问题描述
我有一个从基础接口扩展而来的服务层接口；我想围绕我的服务层接口创建一个切入点，但是在基本接口中定义的方法之一上.
I have a service-layer Interface that extends from a base Interface; I would like to create a Pointcut around my service-layer Interface, but on one of the methods defined in the base Interface.
例如......我在我的基本接口中有一个名为save()"的方法，我把它放在我的基本接口中，因为我所有的子"接口都将提供保存"功能.
For instance.... I have a method in my base Interface called "save()", I put it in my base Interface since just all of my "child" Interfaces will provide "save" functionality.
当我的保存"被调用时，我只想在我的一个子"界面上创建一个切入点.
I would like to create a PointCut on only one of my "child" interfaces for when my "save" gets called.
我创建的切入点如下:
@Pointcut("execution(* com.xyz.someapp.ChildServiceInterface.save(..))")
public void childServiceSavePointCut();
然后我围绕上述切入点创建了一个@Around 建议，如下所示:
I then created a @Around advice around the above pointcut like the following:
@Around("childServiceSavePointCut()")
public void doMyAdvice()....
其中ChildServiceInterface"扩展了另一个定义了save()"方法的接口.
where "ChildServiceInterface" extends another Interface which has the "save()" method defined.
我的建议从未运行...我调试了我的代码，但在目标服务的顾问列表中没有看到我的建议.
My Advice never runs... I debugged my code and do not see my Advice in the list of Advisors for my target service.
我是否认为这会奏效，还是我错误地实施了它?
Am I way off base thinking this will work, or am I implementing it incorrectly?
推荐答案
试试这个切入点.
within(com.xyz.someapp.ChildServiceInterface+) && execution(* save(..))
+ 表示子类型模式.
