java - Transfer object parameters between controllers -

i have 2 methods inside controller:

@controller @requestmapping("/feed") public class feedbackcontroller extends baseaccountcontroller {  @requestmapping("/reply")         public modelandview replymsg(feedback temp,modelmap modelmap,httpservletrequest request,httpservletresponse response) {         ................            feedback fb = new feedback();         fb.setproductid(temp.getproductid());         view.setviewname("redirect:/feed/list.do");         view.addobject("feedback",fb);         return view;     }      @requestmapping("/list")         public string list(feedback feedback, modelmap map, httpservletrequest request) {     ......     integer productid = feedback.getproductid();//check if feedback object transferred     return "/feedback/list"; // .jsp or .ftl file.     }  } 

feedback simple java bean.i want transfer object replymsg() list().

but result is: yes,the functioin forwarded list(), feedback.getproductid().it means list() doesn't feedback object replymsg();

after change view.setviewname("redirect:/feed/list.do"); view.setviewname("forward:/feed/list.do"); , doesn't work.

so , tell me can do? new java front end;
