Annotation相关

Inherited的作用

用于修饰其他的Annotaion. 被修饰的Annotation在标注父类时，子类自动获得该标注:

@Inherited
public @interface MyAnnotation {}

public @interface MyAnnotation2 {}

@MyAnnotation
@MyAnnotation2
public class Base {}

public class Sub extends Base {}

Sub.class.getAnnotation(MyAnnotation.class) != null
Sub.class.getAnnotation(MyAnnotation2.class) == null
