As I recently learned in this group: Guice does not allow n:1 bindings. So you have an option to either: - define named bindings for the thousands of service classes - define a factory class with a method that takes a string and returns the service instance. Then you just need to bind an implementation of the factory that uses your reflection code.
I guess the last option can be enhanced to support injecting dependencies in the service by injecting the Injector in the Factory implementation and using it to get an instance of the service.
