用SimpleInjector在IExceptionFilter中注入记录器

using Microsoft.AspNetCore.Mvc.Filters;
using Microsoft.Extensions.Logging;

public class CustomExceptionFilterAttribute : IExceptionFilter
{
    private readonly ILogger _logger;

    public CustomExceptionFilterAttribute(ILogger<CustomExceptionFilterAttribute> logger)
    {
        _logger = logger;
    }

    public void OnException(ExceptionContext context)
    {
        // 处理异常并记录异常信息
        _logger.LogError(context.Exception, "An exception occurred.");
    }
}

using Microsoft.Extensions.DependencyInjection;
using SimpleInjector;
using SimpleInjector.Integration.AspNetCore.Mvc;
using SimpleInjector.Lifestyles;

public void ConfigureServices(IServiceCollection services)
{
    // 创建SimpleInjector容器
    var container = new Container();
    container.Options.DefaultScopedLifestyle = new AsyncScopedLifestyle();

    // 注册ILogger
    container.Register<ILogger>(() => new LoggerFactory().CreateLogger("Logger"), Lifestyle.Scoped);

    // 注册CustomExceptionFilterAttribute
    container.Register<CustomExceptionFilterAttribute>(Lifestyle.Scoped);

    // 将SimpleInjector容器包装为IServiceProvider
    services.AddSingleton<IServiceProviderFactory<Container>>(new SimpleInjectorServiceProviderFactory(container));

    // 添加MVC服务并将控制器注册到SimpleInjector容器
    services.AddMvc().AddControllersAsServices();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // ...

    // 使用SimpleInjector作为默认的依赖注入容器
    app.UseSimpleInjector(app.ApplicationServices.GetRequiredService<IServiceProviderFactory<Container>>());

    // ...
}
