See tests for understand how aspects in spring work.

• Pointcut: the expression used to define when a call to a method should be intercepted. In the above example, execution(* example.aop.typepointcut.packagge.notallowaccess..(..)) is the pointcut.
• Advice: What do you want to do? An advice is the logic that you want to invoke when you intercept a method. In the above example, it is the code inside the before(JoinPoint joinPoint) method.
• Aspect: A combination of defining when you want to intercept a method call (Pointcut) and what to do (Advice) is called an Aspect.
• Join Point: When the code is executed and the condition for pointcut is met, the advice is executed. The Join Point is a specific execution instance of an advice.
• Weaver: Weaver is the framework that implements AOP — AspectJ or Spring AOP.

• For all methods all classes for package example.aop.typepointcut.packagge.notallowaccess

"execution(* example.aop.typepointcut.packagge.notallowaccess.*.*(..))"

• For all methods class example.aop.typepointcut.clazz.FlowerDontTouch:

"execution(* example.aop.typepointcut.clazz.FlowerDontTouch.*())"

• For method getPassword() class example.aop.typepointcut.method.User:

"execution(* example.aop.typepointcut.method.User.getPassword())"

• For annotation "RangeValidate"

"@annotation(example.customannotation.RangeValidate)"
