The use I expected was along these lines:
router.attach(uriPattern, factory.finderFor(MyResource.class));
// "route a request to uriPattern to whatever is bound to MyResource in
Guice"
In the very common case that MyResource is the concrete resource class you
want to use, you don't have to bind it explicitly to itself in a Guice
module.
Private helper methods would make this easier to read:
router.attach("/policies/{id}", to(InsurancePolicyResource.class));
...
private Finder to(Class<? extends Handler> resourceClass) {
return getFactory().finderFor(resourceClass);
}
private synchronized FinderFactory getFactory() {
if (this.finderFactory == null) {
this.finderFactory = ... create FinderFactory here ...;
}
return this.finderFactory;
}
@GuardedBy("this") private FinderFactory finderFactory;
If, however, you have bound the same abstract resource type in different
ways for different annotations, you would use this approach:
router.attach(uriPattern,
factory.finderFor(Key.get(AbstractResource.class, SomeAnnotation.class)));
// "route a request to uriPattern to whatever is bound to
@SomeAnnotation AbstractResource in Guice"
I think this usage will be rare, but I didn't want to rule it out.
