public @interface Anno {
    int m() default x;
    int x = 10;
}

public @interface Anno {
    public int m() default x;
    public static final int x = 10;
}

解决方法@H_502_21@

是的,我相信你是对的 – 我发现支持这一点的一点文件是在 JLS 9.6：

Unless explicitly modified herein,all of the rules that apply to normal interface declarations apply to annotation type declarations.

所以它基本上表现得像普通的接口,其中public和abstract是冗余的,所有字段都是隐式静态和最终的.
