[align=right][align=left]DiskFileItemFactory factory=new DiskFileItemFactory();

String path=request.getRealPath("/upload");
System.out.println(path);
factory.setRepository(new File(path));

factory.setSizeThreshold(1024*1024);

ServletFileUpload upload=new ServletFileUpload(factory);

try{
List<FileItem> ls=upload.parseRequest(request);

for (FileItem item : ls) {
if(item.isFormField()){
String name=item.getFieldName();

String value=item.getString("gbk");

request.setAttribute(name, value);
}else{

String name=item.getFieldName();

String value=item.getName();

int start=value.lastIndexOf("\\");

String fileName=value.substring(start+1);
System.out.println(fileName);
request.setAttribute(name, fileName);
Encoding en=new Encoding();

//item.write(new File(path,fileName));
OutputStream os=new FileOutputStream(new File(path,fileName));

InputStream is=item.getInputStream();

byte [] bt=new byte[400];

int length=0;

while((length=is.read(bt))>0){
os.write(bt, 0, length);
}

os.close();

is.close();
}
}
}catch (Exception e) {
e.printStackTrace();
