## Uses of Class
org.springframework.core.env.PropertySource

- Packages that use PropertySource
  Package | Description
  --- | ---
  org.springframework.core.env | Spring's environment abstraction consisting of bean definition profile and hierarchical property source support.
  org.springframework.core.io.support | Support classes for Spring's resource abstraction.
