jar - Inyectando un frijol de un tarro diferente en Weld

cdi ear

Question

Tengo dos tarros A y B donde A depende de B.

Jar B tiene una sola clase:

@ApplicationScoped
public class MyManagedBean {
private String user;
public MyManagedBean(){
//Constructor necesary for CDI
}
@Inject
public MyManagedBean(@Named("user") String user){
this.user = user;
}
...
}

Jar A (más precisamente, un jar EJB) tiene un bean:

@ApplicationScoped
public class AnotherManagedBean {
public AnotherManagedBean(){
//Constructor necesary for CDI
}
@Inject
public AnotherManagedBean(MyManagedBean bean){
...
}
}

Y un bean de configuración con un método @Produces:

@ApplicationScoped
public class ConfigurationBean {
public ConfigurationBean(){
//Constructor necesary for CDI
}
@Produces
@Named("user")
public String getUser(){
return "myUser";
}
}

Sin embargo, cuando implemento un EAR con ambos Jars obtengo esta excepción:

SEVERE: Exception while loading the app : WELD-001408 Unsatisfied dependencies for type [String] with qualifiers [@Named] at injection point [[parameter 1] of [constructor] @Inject public com.example.MyManagedBean(String)]

¿Alguna idea?

Answer 1

Asegúrese de que ambos archivos sean "archivos de bean", es decir, tienen META-INF/beans.xml

Answer 2

Estaba teniendo exactamente el mismo problema y pude resolverlo pero uso una oreja para combinar los frascos.

Diseño del oído

project.ear
|-- META-INF
| |-- MANIFEST.MF
| |-- application.xml*
|-- one.jar (bean archive)
| |-- META-INF
| | |-- beans.xml
| |-- <code>
|-- two.jar (ejb)

• application.xml

<application>
<display-name>test-application</display-name>
<module>
<ejb>two.jar</ejb>
</module>
<module>
<java>one.jar</java>
</module>
</application>

Haciendo eso, hizo que one.jar estuviera disponible para two.jar en el contenedor.

Answer 3

Una cosa, tiene que crear una anotación de Qulifier para especificar exactamente qué debe inyectarse.

@Qualifier
@Retention(RUNTIME)
@Target({METHOD, FIELD, PARAMETER, TYPE})
public @interface UserConfiguration { }

y entonces..

 @Produces
@UserConfiguration
@Named("user")
public String getUser(){
return "myUser";
}

para inyección ..

@Inject
public MyManagedBean(@UserConfiguration String user){
this.user = user;
}
