Java：如何将默认值设置为注释，并将另一个注释作为其属性？

Question

I have an annotation with 3 attributes:

public @interface Date {
    int day() default 1;
    int month() default 1;
    int year() default 2000;
}

And annotation that uses previous annotation as attribute:

public @interface Author {
    String name();
    Date date(); //default value here
}

How to set default value for attribute date ?

Answer 1

You do this by providing a default annotaion...

For example:

public @interface Author {
    String name();
    Date date() default @Date(year=2014);
}
