In this setup, the presence of a single parameterized constructor implies that constructor binding should be used.
This means that the binder will find a constructor with the parameters that you wish to have bound.
If your class has multiple constructors, the `@ConstructorBinding` annotation can be used to specify which constructor to use for constructor binding.
To opt out of constructor binding for a class with a single parameterized constructor, the constructor must be annotated with `@Autowired`.
To opt out of constructor binding for a class with a single parameterized constructor, the constructor must be annotated with `@Autowired` or made `private`.
Constructor binding can be used with records.
Unless your record has multiple constructors, there is no need to use `@ConstructorBinding`.
