我的项目中有两种类型的注解:Annotation1
和 Annotation2
.两者都是运行时注释.所以,我的问题是如何只保留 Annotation1
并剥离 Annotation2
?
I have two types of annotation in my project: Annotation1
and Annotation2
. Both are runtime annotations. So, my question is how to keep only Annotation1
and strip Annotation2
?
例子:
class Test {
@Annotation1
@Annotation2
String name;
}
我希望从所有字段中删除 Annotation2
并在任何地方保留 Annotation1
.
I want Annotation2
to be removed from all fields and Annotation1
to be kept everywhere.
我找不到这是否可能.我只知道如何使用以下方法保留所有注释:
I can't find whether this is possible. I only know how to keep all annotations using:
-keepattributes *Annotation*
这可能吗?如果不是,为什么?
Is this possible? If not, why?
如果相应的注解类没有在其他地方使用(检索、转换、调用...),ProGuard 会自动从类/字段/方法中删除注解.您不能强制 ProGuard 删除注释,但可以告诉它保留看似未使用的注释:
ProGuard automatically removes annotations from the classes/fields/methods if the corresponding annotation classes are not used (retrieved, cast, invoked,...) elsewhere. You can't force ProGuard to remove annotations, but you can tell it to keep seemingly unused annotations:
-keep @interface com.example.MyAnnotation
这篇关于使用 proguard 保留特定注释的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
