 ## DI Usage
-The annotation processor will generate controller adapters to register routes to Javalin/Helidon. The natural way to use the generated adapters is to get a DI library to find and wire them. This is what the examples below do; they use [Avaje-Inject](https://avaje.io/inject/) to do this. The AP will automatically detect the presence of avaje-inject and generate the class to use avaje-inject's `@Component` as the DI annotation.

-There isn't a hard requirement to use Avaje for dependency injection. In the absence of avaje-inject, the generated class will use `@jakarta.inject.Singleton` or `@javax.inject.Singleton` depending on what's on the classpath. Any DI library that can find and wire the generated @Singleton beans can be used. You can even use Dagger2 or Guice to wire the controllers if you so desire.
