GuicedEE CDI

Lightweight Jakarta CDI bridge for GuicedEE applications.

Core Concept

Maps CDI annotations (@Inject, @Named, @ApplicationScoped, @Qualifier) to their Guice equivalents, provides a BeanManager adapter backed by the Guice injector, and registers itself as the Jakarta CDIProvider — so CDI-annotated code runs seamlessly inside a Guice-managed container.

Required Flow

Add com.guicedee:cdi dependency.

Annotate your classes with standard Jakarta CDI annotations:

@jakarta.enterprise.context.ApplicationScoped
public class GreetingService {
    public String greet(String name) {
        return "Hello, " + name + "!";
    }
}

Inject anywhere via @Inject:

public class WelcomeResource {
    @jakarta.inject.Inject
    private GreetingService greeter;
}

Configure module-info.java:

module my.app {
    requires com.guicedee.cdi;
}

Bootstrap GuicedEE — CDI module loads automatically:

IGuiceContext.registerModuleForScanning.add("my.app");
IGuiceContext.instance().inject();

Annotation Mapping

| CDI Annotation | Guice Equivalent | |---|---| | @jakarta.inject.Inject | @com.google.inject.Inject | | @jakarta.inject.Named | Names.named() | | @jakarta.inject.Singleton | Guice SINGLETON scope | | @jakarta.enterprise.context.ApplicationScoped | Guice SINGLETON scope | | @jakarta.inject.Qualifier | Guice binding annotation |

CDI Provider Chain

CDI.current()
 → JakartaCDIProvider.getCDI()
   → GuicedCDI.select(Class<T>)
     → IGuiceContext.get(Class<T>)  // Guice injector lookup

BeanManager

The GuiceCDIBeanManager provides a simplified bean lookup API:

@Inject
private GuiceCDIBeanManager beanManager;

MyService svc = beanManager.getBean(MyService.class);
MyService svc = beanManager.getBean(MyService.class, "primary"); // @Named
boolean exists = beanManager.containsBean(MyService.class);

SPI Providers

| SPI | Purpose | |---|---| | BindScopeProvision | @Singleton, @ApplicationScoped → SINGLETON | | InjectionPointProvision | @Inject, @Named, @PostConstruct detection | | BindingAnnotationsProvision | @Qualifier as binding annotation | | NamedAnnotationProvision | jakarta.inject.Named → Names.named() | | InjectorAnnotationsProvision | jakarta.inject.Inject recognition |

Non-Negotiable Constraints

Module must requires com.guicedee.cdi;.
The CDI module is loaded automatically — no provides needed in your application module.
Injection packages must opens to com.google.guice.
