execution(public * *(..))

execution(* set*(..))

攔截AccountService(類、接口)中定義的所有方法
execution(* com.xyz.service.AccountService.*(..))

攔截com.xyz.service包中所有類中任意方法，**不包含**子包中的類
execution(* com.xyz.service.*.*(..))

攔截com.xyz.service包或者子包中定義的所有方法
execution(* com.xyz.service..*.*(..))

攔截service包中任意類的任意方法
within(com.xyz.service.*)

攔截service包及子包中任意類的任意方法
within(com.xyz.service..*)

目標對象使用aop之后生成的代理對象必須是指定的類型才會被攔截，注意是目標對象被代理之后生成的代理對象和指定的類型匹配才會被攔截
this(com.xyz.service.AccountService)

@EnableAspectJAutoProxy(proxyTargetClass = true)
proxyTargetClass=true表示強制使用cglib來生成代理對象

target(com.xyz.service.AccountService)
目標對象為AccountService類型的會被代理

匹配只有一個參數(shù)，且類型為
com.ms.aop.args.demo1.UserModel@Pointcut("args(com.ms.aop.args.demo1.UserModel)")

- 匹配多個參數(shù)
args(type1,type2,typeN)

匹配第一個參數(shù)類型為com.ms.aop.args.demo1.UserModel的所有方法, .. 表示任意個參數(shù)
@Pointcut("args(com.ms.aop.args.demo1.UserModel,..)")

目標對象中包含com.ms.aop.jtarget.Annotation1注解，調(diào)用該目標對象的任意方法都會被攔截
@target(com.ms.aop.jtarget.Annotation1)

聲明有com.ms.aop.jwithin.Annotation1注解的類中的所有方法都會被攔截
