I'm using Wildfly 10, Jersey, and injecting dependencies with @Inject. I have DAO and Service interfaces with their implementations declared in a CustomBinder. The injections work well, but the EntityManager is injected null with the @PersistenceContext annotation. I'm using MySQL and the datasource test-connection is working.
API Rest class
@Path("/account")
public class CuentaServiceRS {
@Inject
private ICuentaService cuentaService;
@GET
@Produces(MediaType.APPLICATION_JSON)
public Cuenta getCuenta() {
return cuentaService.getCuentas().get(0);
}
}
The implementation of ICuentaService
@Stateless
public class CuentaServiceImpl implements ICuentaService {
@Inject
private ICuentaDAO cuentaDAO;
@Override
public List<Cuenta> getCuentas() {
List<Cuenta> cuentas = cuentaDAO.getAllCuentas();
cuentas;
}
}
The implementation of CuentaDAO
@Stateless
public class CuentaDAOImpl implements ICuentaDAO {
@PersistenceContext(unitName = "altitudePU")
protected EntityManager em;
@Override
public List<Cuenta> getAllCuentas() {
CriteriaQuery<Cuenta> cq = em.getCriteriaBuilder().createQuery(Cuenta.class);
/...
return resultlist;
}
}
My persistence-unit in persistence.xml
<persistence-unit name="altitudePU">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:jboss/datasources/AltitudePU</jta-data-source>
<class>ar.com.olx.domain.Cuenta</class>
<properties>
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
</properties>
</persistence-unit>
The servlet configured on web.xml
<servlet>
<servlet-name>altitudeservlet</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>ar.com.villat.bind.ApplicationJaxRS</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
My custom AplicationJaxRS which extendes from ResourceConfig
public class ApplicationJaxRS extends ResourceConfig {
public ApplicationJaxRS(){
register(new CustomBinder());
packages(true, "ar.com.olx");
}
}
The CustomBinder
public class CustomBinder extends AbstractBinder {
@Override
protected void configure() {
bind(CuentaServiceImpl.class).to(ICuentaService.class);
bind(CuentaDAOImpl.class).to(ICuentaDAO.class);
}
}
