Method Detail

registerInjector

public static io.dropwizard.lifecycle.Managed registerInjector(io.dropwizard.Application application,
                                                               com.google.inject.Injector injector)

Used internally to register application specific injector.

Parameters:

application - application instance

injector - injector instance

Returns:

managed object, which must be registered to remove injector on application stop

getInjector

public static java.util.Optional<com.google.inject.Injector> getInjector(io.dropwizard.Application application)

Parameters:

application - application instance

Returns:

optional with or without application-bound injector

clear

public static void clear()

Clears stored injectors references. Normally shouldn't be used at all, because managed object, returned on registration removes injector reference automatically on shutdown (for example, when used DropwizardAppRule or GuiceyAppRule). May be useful in tests, when application was not shut down properly.

WARNING: calling this method while application is working may cause incorrect behaviour.
