RxJava Observables support for Spring REST plugin

@restservice

Hi,

I would like to ask if there are plans to add support for RxJava within rest-spring plugin, before I create new one.

For now, if somebody's using Observables and annotation-generated @restservice, this code has to be constantly repeated:

Observable.fromCallable(new Callable<String>()
{
    @Override
    public String call() throws Exception
    {
        return testRestService.getIndex();
    }
})

It would be nice to return Observable from Rest interface, like this:

@Rest(
    // ...
)
public interface TestRestService
{

    @Get("/")
    Observable<String> getIndex();

}

I've tried to implement custom message converter, but with no luck. Compilation fails after using parameterized type as a result (as shown above):

error: constructor Observable in class Observable<T> cannot be applied to given types;
required: OnSubscribe<String>
found: no arguments
reason: actual and formal argument lists differ in length
where T is a type-variable:
T extends Object declared in class Observable

Looking forward to hearing from you.

afaik there is no such plan right now. but i think you could try to contribute that feature so there would be no need for a complete new plugin.

This was already requested in #1816, however i mark that one as a duplicate as this issue is better scoped. I agree this would be a great addition to AA-REST, but currently i do not have time to implement this. Contributions are welcome, as always!

@marcin-jelenski your issue is so cool

As soon as I have more time to dive into AA, I will try to contribute this module (and maybe others) to support react components.
