Spring.Net Aop

Spring.Net 有四种通知： IMethodBeforeAdvice，IAfterReturningAdvice，IMethodInterceptor，IThrowsAdvice

    using System.Reflection;
    using Spring.Aop;
    public class  BeforeAdvice : IMethodBeforeAdvice
    {
        public void Before(MethodInfo method , object[] args , object target)
        {
            Console.Out.WriteLine("[BeforeAdvice]  method : " + method.Name);
            Console.Out.WriteLine(" Target : " + target);
            Console.Out.Write("    The arguments are   : ");
            if(args != null)
            {
                foreach(object arg in args)
                {
                    Console.Out.Write(arg+"\t ");
                }              
            }
            Console.Out.WriteLine();
        }
    }

    using System.Reflection;
    using Spring.Aop;
    public class  AfterAdvice : IAfterReturningAdvice
    {
        public void AfterReturning(
            object returnValue , MethodInfo method , object[] args , object target)
        {
            Console.Out.WriteLine("[AfterAdvice]  method : " + method.Name);
            Console.Out.WriteLine("    Target  : " + target);
            Console.Out.Write("    The arguments : ");
            if(args != null)
            {
                foreach(object arg in args)
                {
                    Console.Out.Write(arg+"\t ");
                }              
            }
            Console.Out.WriteLine();
            Console.Out.WriteLine("    The return value is : " + returnValue);
        }
    }

   using AopAlliance.Intercept;
    public class AroundAdvice : IMethodInterceptor
    {
        public object Invoke(IMethodInvocation invocation)
        {   
            Console.WriteLine("开始:  " + invocation.TargetType.Name + "." + invocation.Method.Name);
            object result = invocation.Proceed();
            Console.WriteLine("结束:  " + invocation.TargetType.Name + "." + invocation.Method.Name);
            return result;
        }
    }

  public class  ThrowsAdvice : IThrowsAdvice
    {
        public void AfterThrowing(Exception ex)
        {
            Console.Error.WriteLine(
                String.Format("Advised method threw this exception : {0}" , ex.Message));
        }
    }

数据模型(测试数据)

 public interface IDataModel
    {
        IList FindAll();
        object FindOne(string id);
        void Save(object entity);
    }

  public class ProductModel : IDataModel
    {
        public IList FindAll()
        {
            return new ArrayList();
        }

        public object FindOne(string id)
        {
            //int i=100;
            //if(i==100)
            //  {
            //        throw new Exception("aaa");
            //  }         

            return new object();
        }

        public void Save(object entity)
        {
            Console.WriteLine("保存：" + entity);
        }
    }

Spring.Net Aop 硬编码方式:

  using Spring.Context;
    using Spring.Context.Support;

    using Spring.Aop.Framework;
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("硬编码：");
            //// 创建代理工厂
            ProxyFactory factory = new ProxyFactory(new ProductModel());

            var around=new AroundAdvice();
            var before=new BeforeAdvice();
            var after= new AfterAdvice();
           
            // 这边添加的是 所有调用函数 都添加通知
            // factory.AddAdvice(after);
            factory.AddAdvice(around);// 后面添加的 通知被包在里面
            //factory.AddAdvice(before);

            Spring.Aop.Support.NameMatchMethodPointcutAdvisor aspect_around=new Spring.Aop.Support.NameMatchMethodPointcutAdvisor(after);
            aspect_around.MappedName="FindA*";
            factory.AddAdvisor(aspect_around);

            Spring.Aop.Support.NameMatchMethodPointcutAdvisor aspect_before=new Spring.Aop.Support.NameMatchMethodPointcutAdvisor(before);
            aspect_before.MappedName="FindO*";
            factory.AddAdvisor(aspect_before);

            //// 创建代理对象
            IDataModel command = (IDataModel)factory.GetProxy();
            command.FindOne("888");
            Console.WriteLine();

            command.FindAll();
            Console.WriteLine();

            command.Save("内容");
            Console.WriteLine();
            Console.ReadKey();
        }
    }
