I have a servlet that will handle few hundread thousand requests per day. I
am using the commons FileUpload to loop thru the fields and file items.
Here is the code
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
try {
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List<FileItem> items = upload.parseRequest(req);
for (FileItem item : items) {
....
}
}
catch (Exception e) {
...
}
}
Since the servlet is being called so many times, can I make the
DiskFileItemFactory global static so it won't create the factory object so
many times? In sum, is DiskFileItemFactory class thread safe?
DiskFileItemFactory factory = new DiskFileItemFactory();
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
try {
ServletFileUpload upload = new ServletFileUpload(factory);
List<FileItem> items = upload.parseRequest(req);
for (FileItem item : items) {
....
}
}
catch (Exception e) {
...
}
}
Thanks!
