我想在ASP.NET CORE 1中实现依赖注入.我知道一切都是关于.Net Core中的DI.例如
public void ConfigureServices(IServiceCollection services)
{
// Add application services.
services.AddTransient<IDateTime,SystemDateTime>();
}
但是对于拥有20多个实体和服务的大型项目来说,写入ConfigurationServices中的所有代码行是非常困难和不可读的.我想知道这是否可能在Startup.cs之外执行依赖注入,然后将其添加到服务中.
感谢您的答案.
解决方法
您可以编写IServiceCollection的扩展方法,将许多服务注册封装到Startup.cs中的一行代码中
例如这里有一个来自我的项目：
using cloudscribe.Core.Models;
using cloudscribe.Core.Models.Setup;
using cloudscribe.Core.Web;
using cloudscribe.Core.Web.Components;
using cloudscribe.Core.Web.Components.Editor;
using cloudscribe.Core.Web.Components.Messaging;
using cloudscribe.Core.Web.Navigation;
using cloudscribe.Web.Common.Razor;
using cloudscribe.Web.Navigation;
using cloudscribe.Web.Navigation.Caching;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc.Razor;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection.Extensions;
using Microsoft.Extensions.FileProviders;
using Microsoft.Extensions.Options;
using System.Reflection;
using Microsoft.AspNetCore.Authorization;
namespace Microsoft.Extensions.DependencyInjection
{
public static class StartupExtensions
{
public static IServiceCollection AddCloudscribeCore(this IServiceCollection services,IConfigurationRoot configuration)
{
services.TryAddSingleton<IHttpContextAccessor,HttpContextAccessor>();
services.Configure<MultiTenantOptions>(configuration.GetSection("MultiTenantOptions"));
services.Configure<SiteConfigOptions>(configuration.GetSection("SiteConfigOptions"));
services.Configure<UIOptions>(configuration.GetSection("UIOptions"));
services.Configure<CkeditorOptions>(configuration.GetSection("CkeditorOptions"));
services.Configure<CachingSiteResolverOptions>(configuration.GetSection("CachingSiteResolverOptions"));
services.AddMultitenancy<SiteContext,CachingSiteResolver>();
services.AddScoped<CacheHelper,CacheHelper>();
services.AddScoped<SiteManager,SiteManager>();
services.AddScoped<GeoDataManager,GeoDataManager>();
services.AddScoped<SystemInfoManager,SystemInfoManager>();
services.AddScoped<IpAddressTracker,IpAddressTracker>();
services.AddScoped<SiteDataProtector>();
services.AddCloudscribeCommmon();
services.AddScoped<ITimeZoneIdResolver,RequestTimeZoneIdResolver>();
services.AddCloudscribePagination();
services.AddScoped<IVersionProviderFactory,VersionProviderFactory>();
services.AddScoped<IVersionProvider,CloudscribeCoreVersionProvider>();
services.AddTransient<ISiteMessageEmailSender,SiteEmailMessageSender>();
services.AddTransient<ISmsSender,SiteSmsSender>();
services.AddSingleton<IThemeListBuilder,SiteThemeListBuilder>();
services.TryAddScoped<ViewRenderer,ViewRenderer>();
services.AddSingleton<IOptions<NavigationOptions>,SiteNavigationOptionsResolver>();
services.AddScoped<ITreeCacheKeyResolver,SiteNavigationCacheKeyResolver>();
services.AddScoped<INodeUrlPrefixProvider,FolderTenantNodeUrlPrefixProvider>();
services.AddCloudscribeNavigation(configuration);
services.AddCloudscribeIdentity();
return services;
}
}
}
services.AddCloudscribeCore(Configuration);
