Interface Injection

If the type to inject is an interface, configure the net.hasor.core.ImplBy annotation on that interface to determine its concrete implementation class.

Example

@ImplBy(PayServiceImpl.class)
public interface PayService {
    ...
}

You can also declare the relationship between an interface and its implementation in code during module initialization.

AppContext appContext = Hasor.create().build(apiBinder -> {
    apiBinder.bindType(PayService.class).to(PayServiceImpl.class);
});

tip

The @ImplBy annotation is transitive. The target type of an ImplBy annotation can itself be annotated with @ImplBy again. @ImplBy can be placed on interfaces, abstract classes, and concrete classes.
