It is troublesome to get parameters from path in the current framework. Should we introduce other REST frameworks?

If it's too much trouble, I'm OK with current route path. If it's simple, I prefer the above REST path, which is more idiomatic. It's up to you.

There will be more and more rest apis in the future. It is still troublesome to add an api under the current framework. So I think we can consider it later. How about introduce Jersey? @advancedxy @jerqi @zuston @kaijchen

I'm not familiar with Jersey. Is it lightweight enough? Is it used widely?

Yes. Hadoop and Spark use Jersey either.

I don't know if

is lightweight. I hope the restful framework could be modern and lightweight.There was a problem hiding this comment.

I'm ok with current status. Let's make the new REST server framework a followup PR. Jersey itself seems a bit complex, but the path annotation https://eclipse-ee4j.github.io/jersey.github.io/documentation/latest/user-guide.html#d0e2081 is quite elegant.

Maybe we can refer to Apache Livy, it use
scalatra
. We can use similar Java framework.https://www.51cto.com/article/311366.html
