这个Controller控制器怎么写_course

/** * 费用管理修改 * @throws Exception */ @ResponseBody @RequestMapping(value="/updateCharingCost") public boolean updateCharingCost(ChargingCost chargingCost) throws Exception { User usr = (User) this.getSession().getAttribute(Const.SESSION_USER); String usrID = usr.getUserID(); boolean bool=false; bool=chargingCostService.update(chargingCost, usrID); return bool; } /** * 费用管理删除 * @throws Exception */ @ResponseBody @RequestMapping(value="/deleteCharingCost") public boolean deleteChargingCost(ChargingCost chargingCost) throws Exception{ User usr = (User) this.getSession().getAttribute(Const.SESSION_USER); String usrID = usr.getUserID(); boolean bool=chargingCostService.delete(chargingCost, usrID); return bool; } } 这个是Controller，， public boolean update(ChargingCost chargingCost, String usrID) throws Exception { boolean bool = false; Date date = Tools.getNowtimeTwo(); chargingCost.setUpdateUser(usrID); chargingCost.setUpdateDTTM(date); int ExecuteCnt = (int) this.getDaoSupport().update("ChargingCost.update", chargingCost); if (ExecuteCnt > 0) { bool = true; } return bool; } /** * 删除费用 */ public boolean delete(ChargingCost chargingCost, String usrID) throws Exception { boolean bool = false; Date date = Tools.getNowtimeTwo(); chargingCost.setDeleteFlag(0); chargingCost.setUpdateUser(usrID); chargingCost.setUpdateDTTM(date); int ExecuteCnt = (int) this.getDaoSupport().update("ChargingCost.delete", chargingCost); if (ExecuteCnt > 0) { bool = true; } return bool; } 这个是service， function update_Cost() { var len = document.getElementsByName("chk").length; var selectCount = 0; // 判断是否一个未选 for (var i = 0; i < len; i++) { if (document.getElementsByName("chk")[i].checked == true) { selectCount = selectCount + 1; userData.push(i + 1); s=i+1; } } if (selectCount == 1) { $('#costInformationUpdate').modal('show'); // 设置弹出窗口的位置 var model=document.getElementById("costInformationUpdate"); var tb = document.getElementById("costTable"); var tr = tb.rows[s]; $("#updateChargingStationName").val(tr.cells[2].innerText); $("#updateEffectiveDate").val(tr.cells[3].innerText); } else if (selectCount == 0) { showMessge("请选择要操作的数据!","model1"); } else { showMessge("抱歉,不能选择多行!","model1"); } } //确认修改 function updateChargingCost(){ var updateChargePrice=$("#updateChargePrice").val(); var updateServicePrice=$("#updateServicePrice").val(); var updateMonthKWH=$("#updateMonthKWH").val(); $.ajax({ type: "POST", url: 'updateCharingCost', data: { ChargePrice:updateChargePrice, ServicePrice:updateServicePrice, MonthKWH:updateMonthKWH, }, dataType:'json', success : function(data) { if (data) { showMessge("修改成功!","model1"); $('#update').modal('hide'); saveCharingCost(); } else { showMessge("修改失败!","model1"); $('#update').modal('hide'); } }, error : function(data) { if (data.status == "403" && data.statusText == "Forbidden") { showMessge("您没有操作权限!","model1"); } else { showMessge("操作失败!","model1"); } } }); } 这个是js，，但是date一直是false，觉得是控制器写错了，，大神告诉我怎么写吧，没有一点思路
