一、构造引擎：

1.首先Core层创建一个接口实例：

using System;using System.Collections.Generic;using System.Text;namespace General.Core{ //系统的引擎接口 public interface IEngine { /// <summary> /// 构建一个实例 /// </summary> /// <typeparam name="T"></typeparam> /// <returns></returns> T Resolve<T>() where T : class; }}

2. web层写一个继承实例的方法

using System;using System.Collections.Generic;using System.Text;namespace General.Core{ //系统的引擎接口 public interface IEngine { /// <summary> /// 构建一个实例 /// </summary> /// <typeparam name="T"></typeparam> /// <returns></returns> T Resolve<T>() where T : class; }}

3. 在core层添加该方法

using System;using System.Collections.Generic;using System.Runtime.CompilerServices;using System.Runtime;using System.Text;namespace General.Core{ public class EnginContext { private static IEngine _engine; /// <summary> /// 静态方法的形式去构造出一个对象 /// </summary> /// <param name="engine"></param> /// <returns></returns> /// 该方法就是保证每次只有一个 [MethodImpl(MethodImplOptions.Synchronized)] public static IEngine Initialize(IEngine engine) { if (_engine == null) _engine = engine; return _engine; } /// <summary> /// 当前引擎 /// </summary> public static IEngine Current { get { return _engine; } } }}

4. 添加一个业务层操作对象

 // 添加对象 EnginContext.Initialize(new GeneralEngine(services.BuildServiceProvider()));
