Summary: Auto-loading of Cayenne modules
Key: CAY-2166
URL: https://issues.apache.org/jira/browse/CAY-2166
Project: Cayenne
Issue Type: Improvement
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
We need to borrow the central modularity feature from bootique.io - module
auto-loading based on Java ServiceLoader:
1. Each module in Cayenne (or custom modules if a user so desires) will ship
with "META-INF/services/org.apache.cayenne.di.spi.ModuleProvider" file that
will contain the name of the provider class.
2. Provider will contain a factory method for the module, as well as a method
that returns a collection of modules that this module "overrides"
3. There will be a loader class that will load all providers via
"java.util.ServiceLoader", create modules for each provider and then sort them
in the order of override dependencies.
4. ServerRuntimeBuilder will contain a method to turn auto-loading on and off.
"on" will be the default.
