包内所有方法的@AspectJ 切入点 [英] @AspectJ pointcut for all methods inside package
问题描述
我有一个特定包的工作代码,但我想为所有控制器、服务和dao包配置它例如
I have this working code for a specific package, but i want to configure it for all controllers, service and dao packages Eg
- com.abc.xyz.content.controller
- com.abc.xyz.content.service
- com.abc.xyz.content.dao
- com.abc.xyz.category.controller
- com.abc.xyz.category.service
- com.abc.xyz.category.dao
等等...这是我的项目的基本包,有人可以帮助我如何去做,以便它适用于我的网络项目的所有类,包括控制器,在此先感谢...
and so on. . . that is the base package of my project, can someone please help how I can go about doing it so that it works for all classes of my web project including controllers, thanks in advance. . .

推荐答案
这些替代方案之一怎么样?
How about one of these alternatives?
A) 具有包限制的通用执行切入点:
execution(* *(..)) &&
(
within(com.abc.xyz..controller..*) ||
within(com.abc.xyz..service..*) ||
within(com.abc.xyz..dao..*)
)
B) 包限制的执行切入点:
execution(* com.abc.xyz..controller..*(..)) ||
execution(* com.abc.xyz..service..*(..)) ||
execution(* com.abc.xyz..dao..*(..))
顺便说一下,我更喜欢 B,因为它更短更容易阅读.正如您可能已经猜到的那样,..
表示法的意思是任何包或子包",而 *
位于表达式末尾的 ..
之后表示任何类中的任何方法".
I prefer B, by the way, just because it is a bit shorter and easier to read. As you have probably guessed, the ..
notation means "any package or subpackage", whereas *
at the end of the expression after ..
means "any method in any class".
