我遇到MultiUploader()对象上传文件的问题。一切都很好但是当文件有空格时,上传者停止了他的工作。有人可以帮忙吗?
我的servlet文件上传:
public class MultimediaUpload extends UploadAction {
private static final long serialVersionUID = 1L;
Hashtable<String, String> receivedContentTypes = new Hashtable<String, String>();
/**
* Maintain a list with received files and their content types.
*/
Hashtable<String, File> receivedFiles = new Hashtable<String, File>();
/**
* Override executeAction to save the received files in a custom place and
* delete this items from session.
*/
@Override
public String executeAction(HttpServletRequest request, List<FileItem> sessionFiles) throws UploadActionException {
String response = "";
for (FileItem item : sessionFiles) {
if (false == item.isFormField()) {
try {
String path = System.getProperty("catalina.home") + System.getProperty("file.separator") + "webapps" + System.getProperty("file.separator") + "data"
+ System.getProperty("file.separator") + "images" + System.getProperty("file.separator");
String tip = item.getName().substring(item.getName().lastIndexOf("."));
File file = new File(path + new Date().getTime() + tip);
item.write(file);
// / Save a list with the received files
receivedFiles.put(item.getFieldName(), file);
receivedContentTypes.put(item.getFieldName(), item.getContentType());
// / Send a customized message to the client.
response += file.getName();
} catch (Exception e) {
throw new UploadActionException(e);
}
}
}
// / Remove files from session because we have a copy of them
removeSessionFileItems(request);
// / Send your customized message to the client
return response;
}
/**
* Get the content of an uploaded file.
*/
@Override
public void getUploadedFile(HttpServletRequest request, HttpServletResponse response) throws IOException {
String fieldName = request.getParameter(UConsts.PARAM_SHOW);
File f = receivedFiles.get(fieldName);
if (f != null) {
response.setContentType(receivedContentTypes.get(fieldName));
FileInputStream is = new FileInputStream(f);
copyFromInputStreamToOutputStream(is, response.getOutputStream());
} else {
renderXmlResponse(request, response, XML_ERROR_ITEM_NOT_FOUND);
}
}
/**
* Remove a file when the user sends a delete request.
*/
@Override
public void removeItem(HttpServletRequest request, String fieldName) throws UploadActionException {
File file = receivedFiles.get(fieldName);
receivedFiles.remove(fieldName);
receivedContentTypes.remove(fieldName);
if (file != null) {
file.delete();
}
}
}
我的客户方:
MultiUploader defaultUploader = MultiUploader();
defaultUploader.setHeight("200");
defaultUploader.setValidExtensions(".jpg", ".png", ".gif");
我将此添加到我的面板中。
