结合设计模式,通过代码理解面向切面编程，有代码的很好理解的，5分钟可以看三遍
通过,结构型设计模式，装饰器模式来实现AOP，代码如下
/// <summary> /// 装饰器模式实现静态代理 /// AOP 在方法前后增加自定义的方法 /// </summary> public class DecoratorAOP { public static void Show() { User user = new User() { Name = "Eleven", Password = "123123123123" }; //直接调用 IUserProcessor processor = new UserProcessor(); processor.RegUser(user); Console.WriteLine("***************"); //通过装饰器模式,在方法执行前后添加功能 processor = new UserProcessorDecorator(processor); processor.RegUser(user); } public interface IUserProcessor { void RegUser(User user); } public class UserProcessor : IUserProcessor { public void RegUser(User user) { Console.WriteLine("用户已注册。Name:{0},PassWord:{1}", user.Name, user.Password); } } /// <summary> /// 装饰器的模式去提供一个AOP功能 /// </summary> public class UserProcessorDecorator : IUserProcessor { private IUserProcessor _UserProcessor { get; set; } public UserProcessorDecorator(IUserProcessor userprocessor) { this._UserProcessor = userprocessor; } public void RegUser(User user) { BeforeProceed(user); this._UserProcessor.RegUser(user); AfterProceed(user); } /// <summary> /// 业务逻辑之前 /// </summary> /// <param name="user"></param> private void BeforeProceed(User user) { Console.WriteLine("方法执行前"); } /// <summary> /// 业务逻辑之后 /// </summary> /// <param name="user"></param> private void AfterProceed(User user) { Console.WriteLine("方法执行后"); } } }
