  • let's talk about Property Source design

    hello,everyone:

    PropertySource is a abstract class,not interface. but most root class in spring is interface. WHY?
    ok,go to source code(spring 3.1):
    PropertySource objects are not typically used in isolation, but rather
    through a PropertySources object, which aggregates property sources and in
    conjunction with a PropertyResolver implementation that can perform
    precedence-based searches across the set of PropertySources
    seems like PropertySource was designed for internal use.
    what do you think?
