Configure an object provided by a Guice Module

Question

I have a Module that provides a JDBI DBI instance like this:

@Provides
@Singleton
DBI dbi(DataSource dataSource) { return new DBI(dataS         


        

Answer 1

The Guice Injections documentation describes how to invoke an instance method by annotating the method with @Inject.

It doesn't mention that the instance can be a Guice module. As such, you can do this:

class MyConfigurationModule extends AbstractModule {
  @Override
  protected void configure() {
    requestInjection(this);
  }

  @Inject
  void configureDbi(DBI dbi) {
    // Do whatever configuration.
  }  
}
