📦 AsyncLoggerLib —— 高并发 SQLite 日志系统

适用于 .NET Framework 4.8 及以上版本的高并发日志记录库，使用 SQLite 存储日志，支持：

✅ 按天分库、按小时分表
✅ 自定义属性（JSON 序列化）
✅ 系统属性作为独立字段存储（线程 ID、进程 ID、设备名等）
✅ 异步/同步写入 + 缓存机制
✅ 支持配置路径和日志目录自定义
✅ 自动清理历史日志
✅ 查询服务：等级筛选、全文检索、正则匹配、排序、分页
✅ 支持 ASP.NET Core 注册为服务

🚀 快速开始

安装 NuGet 包

dotnet add package AsyncLoggerLib

🔧 使用方法

命令行 / 控制台应用示例

using AsyncLoggerLib;

class Program
{
    static void Main(string[] args)
    {
        // 初始化日志系统（自动加载 appsettings.json）
        LoggerBootstrapper.Initialize();

        // 写入日志
        Logger.Info("应用程序已启动");
        Logger.Warn("这是一个警告信息");
        Logger.Error("发生了一个错误", new Exception("测试异常"));

        Console.WriteLine("日志已写入，按任意键退出...");
        Console.ReadKey();

        // 关闭日志系统
        LoggerBootstrapper.Shutdown();
    }
}

自定义配置路径和日志目录

// 指定配置文件路径 + 日志存储目录
LoggerBootstrapper.Initialize(
    configPath: @"C:\MyApp\config\logger.json",
    logDirectory: @"D:\MyApp\logs"
);

📄 目录结构

默认日志文件会保存在程序根目录下的 Logs/ 文件夹中：

Logs/
├── 2025-04-05.db
│   ├── Logs_00
│   ├── Logs_01
│   └── ...

⚙️ 配置说明（appsettings.json）

{
  "LoggerOptions": {
    "BatchSize": 50,
    "FlushIntervalSeconds": 2,
    "MaxRetries": 3,
    "MaxDaysToKeep": 7,

    "IncludeThreadId": true,
    "IncludeProcessId": true,
    "IncludeMachineName": true,
    "IncludeProcessName": true,
    "IncludeThreadName": true
  }
}

配置项	描述
`BatchSize`	批量写入条数
`FlushIntervalSeconds`	写入间隔（秒）
`MaxRetries`	写入失败最大重试次数
`MaxDaysToKeep`	最大保留天数
`Include*`	是否记录系统属性

🔍 日志查询服务（ILogQueryService）

var queryService = new SqliteLogQueryService(dbFilePath);

var options = new LogQueryOptions
{
    LevelFilter = LogLevelFilter.Warn | LogLevelFilter.Error,
    FromTime = DateTime.Now.AddDays(-1),
    ToTime = DateTime.Now,
    FullTextSearchTerm = "error",
    OrderByTimestampDescending = true,
    PageNumber = 1,
    PageSize = 20
};

var logs = await queryService.QueryLogsAsync(options);
