Class GuiceFeature

java.lang.Object

ru.vyarus.dropwizard.guice.module.jersey.GuiceFeature

All Implemented Interfaces:

jakarta.inject.Provider<org.glassfish.jersey.internal.inject.InjectionManager>, jakarta.ws.rs.core.Feature

public class GuiceFeature
extends Object
implements jakarta.ws.rs.core.Feature, jakarta.inject.Provider<org.glassfish.jersey.internal.inject.InjectionManager>

Feature activates guice integration.

Guice context is created first and it doesn't depend on jersey start. First of all this allow using guice in commands and second, guice is ready in time of jersey initialization and so can provide it's own instances into jersey config.

Feature must be registered in jersey before it's start: environment.jersey().register(new GuiceFeature())

During guice context start special jersey bindings module registered GuiceBindingsModule, which lazily binds jersey specific types to guice context. This types could be used in guice only after actual integration (this feature activation)

HK2-guice bridge is activated when GuiceyOptions.UseHkBridge option enabled (not bi-directional). By default, it's disabled because most cases does not require it: it was developed for cases when bean is created by HK2 and only need some injections from guice, but here guice controls almost everything and prepared instance is passed to guice. But bridge may be useful together with JerseyManaged instances.

Feature installs ru.vyarus.dropwizard.guice.module.jersey.hk2.InstallerBinder, which is HK2 module. Just like with guice (BindingInstaller), it asks all JerseyInstaller to bind extensions into HK2 context.
