Nested members of a `@ConstructorBinding` class (such as `Security` in the example above) will also be bound through their constructor.
Default values can be specified using `@DefaultValue` and the same conversion service will be applied to coerce the `String` value to the target type of a missing property.
By default, if no properties are bound to `Security`, the `MyProperties` instance will contain a `null` value for `security`.
Default values can be specified using `@DefaultValue` on a constructor parameter or, when using Java 16 or later, a record component.
The conversion service will be applied to coerce the `String` value to the target type of a missing property.
Referring to the previous example, if no properties are bound to `Security`, the `MyProperties` instance will contain a `null` value for `security`.
If you wish you return a non-null instance of `Security` even when no properties are bound to it, you can use an empty `@DefaultValue` annotation to do so:
