refactor:项目架构重构和命名规范化

- 统一文件命名为snake_case格式(kebab-case  snake_case)
- 重构zulip模块为zulip_core,明确Core层职责
- 重构user-mgmt模块为user_mgmt,统一命名规范
- 调整模块依赖关系,优化架构分层
- 删除过时的文件和目录结构
- 更新相关文档和配置文件

本次重构涉及大量文件重命名和模块重组,
旨在建立更清晰的项目架构和统一的命名规范。

# Users 用户数据管理模块
Users 是应用的核心用户数据管理模块,提供完整的用户数据存储、查询、更新和删除功能,支持数据库和内存两种存储模式,具备统一的异常处理、日志记录和性能监控能力。
## 用户数据操作
### create()
创建新用户记录,支持数据验证和唯一性检查。
### createWithDuplicateCheck()
创建用户前进行完整的重复性检查确保用户名、邮箱、手机号、GitHub ID的唯一性。
### findAll()
分页查询所有用户,支持排序和软删除过滤。
### findOne()
根据用户ID查询单个用户支持包含已删除用户的查询。
### findByUsername()
根据用户名查询用户,支持精确匹配查找。
### findByEmail()
根据邮箱地址查询用户,用于登录验证和账户找回。
### findByGithubId()
根据GitHub ID查询用户支持第三方OAuth登录。
### update()
更新用户信息,包含唯一性约束检查和数据验证。
### remove()
物理删除用户记录,数据将从存储中永久移除。
### softRemove()
软删除用户,设置删除时间戳但保留数据记录。
## 高级查询功能
### search()
根据关键词在用户名和昵称中进行模糊搜索,支持大小写不敏感匹配。
### findByRole()
根据用户角色查询用户列表,支持权限管理和用户分类。
### createBatch()
批量创建用户,支持事务回滚和错误处理。
### count()
统计用户数量,支持条件查询和数据分析。
### exists()
检查用户是否存在,用于快速验证和业务逻辑判断。
## 使用的项目内部依赖
### UserStatus (来自 business/user-mgmt/enums/user-status.enum)
用户状态枚举,定义用户的激活、禁用、待验证等状态值。
### CreateUserDto (本模块)
用户创建数据传输对象,提供完整的数据验证规则和类型定义。
### Users (本模块)
用户实体类,映射数据库表结构和字段约束。
### BaseUsersService (本模块)
用户服务基类,提供统一的异常处理、日志记录和数据脱敏功能。
## 核心特性
### 双存储模式支持
- 数据库模式使用TypeORM连接MySQL适用于生产环境
- 内存模式使用Map存储适用于开发测试和故障降级
- 动态模块配置通过UsersModule.forDatabase()和forMemory()灵活切换
### 完整的CRUD操作
- 支持用户的创建、查询、更新、删除全生命周期管理
- 提供批量操作和高级查询功能
- 软删除机制保护重要数据
### 数据完整性保障
- 唯一性约束检查用户名、邮箱、手机号、GitHub ID
- 数据验证使用class-validator进行输入验证
- 事务支持:批量操作支持回滚机制
### 统一异常处理
- 继承BaseUsersService的统一异常处理机制
- 详细的错误分类和用户友好的错误信息
- 完整的日志记录和性能监控
### 安全性设计
- 敏感信息脱敏:邮箱、手机号、密码哈希自动脱敏
- 软删除保护:重要数据支持软删除而非物理删除
- 并发安全内存模式支持线程安全的ID生成
### 高性能优化
- 分页查询支持limit和offset参数控制查询数量
- 索引优化:数据库模式支持索引加速查询
- 内存缓存:内存模式提供极高的查询性能
## 潜在风险
### 内存模式数据丢失
- 内存存储在应用重启后数据会丢失
- 不适用于生产环境的持久化需求
- 建议仅在开发测试环境使用
### 并发操作风险
- 内存模式的ID生成锁机制相对简单
- 高并发场景可能存在性能瓶颈
- 建议在生产环境使用数据库模式
### 数据一致性问题
- 双存储模式可能导致数据不一致
- 需要确保存储模式的正确选择和配置
- 建议在同一环境中保持存储模式一致
### 软删除数据累积
- 软删除的用户数据会持续累积
- 可能影响查询性能和存储空间
- 建议定期清理过期的软删除数据
### 唯一性约束冲突
- 用户名、邮箱等字段的唯一性约束可能导致创建失败
- 需要前端进行预检查和用户提示
- 建议提供友好的冲突解决方案
## 使用示例
```typescript
// 创建用户
const newUser = await usersService.create({
username: 'testuser',
email: 'test@example.com',
nickname: '测试用户',
password_hash: 'hashed_password'
});
// 查询用户
const user = await usersService.findByEmail('test@example.com');
// 更新用户信息
const updatedUser = await usersService.update(user.id, {
nickname: '新昵称'
});
// 搜索用户
const searchResults = await usersService.search('测试', 10);
// 批量创建用户
const batchUsers = await usersService.createBatch([
{ username: 'user1', nickname: '用户1' },
{ username: 'user2', nickname: '用户2' }
]);
```
## 模块配置
```typescript
// 数据库模式
@Module({
imports: [UsersModule.forDatabase()],
})
export class AppModule {}
// 内存模式
@Module({
imports: [UsersModule.forMemory()],
})
export class TestModule {}
```
## 版本信息
- **版本**: 1.0.1
- **主要作者**: moyin, angjustinl
- **创建时间**: 2025-12-17
- **最后修改**: 2026-01-07
- **测试覆盖**: 完整的单元测试和集成测试覆盖
## 已知问题和改进建议
### 内存服务限制
- 内存模式的 `createWithDuplicateCheck` 方法已实现,与数据库模式保持一致
- ID生成使用简单锁机制高并发场景建议使用数据库模式
### 模块配置建议
- 当前使用字符串token注入服务建议考虑使用类型安全的注入方式
- 双存储模式切换时需要确保数据一致性
