依赖注入容器有很多插件,我用过Unity和Autofac,这两个插件给我最明显的感觉就是Autofac很快,非常的快,毕竟是第三方开发的,而Unity相对而言性能比较稳定
下面附上Autofac自动注入代码:(IDependency接口表示要注入的接口必须要继承它,WEB中必须要添加接口类库和接口实现类库,否则会注入失败),其实原理就是反射
using System.Linq; using System.Reflection; using System.Web.Compilation; using System.Web.Mvc; using Autofac; using Autofac.Integration.Mvc; using Framework.Core; namespace MsSystem.Web { /// <summary> /// Autofac依赖注入配置 /// </summary> public class AutofacConfig { /// <summary> /// 初始化 /// </summary> public static void Initialise() { var builder = RegisterService(); DependencyResolver.SetResolver(new AutofacDependencyResolver(builder.Build())); } /// <summary> /// 注入实现 /// </summary> /// <returns></returns> private static ContainerBuilder RegisterService() { var builder = new ContainerBuilder(); var baseType = typeof(IDependency); //扫描IService和Service相关的程序集 var assemblys = BuildManager.GetReferencedAssemblies().Cast<Assembly>() .Where(m => m.FullName.Contains("MsGPM")).ToList(); builder.RegisterControllers(assemblys.ToArray()); //自动注入 builder.RegisterAssemblyTypes(assemblys.ToArray()) .Where(t => baseType.IsAssignableFrom(t) && t != baseType) .AsImplementedInterfaces().InstancePerLifetimeScope(); return builder; } } }
在Global Application_Start 中添加AutofacConfig.Initialise()方法即可。
使用的话,我一般都是构造函数注入方式
