Overview
Spring supports Bean Validation API (JSR-303) which allows to declare validation rules as annotations, as opposed to explicitly writing validation logic in the application code. The Bean Validation API and the Hibernate implementation of the Validation API are automatically added to the project as transient dependencies of the Spring Boot web starter.
Bean Validation in Spring MVC
Applying bean validation in Spring MVC consists of:
Declare Validation Rules

Configure Controller Methods for which Validation Should Be Performed
Designate controller methods for which validation should be performed.
Configure Forms to Display Validation Errors
