Class ResteasyCdiExtension

java.lang.Object

org.jboss.resteasy.cdi.ResteasyCdiExtension

All Implemented Interfaces:

javax.enterprise.inject.spi.Extension

public class ResteasyCdiExtension
extends Object
implements javax.enterprise.inject.spi.Extension

This Extension handles default scopes for discovered JAX-RS components. It also observes ProcessInjectionTarget event and wraps InjectionTargets representing JAX-RS components within JaxrsInjectionTarget. Furthermore, it builds the sessionBeanInterface map which maps Session Bean classes to a local interface. This map is used in CdiInjectorFactory during lookup of Sesion Bean JAX-RS components.

observeBeforeBeanDiscovery

public void observeBeforeBeanDiscovery(@Observes
                                       javax.enterprise.inject.spi.BeforeBeanDiscovery event,
                                       javax.enterprise.inject.spi.BeanManager beanManager)

Obtain BeanManager reference for future use.

Parameters:

event - event

beanManager - bean manager

observeResources

public <T> void observeResources(@Observes
                                 javax.enterprise.inject.spi.ProcessAnnotatedType<T> event,
                                 javax.enterprise.inject.spi.BeanManager beanManager)

Set a default scope for each CDI bean which is a JAX-RS Resource.

Type Parameters:

T - type

Parameters:

event - event

beanManager - bean manager

observeProviders

public <T> void observeProviders(@Observes
                                 javax.enterprise.inject.spi.ProcessAnnotatedType<T> event,
                                 javax.enterprise.inject.spi.BeanManager beanManager)

Set a default scope for each CDI bean which is a JAX-RS Provider.

Type Parameters:

T - type

Parameters:

event - event

beanManager - bean manager

observeApplications

public <T extends javax.ws.rs.core.Application> void observeApplications(@Observes
                                                                         javax.enterprise.inject.spi.ProcessAnnotatedType<T> event,
                                                                         javax.enterprise.inject.spi.BeanManager beanManager)

Set a default scope for each CDI bean which is a JAX-RS Application subclass.

Type Parameters:

T - type

Parameters:

event - event

beanManager - bean manager

wrapAnnotatedType

protected <T> javax.enterprise.inject.spi.AnnotatedType<T> wrapAnnotatedType(javax.enterprise.inject.spi.AnnotatedType<T> type,
                                                                             Annotation scope)

observeInjectionTarget

public <T> void observeInjectionTarget(@Observes
                                       javax.enterprise.inject.spi.ProcessInjectionTarget<T> event)

Wrap InjectionTarget of JAX-RS components within JaxrsInjectionTarget which takes care of JAX-RS property injection.

Type Parameters:

T - type

Parameters:

event - event

wrapInjectionTarget

protected <T> javax.enterprise.inject.spi.InjectionTarget<T> wrapInjectionTarget(javax.enterprise.inject.spi.ProcessInjectionTarget<T> event)

observeSessionBeans

public <T> void observeSessionBeans(@Observes
                                    javax.enterprise.inject.spi.ProcessSessionBean<T> event)

Observes ProcessSessionBean events and creates a (Bean class -> Local interface) map for Session beans with local interfaces. This map is necessary since RESTEasy identifies a bean class as JAX-RS components while CDI requires a local interface to be used for lookup.

Type Parameters:

T - type

Parameters:

event - event

getSessionBeanInterface

public Map<Class<?>,Type> getSessionBeanInterface()

getProviders

public List<Class> getProviders()

getResources

public List<Class> getResources()
