java interface有多个implement的情况下，@Inject调用实现类的选择

public interface InterfaceService<T extends BaseObject> {

    void getServiceName(T t);

}

public class AImplementService implements InterfaceService<AObject> {

    @Override
    public void getServiceName(AObject a) {
        System.out.println("AImplementService.getServiceName");
    }

}

public class BImplementService implements InterfaceService<BObject> {

    @Override
    public void getServiceName(BObject b) {
        System.out.println("BImplementService.getServiceName");
    }

}

public class InterfaceServiceTest {

    @Inject
    InterfaceService<AObject> serviceA;

    @Inject
    InterfaceService<BObject> serviceB;

    @Test
    public void test() {
        serviceA.getServiceName(new AObject());
        serviceB.getServiceName(new BObject());
    }

}
