Could I add a spring boot version of endpoints-v2-backend?

In which file did you encounter the issue?

https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine-java8/endpoints-v2-backend

Did you change the file? If so, how?

I can add a new endpoints-v2-backend-spring copy that closely resembles the linked project but uses JAR instead of WAR (which imo is the better file format) in conjunction with Spring Boot.

Describe the issue

The existing demo project is fine, although it’s really not beginner friendly and doesn’t teach best development practices since, AFAIK, there is no way to test it locally.

Using Spring allows you to simulate what’s being deployed by app engine on localhost.

I have my own more personalized version of the project working with GAE and GCF. (and of course maven + spring + jar)

Unfortunately we don’t yet support version 3.

A nice thing about this approach could also be that if Cloud Endpoints eventually supports openapi3, all you would have to do is remove the extra conversion plugin and you would already be at openapi 3, less a few configurations possibly.
