迁移到steeltoe 3.0后，steeltoe serilog动态记录器无法正常工作

如何解决迁移到steeltoe 3.0后，steeltoe serilog动态记录器无法正常工作

我在.net core 3.1应用程序中使用了steeltoe 2.4.3。最近，我将Steeltoe软件包更新为v3.0.1，看来日志不是以serilog格式出现的。我无法找出问题所在。我的应用程序设置中确实有serilog配置，如下所示。

  {
    "management": {
    "endpoints": {
      "path": "/myexample/cloudfoundryapplication","cloudfoundry": {
        "validateCertificates": false
      },"actuator": {
        "exposure": {
          "include": [ "*" ],"exclude": [ "env","refresh" ]
        }
      }
    }
  },"Serilog": {
    "MinimumLevel": {
      "Default": "Information","Override": {
        "Microsoft": "Information","Steeltoe": "Information"
      }
    },"WriteTo": [
      {
        "Name": "Console","Args": {
          "formatter": "Serilog.Formatting.Compact.CompactJsonFormatter,Serilog.Formatting.Compact"
        }
      },{
        "Name": "Trace",Serilog.Formatting.Compact"
        }
      }
    ],"Enrich": [ "FromLogContext" ]
  },"AllowedHosts": "*"
}

Program.cs如下所示

    public static class Program
    {

        public static void Main(string[] args)
        {
            Activity.DefaultIdFormat = ActivityIdFormat.W3C;
            CreateHostBuilder(args).Build().Run();
        }
       
        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .AddCloudFoundryConfiguration()
                .ConfigureLogging((builderContext,loggingBuilder) =>
                {
                    // Add Serilog Dynamic Logger 
                    loggingBuilder.AddDynamicSerilog();
                })
                .AddCloudFoundryActuators()
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }

我的.csproj在下面看起来很像。

<PropertyGroup>
   <TargetFramework>netcoreapp3.1</TargetFramework>
   <GenerateDocumentationFile>true</GenerateDocumentationFile>
 </PropertyGroup>

 <ItemGroup>
   <None Update="wwwroot\**\*;*.yml">
     <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
   </None>
 </ItemGroup>

 <ItemGroup>
   <PackageReference Include="Serilog.Sinks.Trace" Version="2.1.0" />
   <PackageReference Include="Serilog.Formatting.Compact" Version="1.1.0" />
   <PackageReference Include="Steeltoe.Extensions.Logging.DynamicSerilogCore" Version="3.0.1" />
   <PackageReference Include="Steeltoe.Management.CloudFoundryCore" Version="3.0.1" />
   <PackageReference Include="Steeltoe.Extensions.Configuration.CloudFoundryCore" Version="3.0.1" />
 </ItemGroup>

</Project>

解决方法

AddDynamicSerilog（当前）未添加控制台接收器，请尝试更新代码以使其看起来像这样：

AddDynamicSerilog(new LoggerConfiguration().WriteTo.Console())

This PR将导致如果未提供任何配置，则自动添加控制台接收器，它可能会在Steeltoe 3.0.2中提供（尚无ETA）
