Spring REST Docs 

Document RESTful services by combining hand-written with Asciidoctor and auto-generated snippets produced with Spring MVC Test.

spring-rest-docs是一个测试驱动的spring组件，他能生成测试成功的接口进行文档生成，支持markdown的转换或者html的转化，对于文档对接，其实也够了，缺点就是无法像其他工具那样模拟测试数据，前端在对接的时候，可以直接调用模拟数据，尤其对于赶进度的接口，可能是先写接口，再写实现，那么这样的话，就有点不适合。

但他的强大之处，就是可以自动生成文档，而且是经过测试过的接口，减去一些不必要的撰写工作，相对于Swagger来说，没有任何代码的依赖侵入。所以在实际的spring那套开发框架下，还是建议使用，他确实很不错。如果真的需要用到其他系统化的api管理工具，可以把markdown再导入到管理工具中去，即可。
