La demande en cours n'est pas une demande en plusieurs parties - Spring MVC
- Spring 3.1.1.LELEASE
- Jetée 7.3.0.v20110203
- commons-fileupload 1.2.1
- commons-io 1.4
Je souhaite télécharger deux fichiers au format HTML, mais je reçois toujours une exception de requête en plusieurs parties. J'ai beaucoup cherché sur Google mais je n'ai pas trouvé la bonne solution.

Essayez d'ajouter les en-têtes:
@RequestMapping(value=("/uploadpsd"),headers=("content-type=multipart/*"),method=RequestMethod.POST)
Vous devez ajouter ceci à votre printemps xml
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
</bean>
Assurez-vous que vous utilisez les guillemets corrects pour l'attribut enctype- de l'élément form- dans votre jsp.
1 .enctype=”multipart/form-data”
2 .enctype="multipart/form-data"
observez les guillemets doubles ici il y a une différence entre les deux ... utilisez enctype="multipart/form-data" que enctype=”multipart/form-data”
