I have a class to be injected, which may through exception from its
constructor. As recommend in Guice wiki, I need to use CheckedProvider
into the catch and handler that exception. Following is how I do it:
// The interface
public interface Grape {
public void info();
}
// The implementation
public class GrapeImpl implements Grape {
public GrapeImpl() throws GrapeException {
}
@Override
public void info() {
}
}
// The CheckedProvider interface with get() throwing my own Exception
public interface FruitProvider<T> extends CheckedProvider<T> {
@Override
T get() throws GrapeException ;
}
// The Provider implementation
public class GrapeImplProvider implements FruitProvider<Grape> {
@Override
public Grape get() throws GrapeException {
return new GrapeImpl();
}
}
// The binding in my Module
ThrowingProviderBinder.create(binder()).bind(FruitProvider.class,
Grape.class).to(GrapeImplProvider.class).in(Singleton.class);
As you can see from the binding part, I want to add some scoping, as
in this case it's Singleton (or can also be RequestScoped). But
according to my testing, every time I call the get() of
GrapeImplProvider, a new instance of GrapeImpl is returned. I guess
the implementation in the get() may be wrong, but I don't how should I
implement it in order that my scoping requirement will be honored.
Thanks,
