@RequestMapping

public
void
doTmallGujia(String callbackUrl, HttpServletResponse response,HttpServletRequest request){
try
{
request.getSession();
if
(StringUtils.isNotBlank(callbackUrl)){
callbackUrl = URLDecoder.decode(callbackUrl,
"UTF-8"
);
response.sendRedirect(callbackUrl);
}
}
catch
(IOException e) {
LOGGER.error(
