NET CORE 数据访问层服务自动注册类封装和使用源码-AutoFac
项目使用三层结构
RepositoryIocFactory
using System; using System.Reflection; using Autofac; namespace CommonHelper.AutoInject.Repository { public class RepositoryIocFactory { private static IContainer _container = null; private static object _locker = new object(); //根据命名空间自动注册类名以Repository结尾的实现类，参数是数据访问层的命名空间 public static void AutoRegisterService(string namespaceNameRegister) { if (_container != null) { return; } lock (_locker) { if (_container == null) { ContainerBuilder containerBuilder = new ContainerBuilder(); Assembly assembly = Assembly.Load(namespaceNameRegister); (from t in containerBuilder.RegisterAssemblyTypes(assembly) where t.Name.EndsWith("Repository") where !t.Name.Contains("BaseRepositorycs") select t).AsImplementedInterfaces().InstancePerDependency(); _container = containerBuilder.Build(); } } } //获取服务实例对象 public static T GetRegisterImp<T>() { T val = default(T); using ILifetimeScope context = _container.BeginLifetimeScope(); return context.Resolve<T>(); } } }
在Startup.cs类中调用AutoRegisterService方法实现注册

数据访问层实现类
/// <summary> /// 行业表 的数据访问层实现类 /// </summary> public class IndustryRepository : BaseRepository<int, IndustrySearchModel, IndustryModel>, IIndustryRepository { public override string ClassName { get { return "IndustryRepository"; } } public override string TableName { get { return "Industry"; } } }
在业务层的调用方法
/// <summary> /// 行业表 业务逻辑层接口 实现类 /// </summary> [AutoInject(typeof(IIndustryService), InjectType.Scope)] public class IndustryService : BaseService<IIndustryRepository,int, IndustrySearchModel, IndustryModel>, IIndustryService { protected override IIndustryRepository Service { //get { return RepositoryFactory.Industry; } get { return RepositoryIocFactory.GetRegisterImp<IIndustryRepository>(); } } protected override string ClassName { get { return "IndustryService"; } } }
