AspectCore使用 属性注入FromServiceContext

.net5.0

nuget

1 2 3

<PackageReference Include="AspectCore.Core" Version="2.1.0" /> <PackageReference Include="AspectCore.Extensions.DependencyInjection" Version="2.1.0" /> <PackageReference Include="AspectCore.Extensions.Hosting" Version="2.1.0" />

　　

配置：

1 2 3 4

public static void Main(string[] args) {     CreateHostBuilder(args).UseServiceContext().Build().Run(); }

StartUp

1	services.AddControllersWithViews().AddControllersAsServices();

　注意AddControllersAsServices方法，不添加则Controller中属性注入不生效！！！　

==============================注意：属性注入，字段不行==============================

 

[AspectCore.DependencyInjection.FromServiceContext]
private ILogger<PrintController> log { get; set; }

 

 

构造完成才会注入
