The code looks fine. Reading your question, it seems that you might be a little confused between these two:

Hibernate ORM: Implementation of JPA

Hibernate Validator: Implementation of Bean Validation

So, for Bean Validation to work, you need to add Hibernate Validator in classpath. Means simply add it in dependencies of your build.gradle/pom.xml i.e. the build script of your build tool.

@ZeeshanMemon: Your code seems okay. Please check if the jar files that you added have been added properly. – Minar Mahmud Jun 13 '18 at 15:13
