Aore.Logger.SqlServer — SQL Server 日志扩展包

Aore.Logger 的 SQL Server 数据库日志目标：Windows 生态首选，NVARCHAR 中文安全、DATETIME2 强类型时间。

1. 作用与目的

把日志同步写入 SQL Server 数据库表，支持：

  • 自动建表/建索引：构造时自动建表（[方括号] 转义标识符）+ 时间戳/级别索引；
  • 强类型时间：DATETIME2(3) 列 + SqlDbType.DateTime2 参数，毫秒精度、无字符串转换；
  • Unicode 安全：文本列统一 NVARCHAR（N 前缀参数），中文消息不乱码；
  • 字段映射：9 个字段列名逐字段可配、可置 null 跳过，支持写入现有表；
  • 保留清理：可选按天保留，后台 DELETE TOP (5000) 分批删除，不阻塞写入。

2. 安装与依赖

dotnet add package Aore.Logger.SqlServer
  • 依赖驱动：Microsoft.Data.SqlClient 6.1.6（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,
    EnableDatabaseLog = true,
    DatabaseLogConfig = new DatabaseLogConfig
    {
        DatabaseType = DatabaseType.SqlServer,
        ConnectionString = "Server=192.168.1.20;Database=applogs;User Id=loguser;Password=******;TrustServerCertificate=true",
        TableName = "Logs"
    }
});

Logger.Instance.Info("写入 SQL Server 的日志");

Windows 集成认证：Server=.;Database=applogs;Trusted_Connection=True;。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）。

Microsoft.Data.SqlClient 4.0+ 默认 Encrypt=True，自签名证书环境需加 TrustServerCertificate=true，否则构造期即报证书信任错误。

4. 自动创建的表与索引

CREATE TABLE [Logs] (
    [Id] UNIQUEIDENTIFIER NOT NULL PRIMARY KEY,   -- Guid
    [Timestamp] DATETIME2(3) NOT NULL,            -- 毫秒精度，强类型参数
    [Level] NVARCHAR(50) NOT NULL,
    [Message] NVARCHAR(MAX) NOT NULL,
    [Exception] NVARCHAR(MAX),
    [MemberName] NVARCHAR(500),
    [FilePath] NVARCHAR(1000),
    [LineNumber] INT,
    [createdGMT] DATETIME2(3) NOT NULL            -- UTC 时间（Timestamp 转换）
);
-- 另按已映射列创建 Timestamp 与 Level 两个索引

5. 清理（保留策略）

IsClearingExecuted = true 启用：写入时命中周期窗口派发后台清理，按已映射的时间戳列删除早于 RetentionDays 的行；DELETE TOP (5000) 循环删到无行可删——短事务、不依赖 Id 列（IDENTITY 自增表 IdColumn = null 清理照常）。

6. 写入现有表（字段映射）

DatabaseLogConfig = new DatabaseLogConfig
{
    DatabaseType = DatabaseType.SqlServer,
    ConnectionString = "...",
    TableName = "sys_oper_log",
    IdColumn = null,                      -- IDENTITY(1,1) 表必须置 null！
    TimestampColumn = "created_at",
    LevelColumn = "log_level",
    MessageColumn = "content"
}

⚠️ IDENTITY(1,1) 列必须 IdColumn = null（未开 IDENTITY_INSERT 时显式写自增列直接报错，每条写入失败且被 Logger 吞掉）。

7. 本方言注意事项

  1. 索引名上限 128 字符：超长自动截断 + FNV-1a 哈希后缀；
  2. 标识符以 [方括号] 转义，表名/列名仅允许 字母/数字/下划线/$；
  3. default(DateTime)（0001-01-01）超出 DATETIME2 语义范围，Timestamp 请使用正常业务时间；
  4. 排障可用 new SqlServerLogTarget(config).TestConnection() 探测连通性；
  5. 连接串支持 Maximum Pool Size（默认池化开启），高频写日志场景可适当调大。
