Java.lang.IllegalStateException: Aucun unmarshaller enregistré. Vérifiez la configuration de WebServiceTemplate

Lorsque j'envoie une demande SOAP au serveur, elle renvoie l'erreur suivante. Je ne sais pas comment je peux configurer unmarshaller, je vais envoyer des demandes SOAP à plusieurs webservices. WSDL est ici.

J'ai visité les pages suivantes mais je n'ai pas encore trouvé de solution. 1,2,3

 java.lang.IllegalStateException: No unmarshaller registered. Check configuration of WebServiceTemplate.
