Aore.Logger.SQLite — SQLite 日志扩展包

Aore.Logger 的 SQLite 数据库日志目标：零部署、单文件即库，适合单机应用、嵌入式场景与集成测试。

1. 作用与目的

把日志同步写入 SQLite 数据库表，支持：

  • 自动建表/建索引：目标构造时自动 CREATE TABLE IF NOT EXISTS + 时间戳/级别两个索引，无需手工 DDL；
  • 结构探测 fail-fast：表已存在但缺少已映射列时构造期抛错（不会静默丢日志）；
  • 字段映射：9 个字段（含 UTC 时间列）的列名逐字段可配、可置 null 跳过，支持写入现有表；
  • 保留清理：可选按天保留，后台分批删除（每批 5000 行），不阻塞写入；
  • 参数化写入：消息/异常全部经驱动参数绑定，无 SQL 注入面。

2. 安装与依赖

dotnet add package Aore.Logger.SQLite
  • 依赖驱动：Microsoft.Data.Sqlite 8.0.29（自动引入）
  • 必须同时引用核心包 Aore.Logger
  • 目标框架：netstandard2.0 / net462 / net472 / net48 / net8.0

3. 快速上手

using Aore.Logger;

Logger.Instance.Configure(new LoggerConfig
{
    EnableFileLog = false,               // 也可 true 双写
    EnableDatabaseLog = true,
    DatabaseLogConfig = new DatabaseLogConfig
    {
        DatabaseType = DatabaseType.SQLite,
        ConnectionString = "Data Source=D:/logs/app.db",   // 建议绝对路径
        TableName = "Logs"
    }
});

Logger.Instance.Info("写入 SQLite 的日志");

连接失败/建表失败在 Configure 时抛出（保留旧目标列表并带内层异常），不会等到写日志才发现。

4. 自动创建的表与索引

CREATE TABLE IF NOT EXISTS "Logs" (
    "Id" TEXT PRIMARY KEY NOT NULL,           -- Guid 字符串（36 位）
    "Timestamp" TEXT NOT NULL,                -- 'yyyy-MM-dd HH:mm:ss.fff' 文本，毫秒保留
    "Level" TEXT NOT NULL,                    -- 'INFO'/'ERROR'/...
    "Message" TEXT NOT NULL,
    "Exception" TEXT,
    "MemberName" TEXT,
    "FilePath" TEXT,
    "LineNumber" INTEGER,
    "createdGMT" TEXT NOT NULL                -- UTC 时间（Timestamp 转换）
);
-- 另按已映射列创建 Timestamp 与 Level 两个索引

5. 连接字符串

  • 常规：Data Source=app.db
  • 相对路径基于进程当前工作目录（不是程序目录），生产环境建议绝对路径；
  • Data Source=:memory: 可用于集成测试——注意内存库生命周期与连接绑定，且每条日志独立借还连接，需配合驱动池化语义理解其局限（建议 ;Pooling=False 时明确知晓每条日志拿到的是不同内存库）。

6. 清理（保留策略）

IsClearingExecuted = true 启用：写入时命中周期窗口（小时数 % ExecuteClearingCycle == 0）派发后台清理，按已映射的时间戳列删除早于 RetentionDays 的行，按 rowid 分批（5000 行/批）循环删除——不依赖 Id 列，自增主键现有表（IdColumn = null）清理照常工作。

7. 写入现有表（字段映射）

把列名置 null 表示不写该字段，映射到现有列名即写入现有表：

DatabaseLogConfig = new DatabaseLogConfig
{
    DatabaseType = DatabaseType.SQLite,
    ConnectionString = "Data Source=app.db",
    TableName = "sys_oper_log",
    IdColumn = null,                      // 自增主键表必须置 null
    TimestampColumn = "created_at",
    LevelColumn = "log_level",
    MessageColumn = "content",
    MemberNameColumn = null               // 无此列，跳过
}

完整规则（三态语义、校验、类型兼容矩阵）见 数据库日志通用手册。

8. 本方言注意事项

  1. 时间戳为固定格式文本（yyyy-MM-dd HH:mm:ss.fff）：字符串比较即为时间序，但按时间范围查询需用同格式字面量或 datetime() 函数；
  2. 标识符以双引号转义，表名/列名仅允许 字母/数字/下划线/$（违规构造期抛 InvalidOperationException）；
  3. 排障可用 new SQLiteLogTarget(config).TestConnection() 探测连通性；
  4. SQLite 单写者模型：多进程同时写同一库文件可能遇到 database is locked（该条被 Logger 吞掉）。高频并发写建议改用客户端/服务端数据库（MySQL/PostgreSQL）。
