我有一个关于特定包的工作代码,但我想将其配置为所有控制器、服务和数据访问对象(dao)包,例如:
- 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...那是我的项目的基础包,可以有人帮我解决如何让它适用于我的 Web 项目中的所有类,包括控制器,谢谢提前。

within()
切入点表达式,对吧?我认为对于嵌套类,within()
可以简化表达式(有时是极其简单的),但除此之外它只是一个方便的切入点描述符。 - Behrangwithin
匹配的连接点类型比仅仅是execution
更多,例如call
、get
、set
、initialization
、staticinitialization
等。它还匹配构造函数执行,而使用execution
切入点时,构造函数执行具有不同的语法。 - kriegaex
