It has taken me a little while, but I do like the hierarchical look of the properties described in a yaml format. So now, given this property file a traditional Spring application would have loaded up the properties the following way public class Sample. Property. Loading. Test. Valueprefix. Prop. 1. private String string. Prop. 1. Note the placeholder for prefix. Prop key. This however is not ideal for loading a family of related properties, say in this specific case namespaced by the prefix conveniently named prefix. The approach Spring boot takes is to define a bean that can hold all the family of related properties this way Configuration. Propertiesprefix prefix. Sample. Property. String string. Prop. String string. Prop. Integer int. Prop. Listlt String list. Prop. private Maplt String, String map. Prop. At runtime, all the fields would be bound to the related properties cleanly.

Properties will call the validator to ensure that bound bean is validated. An integration test making use of this is the following package prop. Test. import org. Run. With. import org.
