spring-rest-docs是一個測試驅動的spring組件，他能生成測試成功的接口進行文檔生成，支持markdown的轉換或者html的轉化，對於文檔對接，其實也夠了，缺點就是無法像其他工具那樣模擬測試數據，前端在對接的時候，可以直接調用模擬數據，尤其對於趕進度的接口，可能是先寫接口，再寫實現，那么這樣的話，就有點不適合。
但他的強大之處，就是可以自動生成文檔，而且是經過測試過的接口，減去一些不必要的撰寫工作，相對於Swagger來說，沒有任何代碼的依賴侵入。所以在實際的spring那套開發框架下，還是建議使用，他確實很不錯。如果真的需要用到其他系統化的api管理工具，可以把markdown再導入到管理工具中去，即可。
