It's a bit more work, but you could consider using assisted injection for
this kind of use-case. My typical pattern looks like this:
public class Example {
@Inject
public Example(@Assisted("host") String host
HttpClient httpClient,
...) {
...
}
/** This class is a Guice Assisted-Inject Factory. */
public static interface Factory {
Example newExample(@Assisted("host") String host);
}
}
...
public class ExampleModule {
void configure() {
bindFactory(Example.class, Example.Factory.class);
}
protected <T, F> void bindFactory(Class<T> klass, Class<F> factoryKlass) {
bindFactory(klass, klass, factoryKlass);
}
}
And then you can still use a provider method (if you prefer!) and then you
inject the factory and the settings.
@Provides
public Example someExample(Example.Factory factory, Settings settings) {
return factory.newExample(settings.getHost());
}
Hope that helps! I use this pattern a lot, but not often mixed with a
Provider -- usually I have a class that manages the multiple instances
key'ed by some name (like client or user).
