PropertySource
implementation that extracts properties from a Properties
object. Note that because a Properties
object is technically an <Object, Object>
Hashtable
, one may contain non-String
keys or values. This implementation, however is restricted to accessing only String
-based keys and values, in the same fashion as Properties.getProperty
and Properties.setProperty
.
