La demande actuelle n'est pas un multipart demande - Spring MVC

• Printemps 3.1.1.COMMUNIQUÉ de
• Jetée 7.3.0.v20110203

• commons-io 1.4

Je veux le télécharger deux fichiers par formulaire html, mais je reçois toujours un multipart demande d'exception.
J'ai googlé beaucoup, mais n'a pas trouvé la bonne solution.
