切面编程AOP之Castle.Core

时间:2021-02-23 01:10:05

1.Nuget中搜索Castle.Core并install

2.创建一个普通的类(注意类中只有标记virtual才能实现拦截 )

 public class TestInterceptor
{
public virtual void MethodInterceptor()
{
Console.WriteLine("走过滤器");
} public void NoInterceptor()
{
Console.WriteLine("没走过滤器");
}
}

3. 创建拦截器

public class Interceptor: StandardInterceptor
{
protected override void PreProceed(IInvocation invocation)
{
Console.WriteLine("调用前的拦截器, 方法名是: {0}", invocation.Method.Name);
} protected override void PerformProceed(IInvocation invocation)
{
Console.WriteLine("拦截的方法返回时调用的拦截, 方法名是: {0}", invocation.Method.Name);
} protected override void PostProceed(IInvocation invocation)
{
Console.WriteLine("调用后的拦截器, 方法名是: {0}", invocation.Method.Name);
}
}

4. 控制台中调用

static void Main(string[] args)
{
#region Castle.Core
ProxyGenerator generator = new ProxyGenerator(); // 实例化代理生成器
Interceptor interceptor = new Interceptor(); //实例化拦截器 //使用代理生成器创建Person对象, 而不是使用new关键字实例化
TestInterceptor test = generator.CreateClassProxy<TestInterceptor>(interceptor);
Console.WriteLine("当前类型: {0}, 父类型: {1}", test.GetType(), test.GetType().BaseType);
Console.WriteLine();
test.MethodInterceptor();
Console.WriteLine();
test.NoInterceptor();
Console.WriteLine();
Console.ReadLine();
#endregion
}
