Support play for java and scala server.

[clasnake]

Description

Seems no support for play now.
Shall we support play for java and scala server, so that server-side code based on the play framework can be auto-generated according to the rest spec.

@clasnake we would definitely welcome contribution for a play framework server stub generator.

Here is a good starting point: https://github.com/swagger-api/swagger-codegen/wiki/How-to-add-a-generator-for-a-new-language-or-framework

@wing328 I'll take a look at this one. And shall we add label Server: Scala as well?

[clasnake]

@wing328 Well I see the play integration at https://github.com/swagger-api/swagger-play as a separate repo and https://github.com/zalando/play-swagger to generate play code from the spec. So I guess no need to add it into swagger-codegen?

@wing328 Thanks for pinging me.

Although that project (zalando/play-swagger) is from my company, I didn't use it until now (my team is using neither Play nor Scala).

Looking at the README, it seems to have a bit different approach than Swagger-Codegen. It is integrated in the Scala Build tool, generating both managed code (i.e. code which is generated in the target folder, which you shouldn't edit) and unmanaged code (code which you can edit, and which might get modified later by the plugin, keeping your edits). I'm not sure if the latter one would be possible at all with Swagger-Codegen's current architecture.

(Swagger-Play seems to be the Scala/Play version corresponding to Java's Swagger-annotations, generating Swagger/OpenAPI from Play code. This would be the inverse approach to play-swagger, though both names should be swapped to describe what they are doing.)

@clasnake Please check if the play-swagger generator works for you (and report any issues back to that repository's tracker). If it doesn't, having more ways to support end-to-end type safety (which is one of the reasons I want to have Swagger-generation) is always good, so you are welcome to contribute a generator here (though I can't really comment much on it, knowing Scala only very superficially – I don't like the syntax).
