Currently I am using Postman with POST and GRAPHQL type queries.
I wish I could query the API with spring-boot.
First, I want to make it very, very simple to check that everything is working. I tried with httpURLConnection but no luck.
Could you advise me to do something quick?
Then use spring boot, what do you advise me to use?
Thanking you

I would suggest using some graphql client package instead of writing your own solution. You could use https://github.com/apollographql/apollo-android which is suitable for any Java application. More info can be found here: https://apollographql.com/docs/android/essentials/get-started-java

If it's possible, please provide some source code.

Yes can use the tensorflow Java API, doc here. And the java api is experimental.

If you are very new to J2EE than I would like to suggest first go through JSP and Servlet then you will be able to understand how servlet mapping work, what is web container and all.after getting idea about these thing it would be easy for you to deal with spring, as of now answer to your questions is seems to be broad category.

If your application has a lot of SQLs/procedures then you need help from your DBA team. They can migrate data as well as procedures etc.

#james i think you could use ContentNegotiationViewResolver for the type of requirement you have. The proper implementation you can get from this link

I'm looking around for a good solution for JSON-RPC either in JAVA and Javascript (both sides, but I don't mean it has to be the same project!).
Post your hints. I'd like a mainstream project with lot of examples around.
I've tried jsonrpc4j but I can't get it working with spring...
Wikipedia have list of JSON-RPC libraries in various languages.
You can use spring-json view to transfer data from client to server using JSON.
spring-json view
on the official website you will find a list of JSON-RPC libraries/Clients for all languages including java and javascript
