### 🏷️ ORM 属性标记 (GameFrameX.Foundation.Orm.Attribute)
提供ORM框架的属性标记,用于标识实体类的特殊功能,如审计跟踪、缓存策略、软删除和版本控制等。
#### 核心组件概览
| 组件 | 文件名 | 主要功能 |
|--------------|------------------------|-----------------------------------------|
| **审计表属性** | `AuditTableAttribute.cs` | 标记实体类支持审计跟踪功能,记录数据变更历史 |
| **缓存表属性** | `CacheTableAttribute.cs` | 标记实体类支持缓存策略,提升数据访问性能 |
| **软删除属性** | `SoftDeleteAttribute.cs` | 标记实体类支持软删除功能,逻辑删除而非物理删除 |
| **版本控制属性** | `VersionControlAttribute.cs` | 标记实体类支持数据版本管理,实现乐观锁和并发控制 |
#### 审计表属性 (AuditTableAttribute)
用于标记需要进行审计跟踪的实体类,系统会自动记录数据的创建、修改、删除等操作历史。
```csharp
using GameFrameX.Foundation.Orm.Attribute;
using GameFrameX.Foundation.Orm.Entity;
// 标记用户表需要审计跟踪
[AuditTable]
public class User : EntityBase
{
public string Username { get; set; }
public string Email { get; set; }
public string PasswordHash { get; set; }
// EntityBase已包含审计字段:
// CreateTime, UpdateTime, CreateUserId, UpdateUserId,
// CreateUserName, UpdateUserName
}
// 标记订单表需要审计跟踪
[AuditTable]
public class Order : EntityBase
{
public string OrderNumber { get; set; }
public long UserId { get; set; }
public decimal TotalAmount { get; set; }
public DateTime OrderDate { get; set; }
}
// 审计拦截器示例
public class AuditInterceptor : IDbCommandInterceptor
{
private readonly ICurrentUserService _currentUserService;
public AuditInterceptor(ICurrentUserService currentUserService)
{
_currentUserService = currentUserService;
}
public override InterceptionResult<int> NonQueryExecuting(
DbCommand command,
CommandEventData eventData,
InterceptionResult<int> result)
{
var context = eventData.Context;
var entries = context.ChangeTracker.Entries()
.Where(e => e.Entity.GetType().GetCustomAttribute<AuditTableAttribute>() != null)
.ToList();
foreach (var entry in entries)
{
if (entry.Entity is IAuditableEntity auditableEntity)
{
var currentUser = _currentUserService.GetCurrentUser();
var now = DateTime.UtcNow;
switch (entry.State)
{
case EntityState.Added:
auditableEntity.CreateTime = now;
auditableEntity.UpdateTime = now;
auditableEntity.CreateUserId = currentUser.Id;
auditableEntity.UpdateUserId = currentUser.Id;
auditableEntity.CreateUserName = currentUser.Username;
auditableEntity.UpdateUserName = currentUser.Username;
break;
case EntityState.Modified:
auditableEntity.UpdateTime = now;
auditableEntity.UpdateUserId = currentUser.Id;
auditableEntity.UpdateUserName = currentUser.Username;
break;
}
}
}
return base.NonQueryExecuting(command, eventData, result);
}
}
用于标记支持缓存策略的实体类,系统会自动对这些表的数据进行缓存管理。
using GameFrameX.Foundation.Orm.Attribute;
using GameFrameX.Foundation.Orm.Entity;
// 标记配置表支持缓存(配置数据变化频率低,适合缓存)
[CacheTable]
public class SystemConfig : EntityBase
{
public string ConfigKey { get; set; }
public string ConfigValue { get; set; }
public string Description { get; set; }
public string Category { get; set; }
}
// 标记字典表支持缓存(字典数据相对稳定,适合缓存)
[CacheTable]
public class Dictionary : EntityBase
{
public string DictType { get; set; }
public string DictKey { get; set; }
public string DictValue { get; set; }
public string Description { get; set; }
public int SortOrder { get; set; }
}
// 标记权限表支持缓存(权限数据访问频繁但变化不频繁)
[CacheTable]
public class Permission : EntityBase
{
public string PermissionCode { get; set; }
public string PermissionName { get; set; }
public string Description { get; set; }
public string Module { get; set; }
}
// 缓存服务示例
public class CacheService<T> where T : class
{
private readonly IMemoryCache _memoryCache;
private readonly IDbContext _dbContext;
private readonly ILogger<CacheService<T>> _logger;
public CacheService(IMemoryCache memoryCache, IDbContext dbContext, ILogger<CacheService<T>> logger)
{
_memoryCache = memoryCache;
_dbContext = dbContext;
_logger = logger;
}
public async Task<List<T>> GetAllAsync()
{
var entityType = typeof(T);
var cacheAttribute = entityType.GetCustomAttribute<CacheTableAttribute>();
if (cacheAttribute == null)
{
// 不支持缓存,直接从数据库查询
return await _dbContext.Set<T>().ToListAsync();
}
var cacheKey = $"CacheTable_{entityType.Name}_All";
if (_memoryCache.TryGetValue(cacheKey, out List<T> cachedData))
{
_logger.LogDebug($"从缓存获取数据: {cacheKey}");

除了 OptionsBuilder 之外,您也可以直接使用底层的 CommandLineArgumentConverter:
using GameFrameX.Foundation.Options;
// 创建转换器实例
var converter = new CommandLineArgumentConverter();
// 原始命令行参数
var args = new[] { "--port", "8080", "-h", "localhost" };
// 设置环境变量(可选)
Environment.SetEnvironmentVariable("APP_NAME", "MyApplication");
Environment.SetEnvironmentVariable("LOG_LEVEL", "debug-mode");
// 转换为标准格式(合并命令行参数和环境变量)
var standardArgs = converter.ConvertToStandardFormat(args);
// 结果: ["--port", "8080", "-h", "localhost", "--APP_NAME", "MyApplication", "--LOG_LEVEL", "debugmode"]
// 转换为命令行字符串
var commandLineString = converter.ToCommandLineString(standardArgs);
// 结果: "--port 8080 -h localhost --APP_NAME MyApplication --LOG_LEVEL debugmode"
// 获取所有环境变量
var envVars = converter.GetEnvironmentVariables();
Console.WriteLine($"检测到 {envVars.Count} 个环境变量");
CommandLineArgumentConverter 支持智能识别和处理布尔类型参数,提供三种格式:
using GameFrameX.Foundation.Options;
// 设置布尔类型环境变量
Environment.SetEnvironmentVariable("ENABLE_LOGGING", "true");
Environment.SetEnvironmentVariable("DEBUG_MODE", "false");
Environment.SetEnvironmentVariable("VERBOSE", "yes");
var converter = new CommandLineArgumentConverter();
// 1. 标志格式 (默认) - 只为 true 值添加标志
converter.BoolFormat = BoolArgumentFormat.Flag;
var flagArgs = converter.ConvertToStandardFormat(Array.Empty<string>());
// 结果: ["--ENABLE_LOGGING", "--VERBOSE"] (只包含 true 值)
// 2. 键值对格式 - 添加键值对
converter.BoolFormat = BoolArgumentFormat.KeyValue;
var keyValueArgs = converter.ConvertToStandardFormat(Array.Empty<string>());
// 结果: ["--ENABLE_LOGGING", "true", "--DEBUG_MODE", "false", "--VERBOSE", "true"]
// 3. 分离格式 - 键和值分开
converter.BoolFormat = BoolArgumentFormat.Separated;
var separatedArgs = converter.ConvertToStandardFormat(Array.Empty<string>());
// 结果: ["--ENABLE_LOGGING", "true", "--DEBUG_MODE", "false", "--VERBOSE", "true"]
支持的布尔值格式:
"true", "1", "yes", "on", "enabled" (不区分大小写)"false", "0", "no", "off", "disabled" (不区分大小写)提供一系列实用的工具类,包含控制台操作、环境管理、时间处理和雪花ID生成等功能。

雪花ID(Snowflake)是Twitter开源的分布式ID生成算法,具有以下特点:
ID结构(64位):
0 - 0000000000 0000000000 0000000000 0000000000 0 - 00000 - 00000 - 000000000000 | | | | | | | |<-------------- 41位时间戳 ---------------->| |<-5位->|<-5位->|<--12位--> | | | | 符号位(1位) | 数据中心ID 序列号 | (5位) (12位) 工作节点ID (5位)
