JSP：

<script type="text/javascript">
$(document).ready(function() {
    $('#UserRegistration').jtable({
        title : 'User Registration',
        paging: false, //Enable paging
        //pageSize: 3, //Set page size (default: 10)           
        actions : {
            listAction: 'Controller?action=list',
           // createAction:'Controller?action=create',
            updateAction: 'Controller?action=update',
            deleteAction: 'Controller?action=delete'                      
  },
        fields : {
            UserId : {
                title : 'UserId Id',
                //sort :true,
                //width : '30%'             
            },
            FirstName : {
                title : 'FirstName',
                //width : '30%',
                edit : true
            },

            LastName : {
                title : 'LastName',
                //width : '30%',
                edit : true
            },
            MiddleName : {
                title : 'MiddleName',
                //width : '30%',
                edit : true
            },

            EmailID : {
                title : 'EmailID',
                //width : '30%',
                edit : true
            },
            Role : {
                title : 'Role',
                //width : '20%',
                edit : true
            },
            EmployeeId:{
                title:'Employee Id',
                //width:'20%',
                edit:true

            }
        }

    });
    $('#UserRegistration').jtable('load');
});
</script>

遵循控制器列表方法

String action = request.getParameter("action");
        List<UserRegistration> UsertList = new ArrayList<UserRegistration>();
        Gson gson = new GsonBuilder().setPrettyPrinting().create();
        //String jsonArray = gson.toJson(JSONROOT);
        response.setContentType("application/json");
        HashMap<String, Object> JSONROOT = new HashMap<String, Object>();
        if(action.equals("list")){
            try{                        
                //Fetch Data from User Table
                UsertList=dao.getAllUsers();
                //Return in the format required by jTable plugin
                JSONROOT.put("Result", "OK");
                JSONROOT.put("Records", UsertList);
             // Convert Java Object to Json
                String jsonArray = gson.toJson(JSONROOT);
                System.out.println(jsonArray);
                response.getWriter().print(jsonArray);

                }catch(Exception ex){
                     JSONROOT.put("Result", "ERROR");
                     JSONROOT.put("Message", ex.getMessage());
                     String error = gson.toJson(JSONROOT);
                     response.getWriter().print(error);
                }
        }
