New issue 758 by [email protected]: Increase support for optional
injection.
http://code.google.com/p/google-guice/issues/detail?id=758
Setter/field injection already has the ability to say @Inject(optional =
true), but it is impossible to reproduce this 'optional' behavior when
messing with a TypeListener.
I'm writing a tiny piece of code that uses spring-security, but wanted to
do injection via Guice. Many of the types have @Autowired setters and a few
of them have "required = false", but technically would have those objects
injected into them (from Spring).
So, to get this to work, I wanted to introduce a concept of an
OptionalProvider which is a wrapper around a Provider that simply
returns 'null' if the provider fails to supply a value.
Here's the code (it's a singular commit: 10 files, +116, -6):
