我有针对特定软件包的此工作代码,但我想为所有控制器,服务和 dao 软件包配置它 例如
等等。 。 。 这是我的项目的基础包,有人可以帮助我如何做到这一点,以便它适用于我的网络项目的所有类,包括控制器,提前感谢。 。

其中一种替代品怎么样?
A)包裹限制的一般执行切入点:
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,..
符号表示“任何包或子包”,而*
之后的..
表示“任何类中的任何方法”。

你只需要将你的切点改为:
@Pointcut("within(com.abc.*)")
进一步阅读 - https://docs.spring.io/spring/docs/2.0.x/reference/aop.html
答案 2 :(得分:0)
另一种选择是使用
@Pointcut("bean(*Controller)")
但是你的bean的命名应该是对应的
