             Summary: Bootique-style module "extenders" for smoother configuration
                 Key: CAY-2772
                 URL: https://issues.apache.org/jira/browse/CAY-2772
             Project: Cayenne
          Issue Type: Task
            Reporter: Andrus Adamchik
            Assignee: Andrus Adamchik


I would like to make our runtime extensions API more user-friendly. 

1. Our current module "contribute" API in ServerModule was intended to expose DI collections to the users for extension. But is still too "technical".

2. Other modules (such as crypto and commitlog) already have extenders similar to Bootique extenders, but they produce Module instances (while Bootique extenders have a binder internally, and not building own Module). The Bootique approach seems less confusing, as service assembly still happens in the main module, and the extender simply provides building blocks for it.

I would like to unify that into something like this, which seems to be the most flexible format from Bootique experience:

{noformat}
ServerRuntime
   .builder()
   .addModule(b -> ServerModule.extend(b).addQueryFilter(MyFilter.class))
   .addModule(b -> CommitLogModule.extend(b).addListener(MyListener.class))
   .build();
{noformat}

I am working on a PR now.
