form表单数据封装成json格式并提交给服务器的实现方法

1、jsp代码，form表单：

2、js代码：

$(".fee_sure").click(function () {
  var dataObj = $("#costForm").serialize();
  var payType = $('input[name="payType"]:checked').val();
  if(payType == undefined){
   alert("请选择付款类型");
   return ;
  }else{
   $.ajax({
    url:"/webCenter.do?method=saveUserMessage",
    type: "post", 
    dataType:"json",
    data:dataObj,
    cache:false,
    ifModified:true,
    success:function(json){
      if(json.flag == 1){
alert("1234");
      }
    }
   })
  }
 })

3、后台action处理：

@RequestMapping(params ="method=saveUserMessage",method=RequestMethod.POST)  //导入发言
     public void saveUserMessage(int userId,HttpServletRequest request,HttpServletResponse response){
      try {
HttpSession session = this.getSession(request);
Adminuser adminUser = session.getAttribute("centerAdminUser") == null?null:(Adminuser) session.getAttribute("centerAdminUser");
if(adminUser == null){
 try {
  response.sendRedirect(request.getContextPath()+"/center/index.jsp");
 } catch (Exception e) {
  e.printStackTrace();
 }
}else{
 String billNumber = request.getParameter("billCode")==null?"":request.getParameter("billCode");
 String isBaodao = request.getParameter("baodao")==null?"0":request.getParameter("baodao");
 String haspay = request.getParameter("pay")==null?"0":request.getParameter("pay");
 String payType = request.getParameter("payType")==null?"0":request.getParameter("payType");
 String isFkpz = request.getParameter("isReceiveProof")==null?"0":request.getParameter("isReceiveProof");
 String isYkfp = request.getParameter("isBill")==null?"0":request.getParameter("isBill");
 String isYlfp = request.getParameter("isDrawBill")==null?"0":request.getParameter("isDrawBill");
 JSonObject jsonObject = new JSonObject();
 //AdminuserConferences adminuserConferences = webService.getAdminuserConferences(adminUser.getAdminuserId());
 UserInfo userInfo = webService.getUserInfoById(userId);
 if(userInfo!=null)
 {
  jsonObject.accumulate("flag",1);
  ChcRegUser chcRegUser = webService.getChcRegUser(userId);
  if(chcRegUser!=null)
  {
   chcRegUser.setHasPay(Integer.parseInt(haspay));
   chcRegUser.setPayType(Integer.parseInt(payType));
   if(chcRegUser.getHasPay()-chcRegUser.getPay()==0)
   {
    chcRegUser.setStateType(1);
   }
   webService.saveObject(chcRegUser);
   userInfo.setIsBaodao(Integer.parseInt(isBaodao));
   userInfo.setIsFkpz(Integer.parseInt(isFkpz));
   userInfo.setBillNumber(billNumber);
   userInfo.setIsYlfp(Integer.parseInt(isYlfp));
   userInfo.setIsYkfp(Integer.parseInt(isYkfp));
   webService.saveObject(userInfo);
   jsonObject.accumulate("pay", chcRegUser.getPay());
   jsonObject.accumulate("haspay", chcRegUser.getHasPay());
  }
 }else {
  jsonObject.accumulate("flag",0);
 }
 writeJson(response, jsonObject.toString());
}
      } catch (Exception e) {
e.printStackTrace();
      }
     }
