创建自定义注释作为框架注释的别名? [英] Create custom Annotation as alias for Framework-Annotation?

问题描述

是否可以创建自定义别名注释来代替

is it possible to create a custom Alias-Annotation to be used instead of

@SuppressWarnings("unused") // EventBus
public void onEvent(SomeMessage msg) { ... }

喜欢

@EventBusListener
public void onEvent(SomeMessage msg) { ... }

这将更加自我记录，当然应该包括 SuppressWarnings...对不起，如果这微不足道，但到目前为止我的谷歌搜索失败了.

This would be more self-documenting and should include the SuppressWarnings of course... Sorry if this trivial but my googling failed me so far.

推荐答案

您可以通过以下方式实现:

You can implement it following way :

@Target({ElementType.TYPE, ElementType.FIELD, ElementType.METHOD, ElementType.PARAMETER, ElementType.CONSTRUCTOR, ElementType.LOCAL_VARIABLE})
@Retention(RetentionPolicy.SOURCE)
@SuppressWarnings("unused")
public @interface EventBusListener{
    @AliasFor(annotation = SuppressWarnings.class, attribute = "value") String[] value() default {"unused"};
}
