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 }
Spring.Net Aop xml配置方式:(正则表达式确定方法)
