重复修饰符必须与其他模式组合，修饰符本身没有含义。
A repetition modifier must be combined with other patterns; the modifier has no meaning by itself.
首先，我将演示修饰符模式在Groovy中的传统实现，然后再在后续示例中提高它的动态性。
First, I'll show a traditional implementation of the Decorator pattern in Groovy, then make it more dynamic in subsequent examples.
示例中的切入点使用了修饰符（modifier）和通配符（wildcard）模式来表达“所有公共方法”。
The pointcut in the example uses a modifier and wildcard pattern to express "all public methods."
命令显示欲匹配的此类模式，修饰符可以改变此类匹配中发生的行为。
A command indicates a type of pattern to match, and a modifier can change the behavior that occurs in case of such a match.
