 自定义的切面

注解形式的aop 写着 切面上

1 package cn.itcast.spring.aop.annotation.sh; 2  3 import org.aspectj.lang.JoinPoint; 4 import org.aspectj.lang.ProceedingJoinPoint; 5 import org.aspectj.lang.annotation.AfterReturning; 6 import org.aspectj.lang.annotation.Aspect; 7 import org.aspectj.lang.annotation.Before; 8 import org.aspectj.lang.annotation.Pointcut; 9 import org.hibernate.Transaction;10 import org.springframework.stereotype.Component;11 12 13 /**14  * @Aspect15  * ==16  * 
     
       17  *      
      21  * 
     22  * @author Think23  *24  */25 @Component("myTransaction")26 @Aspect27 public class MyTransaction extends HibernateUtils{28     private Transaction transaction;29     30     @Pointcut("execution(* cn.itcast.spring.aop.annotation.sh.PersonDaoImpl.*(..))")31     private void aa(){}//方法签名  返回值必须是void  方法的修饰符最好是private ，aa是随便定义的 做类比32     33     @Before("aa()")34     public void beginTransaction(JoinPoint joinpoint){35         this.transaction = sessionFactory.getCurrentSession().beginTransaction();36     }37     38     @AfterReturning(value="aa()",returning="val")39     public void commit(Object val){40         this.transaction.commit();41     }42     43 }
