Dynamic Properties Beans

This project demonstrates a method of loading configuration properties into objects and making them available on the application context. Similar to the use of a class annotated with @ConfigurationProperties, properties with a specific prefix are bound to an object. However, in this case, a key-value map is processed in such a way that each value is bound to an object and provided as a bean on the application context with its key as bean name.

The effect is demonstrated by mapping the following application.yaml:

my.properties:
  foo:
    name: Foo
    value: 15
  bar:
    name: Baz
    value: 50

This results in two CustomProperties beans being available on the application context, with the names "foo" and "bar", respectively.
