Support injecting resource as Reader [SPR-12876]

[spring-projects-issues]

Christopher Smith opened SPR-12876 and commented

I am using the ability to inject an InputStream from the classpath, a la

@Autowired
MyConstructor(@Value('classpath:foo.csv') InputStream csv)

It would be convenient to be able to work with the resource as a Reader instead of an InputStream, but Spring doesn't know how to translate the string value into a Reader. Would it be feasible to have the conversion system understand how to wrap an InputStreamReader around the injected resource?

I'd recommend using EncodedResource for that purpose, created from an injected Resource, but when you're ok with the default charset, injecting a Reader is alright too. Addressed for 4.2 now.
