Autofac构建
2024-08-26 09:38:22
1.初始化
using System.Reflection;
using System.Web;
using System.Web.Mvc;
using System.Configuration;
using System;
using System.IO;
using Autofac;
using Autofac.Core;
using Autofac.Integration.Mvc; public static IContainer RegisterIOC()
{
ContainerBuilder builder = new ContainerBuilder();
//构造函数注入
builder.RegisterAssemblyTypes(Assembly.GetCallingAssembly()).AsImplementedInterfaces();
//注入控制器并实现属性注入
builder.RegisterControllers(Assembly.GetCallingAssembly()).PropertiesAutowired();
//支持过滤器的属性注入
builder.RegisterFilterProvider(); builder.RegisterType<AccountService>().As<IAccountService>(); var container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container)); return container;
}
2.在global.asax.cs
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas(); WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles); Func<ILifetimeScope, ILifetimeScope> scopeProvider = (ILifetimeScope container) =>
{
if (HttpContext.Current.Items[typeof(ILifetimeScope)] == null)
{
HttpContext.Current.Items[typeof(ILifetimeScope)] = container.BeginLifetimeScope("AutofacWebRequest");
} return (ILifetimeScope)HttpContext.Current.Items[typeof(ILifetimeScope)];
}; scopeProvider (RegisterIOC())
}
3.手工获取
public class BeanFactory
{
/// <summary>
/// 获取Bean
/// </summary>
/// <typeparam name="T">获取的实例类型</typeparam>
/// <returns>获取的实例</returns>
public static T GetBean<T>()
{
try
{
if (System.Web.HttpContext.Current != null)
{
ILifetimeScope scope = System.Web.HttpContext.Current.Items[typeof(ILifetimeScope)] as ILifetimeScope;
if (scope != null)
{
return scope.Resolve<T>();
}
}
}
catch
{
} return ServiceLocator.Current.GetInstance<T>();
} /// <summary>
/// 获取Bean
/// </summary>
/// <param name="type"></param>
/// <returns></returns>
public static object GetBean(System.Type type)
{
try
{
if (System.Web.HttpContext.Current != null)
{
ILifetimeScope scope = System.Web.HttpContext.Current.Items[typeof(ILifetimeScope)] as ILifetimeScope;
if (scope != null)
{
return scope.Resolve(type);
}
}
}
catch
{
} return ServiceLocator.Current.GetInstance (type) ;
}
}
