private static class GetterMethodMatcher extends StaticMethodMatcher {
public boolean matches(Method method, Class<?> cls) {
return (method.getName().startsWith("get"));
}
}
private static class GetAgeMethodMatcher extends StaticMethodMatcher {
public boolean matches(Method method, Class<?> cls) {
return "getAge".equals(method.getName());
}
}
private static class SetterMethodMatcher extends StaticMethodMatcher {
public boolean matches(Method method, Class<?> cls) {

}
}
}
The first thing to notice in this example is the set of three private MethodMatcher implementations.
The GetterMethodMatcher matches all methods that start with get. This is the default MethodMatcher that
we use to assemble the ComposablePointcut. Because of this, we expect that the first round of invocations
on the SampleBean methods will result in only the getAge() and getName() methods being advised.
