Multi upload Ajax et Spring MVC
Bonjour,
Je voudrais faire du multi upload avec une requete ajax (prototype) et Spring MVC.
Voici mon code :
Du côté de la JSP :
Code:

function ajaxRequest() {
...
if (formValide == true)
{
$('formulaire').request({
method: 'post',
enctype: 'multipart/form-data',
onCreate: function(response) {
startLoading();
},
onSuccess: function(response) {
...
stopLoading();
},
onFailure: function(response) {alert("il y eu un probleme");}
});
return false;
}
else
{
return false;
}
} |
La fonction startLoading lance une wait bar.
La fonction ajaxRequest est appelée lors du onsubmit du formulaire.
Du côté de la classe Java :

...
MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
final Map<String, MultipartFile> files = multiRequest.getFileMap();
mLog.debug("no of files:"+files.size());
try {
if (files == null) {
mLog.debug("no file was sent");
}
else{
Iterator<MultipartFile> fileIterator=files.values().iterator();
MultipartFile file;
while(fileIterator.hasNext()) {
File saveFile = new File(session.getServletContext().getRealPath("/")
+"uploadedFiles/"));
saveFile.mkdirs();
file =(MultipartFile)fileIterator.next();
File destination = new File(saveFile+ "/" + file.getOriginalFilename());
if(destination.createNewFile()) {
mLog.debug("file name:"+file.getOriginalFilename());
file.transferTo(destination);
//make an entry if the transfer succeeds
}
}
}
} catch (Exception e) {
e.printStackTrace();
} |
Et quand je soumets mon formulaire j'ai cette erreur :
