Spring.Net Aop

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

BeforeAdvice

 1     using System.Reflection;
 2     using Spring.Aop;
 3     public class  BeforeAdvice : IMethodBeforeAdvice
 4     {
 5         public void Before(MethodInfo method , object[] args , object target)
 6         {
 7             Console.Out.WriteLine("[BeforeAdvice]  method : " + method.Name);
 8             Console.Out.WriteLine(" Target : " + target);
 9             Console.Out.Write("    The arguments are   : ");
10             if(args != null)
11             {
12                 foreach(object arg in args)
13                 {
14                     Console.Out.Write(arg+"\t ");
15                 }              
16             }
17             Console.Out.WriteLine();
18         }
19     }

AfterAdvice

 1     using System.Reflection;
 2     using Spring.Aop;
 3     public class  AfterAdvice : IAfterReturningAdvice
 4     {
 5         public void AfterReturning(
 6             object returnValue , MethodInfo method , object[] args , object target)
 7         {
 8             Console.Out.WriteLine("[AfterAdvice]  method : " + method.Name);
 9             Console.Out.WriteLine("    Target  : " + target);
10             Console.Out.Write("    The arguments : ");
11             if(args != null)
12             {
13                 foreach(object arg in args)
14                 {
15                     Console.Out.Write(arg+"\t ");
16                 }              
17             }
18             Console.Out.WriteLine();
19             Console.Out.WriteLine("    The return value is : " + returnValue);
20         }
21     }

AroundAdvice

 1    using AopAlliance.Intercept;
 2     public class AroundAdvice : IMethodInterceptor
 3     {
 4         public object Invoke(IMethodInvocation invocation)
 5         {   
 6             Console.WriteLine("开始:  " + invocation.TargetType.Name + "." + invocation.Method.Name);
 7             object result = invocation.Proceed();
 8             Console.WriteLine("结束:  " + invocation.TargetType.Name + "." + invocation.Method.Name);
 9             return result;
10         }
11     }

ThrowsAdvice

1   public class  ThrowsAdvice : IThrowsAdvice
2     {
3         public void AfterThrowing(Exception ex)
4         {
5             Console.Error.WriteLine(
6                 String.Format("Advised method threw this exception : {0}" , ex.Message));
7         }
8     }

数据模型(测试数据)

IDataModel

1  public interface IDataModel
2     {
3         IList FindAll();
4         object FindOne(string id);
5         void Save(object entity);
6     }

ProductModel

 1   public class ProductModel : IDataModel
 2     {
 3         public IList FindAll()
 4         {
 5             return new ArrayList();
 6         }
 7 
 8         public object FindOne(string id)
 9         {
10             //int i=100;
11             //if(i==100)
12             //  {
13             //        throw new Exception("aaa");
14             //  }         
15 
16             return new object();
17         }
18 
19         public void Save(object entity)
20         {
21             Console.WriteLine("保存：" + entity);
22         }
23     }

Spring.Net Aop 硬编码方式:

硬编码方式

 1   using Spring.Context;
 2     using Spring.Context.Support;
 3 
 4     using Spring.Aop.Framework;
 5     class Program
 6     {
 7         static void Main(string[] args)
 8         {
 9             Console.WriteLine("硬编码：");
10             //// 创建代理工厂
11             ProxyFactory factory = new ProxyFactory(new ProductModel());
12 
13             var around=new AroundAdvice();
14             var before=new BeforeAdvice();
15             var after= new AfterAdvice();
16            
17             // 这边添加的是 所有调用函数 都添加通知
18             // factory.AddAdvice(after);
19             factory.AddAdvice(around);// 后面添加的 通知被包在里面
20             //factory.AddAdvice(before);
21 
22             Spring.Aop.Support.NameMatchMethodPointcutAdvisor aspect_around=new Spring.Aop.Support.NameMatchMethodPointcutAdvisor(after);
23             aspect_around.MappedName="FindA*";
24             factory.AddAdvisor(aspect_around);
25 
26             Spring.Aop.Support.NameMatchMethodPointcutAdvisor aspect_before=new Spring.Aop.Support.NameMatchMethodPointcutAdvisor(before);
27             aspect_before.MappedName="FindO*";
28             factory.AddAdvisor(aspect_before);
29 
30             //// 创建代理对象
31             IDataModel command = (IDataModel)factory.GetProxy();
32             command.FindOne("888");
33             Console.WriteLine();
34 
35             command.FindAll();
36             Console.WriteLine();
37 
38             command.Save("内容");
39             Console.WriteLine();
40             Console.ReadKey();
41         }
42     }
