Java Spring MVC How to get this set value? -


how value has been set method? how pass value post method? should declare global variable?

edit: want doing on method , display textbox on jsp if setdisplaybox = true. when user post form, setdisplaybox should true , return same jsp without redirect

@requestmapping(method = requestmethod.get) public string getsuccess(modelmap model, @modelattribute("user") user user, httpservletrequest request) {     string boxdisplay = "true";      user.setdisplaybox(boxdisplay);     return "success"; }  @requestmapping(method = requestmethod.post) public string resetpassword(httpservletrequest request, modelmap model, @modelattribute("user") user user, modelmap modelmap)  {     user.setdisplaybox(user.getdisplaybox()); //how value has been set above?     return "success"; }

set global variable user.

private user useraccount;  @requestmapping(method = requestmethod.get) public string getsuccess(modelmap model, @modelattribute("user") user user, httpservletrequest request) {     string boxdisplay = "true";      user.setdisplaybox(boxdisplay);     useraccount = user; //load user in global var      return "success"; }  @requestmapping(method = requestmethod.post) public string resetpassword(httpservletrequest request, modelmap model, @modelattribute("user") user user, modelmap modelmap)  {     user.setdisplaybox(useraccount.getdisplaybox());      useraccount = null; //reset make sure loading user later.     return "success"; }
