Resource.isFile() and JAF MediaTypeFactory [SPR-14484]

[spring-projects-issues]

Juergen Hoeller opened SPR-14484 and commented

Two common delegates have been in demand for a while and are now strongly suggested by our reactive efforts:

• A Resource.isFile() indicator for whether Resource.getFile() would succeed. This can make use of default methods in the interface, like isReadable() and isOpen().

• A MediaTypeFactory in org.springframework.http, resolving content type values to MediaType instances via the Java Activation Framework (remaining an implementation detail).
