c# autofac结合WebApi的使用
一、下载相关类库引用
install-package Autofac
install-package Autofac.Mvc4
install-package Autofac.WebApi2
二、配置autofac
public class AutofacUtil { ////// Autofac容器对象 /// private static IContainer _container; /// /// 初始化autofac /// public static void InitAutofac() { var builder = new ContainerBuilder(); builder.RegisterControllers(Assembly.GetCallingAssembly()); builder.RegisterApiControllers(Assembly.GetCallingAssembly()); //配置接口依赖 builder.RegisterInstance (DBFactory.CreateConnection()).As (); builder.RegisterGeneric(typeof(GenericRepository<>)).As(typeof(IGenericRepository<>)); //注入仓储类 builder.RegisterAssemblyTypes(Assembly.Load("Demo.Repository")) .Where(x => x.Name.EndsWith("Repository")) .AsImplementedInterfaces(); _container = builder.Build(); //设置MVC依赖注入 DependencyResolver.SetResolver(new AutofacDependencyResolver(_container)); //设置WebApi依赖注入 GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver((IContainer)_container); } /// /// 从Autofac容器获取对象 /// /// /// public static T GetFromFac () { return _container.Resolve (); } }
三、注册autofac
在Global.asax全局文件中Application_Start方法添加代码
AutofacUtil.InitAutofac();
四、使用案例
public class CodeController : BaseApiController { private readonly ISMCodeRepository _smCodeRepository; public CodeController(ISMCodeRepository smCodeRepository) { _smCodeRepository = smCodeRepository; } ////// 获取数据字典数据列表 /// /// 数据字典字典类型代码 /// [HttpPost] public ApiResult GetCodeList(SMCodeType codeTypeEntity) { var result = _smCodeRepository.GetCodeList(codeTypeEntity.CodeTypeNo); return new ApiResult() { Data = result.Select(x => new { x.CodeNo, x.CodeName }) }; } }
