File tmp = new File("/upload/voice/",multipartFile.getOriginalFilename());
if(!tmp.exists()){
tmp.getParentFile().mkdirs();
tmp.createNewFile();
}
multipartFile.transferTo(tmp);这是上传的代码,我再root下面也建了/upload/voice/文件夹,可是上传成功了里面却没有文件,怎样让文件能传到在root下/upload/voice/??????求解.....

这个multipartFile并没有上传到你的服务器的文件夹上,要上传你还少做了点东西,看看这个//得到文件?名
String filename=file.getOriginalFilename();
25.
if(file.getSize()>0){
try {
SaveFileFromInputStream(file.getInputStream(),"D:/",filename);
} catch (IOException e) {
System.out.println(e.getMessage());
return null;
}
}else{
throw new Exception("上传失败:上传文件不能为?空");
}
public void SaveFileFromInputStream(InputStream stream,String path,String filename) throws IOException {
FileOutputStream fs=new FileOutputStream( path + "/"+ filename);
byte[] buffer =new byte[1024*1024];
int bytesum = 0;
int byteread = 0;
while ((byteread=stream.read(buffer))!=-1){
bytesum+=byteread;
fs.write(buffer,0,byteread);
fs.flush();
}
fs.close();
stream.close();
}
改改就可以用了
