Success =success;  This. msg =msg; }     PublicResult (Booleansuccess, T data) {        Super();  This. Success =success;  This. data =data; }}

This class provides great convenience for both front-and back-table interactions:

Here is the Ajax interaction in front of the background:

Front Office Ajax Code:

 $.ajax ({url:  "<%=request.getcontextpath ()%>/supp/deletesupp" , data: {Supplierid:supplierid}, Async:  false , //  If the request is asynchronous, the default is async, which is also an important AJAX feature  type: "GET", //  request method  success: function   var  rs = eval (' (' +data+ ') ' );                Flag  = rs.success;  if  " Delete succeeded!)                "); }            }        });

Here is the background Java code:

    @RequestMapping ("/deletesupp")    @ResponseBody    public result<string>  Deletesupplier (HttpServletRequest request) {        Resultnew result<>();         = Request.getparameter ("supplierId");        Supplierservice.deletesupplierbyid (supplierId);        Rs.setsuccess (true);         return rs;    }
