==== @DefaultValue and Binding
Default values can be specified using javadoc:org.springframework.boot.context.properties.bind.DefaultValue[format=annotation] on constructor parameters and record components.
The conversion service will be applied to coerce the annotation's javadoc:java.lang.String[] value to the target type of a missing property.
Property placeholders in the annotation's javadoc:java.lang.String[] value are replaced and the conversion service is applied to coerce it to the target type of a missing property.
In the `MyProperties` example above, you can see the nested `Security` class uses `@DefaultValue("USER")` for the `roles` parameter.
This means that if `security` properties are defined, but `roles` is not, the default of `"USER"` will be bound.
