2.LogAround

package com.gc.action;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;

public class LogAround implements MethodInterceptor {

    @Override
    public Object invoke(MethodInvocation arg0) throws Throwable {
        // TODO Auto-generated method stub
        
        Object result=null;
        
        try
        {
            System.out.println("aop 之前");
            result=arg0.proceed();
            
            return result;
        }
        
        finally{
            
            System.out.println("aop 之后");
            
        }
    
    }

}

3.TimeBook

package com.gc.action;

public class TimeBook implements ITimeBook {

    @Override
    public void doAudit(String name) {
        // TODO Auto-generated method stub
        System.out.println("laaaaaaaaaaaaa");
    }

}

4.ITimeBook

package com.gc.action;

public interface ITimeBook {

    public void doAudit(String name);
}

5. 测试

  ApplicationContext context=new FileSystemXmlApplicationContext("config-aop.xml");
          ITimeBook tb=(ITimeBook)context.getBean("logProxy");
          tb.doAudit("xiaox");
