AutoFac学习(三)

本文主要是介绍AutoFac学习(三)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在使用AufoFac中如果一个接口有多种实现，项目中需要手动解析

IAms_assetsService _service = AutofacDependencyResolver.Current.RequestLifetimeScope.ResolveNamed<IService>("assetsService");

注册是可以使用代码如

			builder.RegisterType<Ams_assetsService>().Named<IAms_assetsService>("assetsService").PropertiesAutowired().InstancePerLifetimeScope();builder.RegisterType<ProxyAms_assetsService>().Named<IAms_assetsService>("ProxyassetsService").PropertiesAutowired().InstancePerLifetimeScope();

配置文件方法如

<?xml version="1.0" encoding="utf-8"?>
<autofac><components><component type="MyMis.Service.Ams_assetsService,MyMis.Service" service="MyMis.IService.IAms_assetsService,MyMis.IService" instance-scope="PerLifetimeScope" inject-properties="true" name="assetsService"/><component type="MyMis.Service.ProxyAms_assetsService,MyMis.Service" service="MyMis.IService.IAms_assetsService,MyMis.IService" instance-scope="PerLifetimeScope" inject-properties="true" name="ProxyassetsService"/></components>
</autofac>

不过这样解析比较麻烦，代码中需要引用using Autofac;
using Autofac.Integration.Mvc;网上看到有方法吧解析的方法独立出来，这个办法挺好

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using MyMis.Entities;
using MyMis.DTO;
using MyUtility.Interface;namespace MyMis.IService {public interface IServiceGetter:IDependency {/// <summary>/// IOC根据服务名取得服务/// </summary>/// <typeparam name="T"></typeparam>/// <param name="serviceName"></param>/// <returns></returns>T GetServiceByName<T>(string serviceName);}
}

/** IOC根据注册的名称取得对应的服务利用Autofac来实现*/
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using MyMis.IService;
using Autofac;
using Autofac.Integration.Mvc;namespace MyMis.Service.AssertManage {public class ServiceGetter:IServiceGetter {public T GetServiceByName<T>(string serviceName) {T _service = AutofacDependencyResolver.Current.RequestLifetimeScope.ResolveNamed<T>(serviceName);return _service;}}
}

使用时直接如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MyMis.IService;
using MyMis.DTO;
using MyUtility;
using Newtonsoft.Json;
using MyMis.Controllers;
using System.Threading.Tasks;
using Autofac.Integration.Mvc;
using Autofac;namespace MyMis.Web.Areas.Assets.Controllers
{public class GeneralAssetsListController : Controller{private IServiceGetter _ServiceGetter;private IAms_assetsService _service;public GeneralAssetsListController(IServiceGetter ServiceGetter,) {_ServiceGetter = ServiceGetter;_GeneralAssetsService = GeneralAssetsService;_service = _ServiceGetter.GetServiceByName<IAms_assetsService>("ProxyassetsService");}//// GET: /Assets/GeneralAssetsList/public ActionResult Index(){var r = _service.GetAssetsById("YJ19001");return View();}}
}
