使用 EF Core 配置 Serilog ASP.Net Core 3.2 来记录 SQL 语句

Question

以前，当使用时，Microsoft.Extensions.Logging我会注入，ILoggerFactory并且.UseLoggingFactory()在设置我的 DbContext 时，如下所示（为了简洁而减少）；

    private readonly ILoggerFactory LoggerFactory;


    public Startup(... ILoggerFactory loggerFactory)
    {
        LoggerFactory = loggerFactory ?? throw new ArgumentNullException(nameof(loggerFactory));
    }

    public void ConfigureServices(IServiceCollection services)
    {
        var connectionString = Configuration.GetConnectionString($"DbDataContext");

        services.AddDbContext<OakfieldLeasingDataContext>(
            options => options
                .UseSqlServer(
                    connectionString,
                    x => x.UseNetTopologySuite())
                .UseLoggerFactory(LoggerFactory));
     }

我现在正在尝试换入Serilog，我已成功更改Program.cs如下；

    public static void Main(string[] args)
    {
        Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Debug()
        .MinimumLevel.Override("Microsoft", LogEventLevel.Information)
        .Enrich.FromLogContext()
        .WriteTo.Console(new RenderedCompactJsonFormatter())
        .WriteTo.File(new RenderedCompactJsonFormatter(), "./logs/log.ndjson")
        .CreateLogger();

        try
        {
            Log.Information("Starting up");
            CreateHostBuilder(args).Build().Run();
        }
        catch (Exception ex)
        {
            Log.Fatal(ex, "Application start-up failed");
        }
        finally
        {
            Log.CloseAndFlush();
        }
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
        .UseSerilog() 
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        });

并可以成功确认日志正在写入日志文件。但是，使用现有代码，我收到以下错误；

System.InvalidOperationException：尝试激活“Blazor.Server.Startup”时无法解析类型“Microsoft.Extensions.Logging.ILoggerFactory”的服务。

谁能告诉我如何将 Serilog LoggerFactory 注入 EF Core 来记录 SQL 生成？

Answer 1

程序.cs

public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseSerilog()
                .MinimumLevel.Override("Microsoft.EntityFrameworkCore", Serilog.Events.LogEventLevel.Information)
                    .WriteTo.Console(restrictedToMinimumLevel: Serilog.Events.LogEventLevel.Verbose))

您需要通过以下方式包含数据库上下文：

services.AddDbContext<OakfieldLeasingDataContext>(
        options => options
            .UseSqlServer(
                connectionString,
                x => x.UseNetTopologySuite())
            .LogTo(Log.Logger.Information, LogLevel.Information, null));
