execution: AspectJ與Spring AOP 都支持:
- execution(public **(…)) 切入點爲執行所有public方法時
- execution(* set*(..)) 切入點爲執行所有set開始的方法時
- execution(* com.xyz.service.AccountService.*(..)) 切入點爲執行AccountService類中的所有方法時
- execution(* com.xyz.service..(..)) 切入點爲執行com.xyz.service包下的所有方法時
- execution(* com.xyz.service…(. .)) 切入點爲執行com.xyz.service包及其子包下的所有方法時
以下只有Spring AOP才支持
- within(com.xyz.service.*) (only in Spring AOP)
- within(com.xyz.service..*) (only in Spring AOP)
within 用於匹配指定類型內的方法執行 - this(com.xyz.service.AccountService) (only in Spring AOP)
this 用於匹配當前AOP代理對象類型的執行方法 - targer(com.xyz.service.AccountService) (only in Spring AOP)
targer 用於匹配當前目標對象類型的執行方法 - args(java.io.Serializable) (only in Spring AOP)
@target(org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
args 用於匹配當前執行的方法傳入的參數爲指定類型的執行方法 - @within(org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
- @annotation(org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
