-# 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

+/**
+ * 位置广播WebSocket网关
+ * 
+ * 功能描述：
+ * - 处理WebSocket连接和断开事件
+ * - 管理用户会话的加入和离开
+ * - 实时广播用户位置更新
+ * - 提供心跳检测和连接状态管理
+ * 
+ * 职责分离：
+ * - WebSocket连接管理：处理连接建立、断开和错误
+ * - 消息路由：根据消息类型分发到对应的处理器
+ * - 认证集成：使用JWT认证守卫保护WebSocket事件
+ * - 实时广播：向会话中的其他用户广播位置更新
+ * 
+ * 技术实现：
+ * - Socket.IO：提供WebSocket通信能力
+ * - JWT认证：保护需要认证的WebSocket事件
+ * - 核心服务集成：调用位置广播核心服务处理业务逻辑
+ * - 异常处理：统一的WebSocket异常处理和错误响应
+ * 
+ * 最近修改：
+ * - 2026-01-08: 代码重构 - 提取魔法数字为常量，优化代码质量 (修改者: moyin)

+/**
+ * 性能监控中间件
+ * 
+ * 功能描述：
+ * - 监控WebSocket事件处理的性能指标
+ * - 收集响应时间、吞吐量等关键数据
+ * - 提供实时性能统计和报告
+ * - 支持性能预警和异常检测
+ * 
+ * 职责分离：
+ * - 性能收集：记录事件处理的时间和资源消耗
+ * - 数据分析：计算平均值、百分位数等统计指标
+ * - 监控报警：检测性能异常和瓶颈
+ * - 报告生成：提供详细的性能分析报告
+ * 
+ * 技术实现：
+ * - 高精度计时：使用process.hrtime进行精确测量
+ * - 内存优化：循环缓冲区存储历史数据
+ * - 异步处理：不影响正常业务流程
+ * - 统计算法：实时计算各种性能指标
+ * 
+ * 最近修改：
+ * - 2026-01-08: 代码重构 - 提取魔法数字为常量，优化代码质量 (修改者: moyin)
+ * 
+ * @author moyin
+ * @version 1.1.0

+ * 功能描述：
+ * - 限制用户位置更新的频率，防止过度请求
+ * - 基于用户ID和时间窗口的限流算法
+ * - 支持动态配置和监控统计
+ * - 提供优雅的限流响应和错误处理
+ * 
+ * 职责分离：
+ * - 频率控制：实现基于时间窗口的请求限制
+ * - 用户隔离：每个用户独立的限流计数
+ * - 配置管理：支持动态调整限流参数
+ * - 监控统计：记录限流事件和性能指标
+ * 
+ * 技术实现：
+ * - 滑动窗口算法：精确控制请求频率
+ * - 内存缓存：高性能的计数器存储
+ * - 异步处理：不阻塞正常请求流程
+ * - 错误恢复：处理异常情况的降级策略

+/**
+ * 自动清理服务
+ * 
+ * 功能描述：
+ * - 定期清理过期的会话数据
+ * - 清理断开连接用户的位置信息
+ * - 清理过期的缓存数据
+ * - 优化Redis内存使用
+ * 
+ * 职责分离：
+ * - 数据清理：清理过期和无效数据
+ * - 内存优化：释放不再使用的内存
+ * - 定时任务：按计划执行清理操作
+ * - 监控报告：记录清理操作的统计信息
+ * 
+ * 技术实现：
+ * - 定时器：使用setInterval执行定期清理
+ * - 批量操作：批量删除数据提高效率
+ * - 异常处理：确保清理失败不影响系统
+ * - 统计记录：记录清理操作的详细信息
+ * 
+ * 最近修改：
+ * - 2026-01-08: 代码重构 - 提取魔法数字为常量，优化代码质量 (修改者: moyin)
+ *

+
+## 使用示例
+
+### 基本使用
+
+```typescript
+// 在业务模块中导入
+@Module({
+  imports: [
+    UserProfilesModule.forDatabase(), // 生产环境
+    // 或 UserProfilesModule.forMemory(), // 测试环境
+  ],
+})
+export class BusinessModule {}
+
+// 在服务中注入使用
+@Injectable()
+export class SomeBusinessService {
+  constructor(
+    @Inject('IUserProfilesService')
+    private readonly userProfiles: UserProfilesService,
+  ) {}
+
+  async getUserLocation(userId: bigint) {
+    const profile = await this.userProfiles.findByUserId(userId);
+    return profile ? {
+      map: profile.current_map,
+      x: profile.pos_x,
+      y: profile.pos_y
+    } : null;
+  }
+}
+```
+
+### 位置更新示例
+
+```typescript
+// 更新用户位置
+await userProfilesService.updatePosition(
+  BigInt(123),
+  {
+    current_map: 'forest',
+    pos_x: 150.5,
+    pos_y: 200.3
+  }
+);
+
+// 查询地图用户
+const onlineUsers = await userProfilesService.findByMap(
+  'plaza', 
+  1, // 在线状态
+  20, // 限制20个
+  0   // 偏移量0
+);
+```

+   * 更新用户位置信息
+   *

+   * 
+   * 技术实现：
+   * 1. 根据用户ID查找档案记录
+   * 2. 更新位置相关字段（地图、坐标）
+   * 3. 自动更新位置更新时间戳
+   * 4. 执行数据库更新操作
+   * 5. 记录位置更新日志
+   * 
+   * 性能优化：
+   * - 只更新位置相关字段，减少数据传输
+   * - 使用部分更新，避免全量数据操作
+   * - 批量操作支持，提高并发性能
+   * 
+   * @param userId 用户ID
+   * @param positionData 位置数据
+   * @returns 更新后的用户档案实体
+   * @throws NotFoundException 当用户档案不存在时

+   * ```typescript
+   * // 更新用户位置
+   * const updatedProfile = await userProfilesService.updatePosition(

+/**
+ * 用户档案内存服务类
+ * 
+ * 功能描述：
+ * - 提供用户档案数据的内存存储实现
+ * - 使用Map数据结构进行高性能数据管理
+ * - 支持完整的CRUD操作和位置信息管理
+ * - 为开发测试环境提供零依赖的数据存储方案
+ * 
+ * 职责分离：
+ * - 数据存储：使用Map进行内存数据管理
+ * - ID生成：线程安全的自增ID生成机制
+ * - 数据验证：数据完整性和唯一性约束检查
+ * - 性能监控：操作耗时统计和日志记录
+ * 
+ * 技术特点：
+ * - 高性能：直接内存访问，无IO开销
+ * - 零依赖：无需数据库连接，快速启动
+ * - 完整功能：实现与数据库服务相同的接口
+ * - 易测试：便于单元测试和集成测试
+ * 
+ * 使用场景：
+ * - 开发环境快速启动和调试
+ * - 单元测试和集成测试
+ * - 演示和原型开发
+ * - 数据库故障时的降级方案
+ * 
+ * 最近修改：
+ * - 2026-01-08: 功能新增 - 创建用户档案内存服务，支持位置广播系统 (修改者: moyin)
+ * 
+ * @author moyin
+ * @version 1.0.0
+ * @since 2026-01-08
