After searching the web for a solution to create an injector with a module
with missing bindings I didn't find any discussion about that. Is there a
way to accomplish that? What I'm trying to do is to create a child injector
later on, which uses a module that provides the missing bindings and use
that injector to create objects. Example:
private static class DefaultModule extends AbstractModule
{
@Override
protected void configure()
{
bind(IClassA.class).to(ClassA.class);
/*
* ClassA needs an implementation for IClassB. The binding for
IClassB is not defined here.
*/
}
}
public final class ClassAFactory
{
private static final Injector injector = Guice.createInjector(new
DefaultModule());
/*
* Here the creation of the Injector fails, because the binding for
IClassB is missing
*/
public static IClassA createClassA()
{
Injector functionalInjector = injector.createChildInjector(new
AbstractModule()
{
@Override
protected void configure()
{
bind(IClassB.class).to(ClassB.class);
/*
* Here I would satisfy the missing binding
*/
}
});
return functionalInjector.getInstance(IClassA.class);
}
}
Thanks for any help!
