Java : org.mise en veille prolongée.PropertyAccessException tout en appelant setter et getter

Je suis la construction d'une application en java à l'aide de restlet et Hibernate .

J'ai de l'utilisateur de l'entité de la classe et à chaque fois que je demande http get .
J'obtiens l'erreur .

{
    "error": "20000:Hibernate Exception. : org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of tecd.persistence.entity.User.idUser",
    "status": 500
}

Voici ma classe d'entité .

Veuillez me suggérer quel est le problème ici .Est-il une version de java problème ou ce que je ne suis pas en mesure de comprendre ce problème .

Table Mysql ressemble

CREATE TABLE `user` (
`idUser` int(11) NOT NULL AUTO_INCREMENT,
