ASP.NET MVC Autofac自动注入

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;
        }
    }
}
