我试图自定义Liferay Web Form portlet来接受文件上传，并且除了将文件附加到要发送的电子邮件之外，我几乎可以完成所有工作。commons-fileupload和Liferay的问题
从表单中获取字段：
public void saveData(ActionRequest actionRequest, ActionResponse actionResponse) {
...
File uploadedFile = null;
...
Map<String,String> fieldsMap = new LinkedHashMap<String,String>();
// Create a FileItemFactory for disk-based file items
DiskFileItemFactory factory = new DiskFileItemFactory(1073741824, new File("/temp"));
// Create a new file upload handler
PortletFileUpload upload = new PortletFileUpload(factory);
upload.setSizeMax(67108864);
// Parse the request
List<FileItem> items = upload.parseRequest(actionRequest);
int i = 1;
Iterator iter = items.iterator();
// Throw away the hidden field, don't need it
FileItem dud = (FileItem)iter.next();
while (iter.hasNext()) {
FileItem item = (FileItem)iter.next();
String fieldLabel = preferences.getValue(
"fieldLabel" + i, StringPool.BLANK);
String fieldType = preferences.getValue(
"fieldType" + i, StringPool.BLANK);
if (Validator.isNull(fieldLabel)) {
break;
}
if(!fieldType.equals("file")) {
String fieldValue = item.getString();
fieldsMap.put(fieldLabel, fieldValue);
} else {
String fieldName = item.getName();
uploadedFile = new File(fieldName);
item.write(uploadedFile);
}
i++;
}
...
if(sendAsEmail) {
emailSuccess = sendEmail(fieldsMap, preferences, uploadedFile);
}
}
然后建设和电子邮件的发送：
protected boolean sendEmail(Map<String, String> fieldsMap, PortletPreferences preferences, File uploadedFile) {
MailMessage mailMessage = new MailMessage(fromAddress, toAddress, subject, body, false);
if(uploadedFile != null) { // i.e., there was 'file' field up above
mailMessage.addAttachment(uploadedFile);
}
MailServiceUtil.sendEmail(mailMessage);
if(uploadedFile != null) {
uploadedFile.delete();
}
}
我得到试图处理文件上传，并附上时，下面的控制台错误文件到邮件：
16:09:49,597 ERROR [MailEngine:489] IOException while sending message
16:09:49,598 ERROR [MailEngine:154] java.io.FileNotFoundException: helpdesk_.png (No such file or directory)
我有我的DiskFileItemFactory配置是否正确？我可能做错了什么？
谢谢。
