pointcut

execution: AspectJ与Spring AOP 都支持:

  • execution(public **(…)) 切入点为执行所有public方法时
  • execution(* set*(..)) 切入点为执行所有set开始的方法时
  • execution(* com.xyz.service.AccountService.*(..)) 切入点为执行AccountService类中的所有方法时
  • execution(* com.xyz.service..(..)) 切入点为执行com.xyz.service包下的所有方法时
  • execution(* com.xyz.service…(. .)) 切入点为执行com.xyz.service包及其子包下的所有方法时

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 用于匹配指定类型内的方法执行
  • this(com.xyz.service.AccountService) (only in Spring AOP)
    this 用于匹配当前AOP代理对象类型的执行方法
  • targer(com.xyz.service.AccountService) (only in Spring AOP)
    targer 用于匹配当前目标对象类型的执行方法
  • args(java.io.Serializable) (only in Spring AOP)
    @target(org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
    args 用于匹配当前执行的方法传入的参数为指定类型的执行方法
  • @within(org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
  • @annotation(org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
  • @args(com.xyz.security.Classified) (only in Spring AOP)
  • bean(tradeService) (only in Spring AOP)
