Question

In my serviceImpl class I create a custom field with the @BeanReference for Dependency Injection as bellow

@BeanReference(type=PersistenceClass.class)
private PersistenceClass persistenceField;

My PersistenceClass is an interface with an Implementation : PersistenceImplClass and I create a bean in module-spring.xml

<bean id="com.example.persistence.PersistenceClass" class="com.exemple.persistence.impl.PersistenceImplClass">

I set the attribute dependency-injector="spring" in my service.xml

However, my persistenceField is null

Please is some body Have an idea ?
