The description of what you are looking for can be found here. But be wary about using such approach, some of the caveats of it are also described.
可以在此处找到您要查找的内容的说明。但是要小心使用这种方法，还描述了它的一些注意事项。
Also, the retention policy of the annotation has to be runtime, for this.
此外，注释的保留策略必须是runtime，为此。
The link in the comment to your question leads to a post that lookslike something you are asking about, but the difference is that it is about a JPA/Hibernate annotation where in the run-time you get a proxyclass to your class.
评论中指向您的问题的链接指向的帖子看起来像您正在询问的内容，但不同之处在于它是关于 JPA/Hibernate 注释的，其中在运行时您会获得类的代理类。
