Spring - Access a Service interface programmatically - spring

Question

i have several interfaces which extend a single interface.
I need to add, during a #PostCostruct method, these interfaces to a Map.
The problem is that i need to retrieve the #Service class name from the DB and i don't know ho to put the interface in the map...
I'll try to explain it better
I have a general service interface
public interface IVehicleServiceGeneral{
//methods...
}
then i have several interfaces which extend the general one.
public interface IService1 extends IVehicleServiceGeneral{
}
public interface IService2 extends IVehicleServiceGeneral{
}
the concrete implementations of these classes are annotated with #Service("service1Name"), #Service("service2Name") and so on...
Then from the DB i retrieve my Suppliers
public class Supplier {
private long id;
private String serviceName;
//getters and setters
}
Finally i need to create the map, because i need to access the implementations at runtime based on the Supplier, i created a ContextAware class to get my beans by name, but the interfaces are not beans... I also tried to put the #Qualifier on the interface, but obviously it does not work... How can I put the interface in the map?
#PostConstruct
private void createServiceMap(){
serviceMap = new HashMap<OBUSupplier, IVehicleServiceGeneral>();
List<Supplier> suppliers = supplierService.findAll();
for(Supplier s : suppliers) {
serviceMap.put(s, contextAware.getBean(s.getServiceName()));
}
}

Answer 1

You can create IVehicleServiceGeneral instance map like this:
class SomeClass {
Map vehicleServiceGeneralInstanceMap = new HashMap();
SomeClass(Set<IVehicleServiceGeneral> instances) {
instances.forEach(i -> vehicleServiceGeneralInstanceMap.put(i.getServiceName(), i));
}
private void createServiceMap() {
Map serviceMap = new HashMap<OBUSupplier, IVehicleServiceGeneral>();
List<Supplier> suppliers = supplierService.findAll();
for(Supplier s : suppliers) {
serviceMap.put(s, vehicleServiceGeneralInstanceMap.get(s.getServiceName()));
}
}
The only thing you require is IVehicleServiceGeneral#getServiceName which your Service1, 2 need to override with proper names that present in DB.
