Interface ServiceLocator

All Known Implementing Classes:
ServiceRegistry
public interface ServiceLocator
Abstracts a dependency injection container for resolving services.

Implementations bridge Oorian to an external DI framework (Spring, CDI) or use the built-in ServiceRegistry. The active locator is configured via Services.setServiceLocator(ServiceLocator).

Built-in implementations:

Custom implementations (external modules):


 // Spring integration
 public class SpringServiceLocator implements ServiceLocator {
     private final ApplicationContext context;

     public SpringServiceLocator(ApplicationContext context) {
         this.context = context;
     }

     public <T> T get(Class<T> serviceClass) {
         return context.getBean(serviceClass);
     }

     public <T> boolean has(Class<T> serviceClass) {
         return context.getBeanNamesForType(serviceClass).length > 0;
     }
 }
