructiveChangesXmlParser 工具类，验证 destructiveChanges.xml 格式
  - 创建了 DestructiveChangesXmlBuilder 工具类，构建 destructiveChanges.xml
  - 创建了 DestructiveChangeRule 实体类和 DestructiveChangeRuleMapper 接口
  - 创建了 DestructiveChangesConfigRequest、DestructiveChangesConfigResponse、DestructiveChangesValidateRequest、DestructiveChangesValidateResponse、DestructiveChangesDeployRequest、DestructiveChangesDeployResponse、DestructiveChangesHistoryResponse、DestructiveChangesRollbackRequest、DestructiveChangesRollbackResponse 等 DTO 类
  - 创建了 DestructiveChangesException 异常类
  - 复用了现有的 AsyncConfig 配置类

- 达成的目标：
  - 实现了 destructiveChanges.xml 配置功能，支持可视化编辑
  - 实现了 Destructive Changes 部署功能，支持删除指定的元数据组件
  - 实现了 Destructive Changes 验证功能，验证删除规则
  - 实现了 Destructive Changes 历史记录功能，支持分页查询和条件查询
  - 实现了 Destructive Changes 回滚功能，支持恢复被删除的元数据组件

- 后续的行动计划：
  - 更新 IMetadataApiService 接口，添加 deploy() 方法支持传入 destructiveChanges.xml
  - 更新 MetadataApiClient 实现，实现 deploy() 方法支持传入 destructiveChanges.xml
  - 更新 IMetadataApiService 接口，添加 rollback() 方法
  - 更新 MetadataApiClient 实现，实现 rollback() 方法
  - 创建数据库表 datai_destructive_change_rule
  - 编写单元测试和集成测试
  - 编写 API 文档和使用文档

- 需要跟进的事项：
  - 更新 Canvas，添加 Destructive Changes 相关的节点
  - 更新 CHANGELOG.md，记录本次变更
  - 创建复盘报告，总结本次迭代的经验和教训

## Design Update

- [x] 是否需要更新 Canvas? 是
- [ ] Authentication.canvas - 需要添加 Destructive Changes 相关的节点
- [ ] 其他 Canvas 文件: 无
