SpringContext ServiceLocatorFactoryBean Sınıfı

Giriş

Şu satırı dahil ederiz

import  org.springframework.beans.factory.config.ServiceLocatorFactoryBean;

Örnek

Elimizde bir arayüz ve bunun iki tane gerçekleştirimi olsun

public interface TourService {
  public String place(TourAdvicer request);
}

@Service("Singapore")
public class Singapore implements TourService {
  @Override
  public String place(TourAdvicer request) {
    ...
  }
}

@Service("Maldives")
public class Maldives implements TourService {
  @Override
  public String place(TourAdvicer request) {
    ...
  }
}

Bean ismine göre bulmak için bir registry yaratırız. Şöyle yaparız

public interface TourRegistry {
  public TourService getServiceBean(String serviceName);
}

//Now we need to register this registry class in our service locator 
// to get the desired bean config on run time
@Configuration
public class ServiceLocatorConfig {

  @Bean
  public FactoryBean<?> getBean() {
    ServiceLocatorFactoryBean bean = new ServiceLocatorFactoryBean();
    bean.setServiceLocatorInterface(TourRegistry.class);
    return bean;
  }
}

Şöyle yaparız

@Autowired
TourRegistry registry;

public String paymentAmount(@RequestBody String placeOfVisit) {
  return registry.getServiceBean(placeOfVisit).place(request);
}
