11.6.3. Validation Constraints
11.6.3.1. About Validation Constraints
Validation constraints are rules applied to a java element, such as a field, property or bean. A constraint will usually have a set of attributes used to set its limits. There are predefined constraints, and custom ones can be created. Each constraint is expressed in the form of an annotation.
The built-in validation constraints for Hibernate Validator are listed here: Section 11.6.3.4, “Hibernate Validator Constraints”
For more information, refer to Section 11.6.2, “Hibernate Validator” and Section 11.6.1, “About Bean Validation”.
