and then I want to convert SpringMvc form I have created a controller code DEBUG a moment everything is normal I found List items = upload.parseRequest (request); as empty who encountered to help solve this problem

first post formats perhaps not consistent with the public viewing habits have also requested exhibitions
------ Solution ------------- -------------------------------
does not solve this problem I have encountered this problem lz ah
------ Solution ------------------------------------------ -
this problem , generally because of InputStream has been struts2 to read ahead over ( because it wants to help you check whether there is the need to deal with VO value object class )
So after studying less things.
processing method, see here :
http://auzll.iteye.com/blog/919981
------ Solution ------------------------------------ --------
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
upload.setHeaderEncoding("UTF-8");
List items;
try {
items = upload.parseRequest(request);
.....................
This factory is just new out, so upload it just an empty object , upload.parseRequest (request) should be empty, no problem.
landlord here upload objects should not be so established fishes .
------ Solution ---------------------------------------- ----
used springmvc
------ For reference only ------------------------ ---------------
no one is using the text editor indeditor what nobody uses SpringMvc what the answer is yes too Furthermore, there are many but the two combined together again so small it was a day are no buyers ah
------ For reference only ----------- ----------------------------
3 floor, I use springmvc just three months into the line has not been used struts2 I feel the 4th floor is a positive solution I try
------ For reference only ---------------------- -----------------
4 F, I learned a long time does not help you write about the
------ For reference only - -------------------------------------
did not solve ah honed too many things are copying and pasting it really was so engaged in strenuous ah
------ For reference only -------------------- -------------------
to use jsp can also be used inside the springmvc
------ For reference only ----- ----------------------------------
why the same code written in a servlet is no problem , However, when it replaced spingMVC problems mentioned above .
how to solve ?
------ For reference only -------------------------------------- -
expect answers
------ For reference only -------------------------------- -------
encountered the same problem ?
------ For reference only ------------------------------------ ---
expect answers .....
------ For reference only --------------------- ------------------
answer where someone knows no
------ For reference only --------- ------------------------------
rub , the landlord did not solve ? Today, I used to use struts good today with springMVC encountered the same problem you , Guiqiu answer
That is a really gold tip particularly to those fresh to the blogosphere.
