-# Admin 管理员业务模块
-
-Admin 是应用的管理员业务模块，提供完整的后台管理功能，包括管理员认证、用户管理、系统监控和日志管理等核心业务能力。作为Business层模块，专注于管理员相关的业务逻辑编排和HTTP接口提供。
-
-## 管理员认证功能
-
-### login()
-管理员登录认证，支持用户名、邮箱、手机号多种标识符登录。
-
-### AdminGuard.canActivate()
-管理员权限验证守卫，确保只有role=9的管理员可以访问后台接口。
-
-## 用户管理功能
-
-### listUsers()
-分页获取用户列表，支持自定义limit和offset参数。
-
-### getUser()
-根据用户ID获取单个用户的详细信息。
-
-### resetPassword()
-管理员重置指定用户的密码，支持密码强度验证。
-
-### updateUserStatus()
-修改单个用户的账户状态，支持激活、锁定、禁用等状态变更。
-
-### batchUpdateUserStatus()
-批量修改多个用户的账户状态，提供批量操作结果统计。
-
-### getUserStatusStats()
-获取各种用户状态的数量统计信息，用于后台数据分析。
-
-## 系统监控功能
-
-### getRuntimeLogs()
-获取应用运行日志的尾部内容，支持自定义返回行数。
-
-### downloadLogsArchive()
-将整个logs目录打包为tar.gz格式并提供下载。
-
-### getLogDirAbsolutePath()
-获取日志目录的绝对路径，用于文件系统操作。
-
-## 使用的项目内部依赖
-
-### AdminCoreService (来自 core/admin_core)
-管理员认证核心服务，提供JWT Token生成、验证和密码加密等技术实现。
-
-### UsersService (来自 core/db/users)
-用户数据服务，提供用户CRUD操作的技术实现。
-
-### UsersMemoryService (来自 core/db/users)
-用户内存数据服务，提供内存模式下的用户数据操作。
-
-### LogManagementService (来自 core/utils/logger)
-日志管理服务，提供日志文件读取和管理功能。
-
-### UserStatus (来自 business/user-mgmt/enums)
-用户状态枚举，定义用户的各种状态值。
-
-### UserStatusDto (来自 business/user-mgmt/dto)
-用户状态修改数据传输对象，提供状态变更的请求结构。
-
-### BatchUserStatusDto (来自 business/user-mgmt/dto)
-批量用户状态修改数据传输对象，支持批量状态变更操作。
-
-### UserStatusResponseDto (来自 business/user-mgmt/dto)
-用户状态响应数据传输对象，定义状态操作的响应格式。
-
-### AdminLoginDto (本模块)
-管理员登录请求数据传输对象，定义登录接口的请求结构。
-
-### AdminResetPasswordDto (本模块)
-管理员重置密码请求数据传输对象，定义密码重置的请求结构。
-
-### AdminLoginResponseDto (本模块)
-管理员登录响应数据传输对象，定义登录接口的响应格式。
-
-### AdminUsersResponseDto (本模块)
-用户列表响应数据传输对象，定义用户列表接口的响应格式。
-
-### AdminUserResponseDto (本模块)
-单个用户响应数据传输对象，定义用户详情接口的响应格式。
-
-### AdminCommonResponseDto (本模块)
-通用响应数据传输对象，定义通用操作的响应格式。
-
-### AdminRuntimeLogsResponseDto (本模块)
-运行日志响应数据传输对象，定义日志接口的响应格式。
-
-## 核心特性
-
-### 完整的管理员认证体系
-- 支持多种标识符登录（用户名、邮箱、手机号）
-- JWT Token认证机制，确保接口安全性
-- 管理员权限验证，只允许role=9的用户访问
-- 登录频率限制，防止暴力破解攻击
-
-### 全面的用户管理能力
-- 用户列表分页查询，支持大数据量处理
-- 用户详情查询，提供完整的用户信息
-- 密码重置功能，支持密码强度验证
-- 用户状态管理，支持单个和批量状态修改
-- 用户状态统计，提供数据分析支持
-
-### 强大的系统监控功能
-- 实时日志查询，支持自定义行数
-- 日志文件打包下载，便于问题排查
-- 文件系统路径管理，确保操作安全性
-- 错误处理和异常监控
-
-### 业务逻辑编排优化
-- 统一的API响应格式，提供一致的接口体验
-- 完整的异常处理机制，确保系统稳定性
-- 详细的操作日志记录，便于审计和追踪
-- 私有方法提取，提高代码复用性和可维护性
-
-### 高质量的测试覆盖
-- 单元测试覆盖率100%，确保代码质量
-- 完整的异常场景测试，验证错误处理
-- Mock服务配置，实现测试隔离
-- 边界情况测试，确保系统健壮性
-
-## 潜在风险
-
-### 权限安全风险
-- 管理员Token泄露可能导致系统被恶意操作
-- 建议定期更换JWT签名密钥，设置合理的Token过期时间
-- 建议实施IP白名单限制，只允许特定IP访问管理接口
-
-### 批量操作性能风险
-- 批量用户状态修改在大数据量时可能影响性能
-- 建议设置批量操作的数量限制，避免单次处理过多数据
-- 建议实施异步处理机制，提高大批量操作的响应速度
-
-### 日志文件安全风险
-- 日志下载功能可能暴露敏感信息
-- 建议对日志内容进行脱敏处理，移除敏感数据
-- 建议实施日志访问审计，记录所有日志下载操作
-
-### 系统资源占用风险
-- 大量并发的日志查询可能影响系统性能
-- 建议实施请求频率限制，防止资源滥用
-- 建议监控系统资源使用情况，及时发现异常
-
-### 业务逻辑一致性风险
-- 用户状态修改与其他业务模块的状态同步问题
-- 建议实施事务机制，确保状态变更的原子性
-- 建议添加状态变更通知机制，保持业务数据一致性
