Improve @PropertySource loading support [SPR-12116]

[spring-projects-issues]

Marten Deinum opened SPR-12116 and commented

Recently we need to add support to load properties from a database and make those available to the Environment. Although not that hard (we used an ApplicationContextInitializer and added some PropertySources) it still requires some knowledge of the Spring Framework infrastructure.

Would it be possible to introdudce a loader attribute on the @PropertySource annotation in which you could specify a PropertySourcesLoader which in turn contains the strategy for loading that particuliar property source. The code from ConfigurationClassParser could load/instantiate this loader and delegate loading to it. A default implementation containing the current loading strategy could be added.

This would also allow for easier loading of for instance yaml, xml or json files.

Since this is somewhat complementary in terms of the use cases presented in #13603, I'm marking this as fixed along with it... just in case there are any follow-ups or refinements.
