12.6 Applying Validation to Other Classes

12.6 Applying Validation to Other Classes
Domain classes and Command Objects support validation by default. Other classes may be made validateable by defining the static constraints
property in the class (as described above) and then telling the framework about them. It is important that the application register the validateable classes with the framework. Simply defining the constraints
property is not sufficient.
The Validateable Trait
Classes which define the static constraints
property and implement the Validateable trait will be validateable. Consider this example:
src/main/groovy/com/mycompany/myapp/User.groovy
