spring - 所有 Spring-MVC Controller 的 ALPS 元数据

Question

我有一个关于 Spring hatoas/数据休息中的 ALPS 支持的问题。似乎只有在您拥有 Spring 数据休息存储库时才会公开 ALPS 元数据。所以我的问题是为什么只支持 spring 数据休息存储库，我可以为所有 spring mvc Controller 启用它吗？是否有任何示例可以公开所有 Controller 的 ALPS 元数据？

可能我没理解ALPS的概念...

问候

这只是部分回答了这个问题，但 Oliver Gierke 在上面链接的博客文章的评论中回答了以下问题:

Because it relies on the knowledge of which kinds of links you expose, how you name them and which HTTP methods are supported. With a plain Spring MVC application all of this is out of control of the framework, hence we can't provide it out-of-the-box.

However, Spring HATEOAS contains API to write custom Alps descriptors so that you can expose additional metadata that describe your controllers manually.
