原因:
前端传递的数组过于复杂,倒是出现这种问题,前端采用vue axios,发送请求,后端java接收代码,实现前后端分离
后端就收fastjson接收json,进行业务处理,后端Controller状况:
1 /** 2 ?????* ?3 ?????* <p> 4 ?????* <p>添加订单 5 ?????* 6 ?????* @return Object 7 ?????*/ 8 ????@ResponseBody 9 ????@RequestMapping(value = "/addOrder", //10 ????????????method = RequestMethod.POST)11 ????public Object addOrder(@RequestBody BaseSingleList baseSingleList) {12 13 ????????return orderService.addOrder(baseSingleList);14 15 ?}前端发送json样式
1 { 2 ????"singleOrderList":[ 3 ????????{ 4 ????????????"orderName":"唐1", 5 ????????????"orderPhone":"13245124512", 6 ????????????"contact":"送", 7 ????????????"telephony":"7845120231111", 8 ????????????"provinceId":31, 9 ????????????"cityId":3101,10 ????????????"regionId":310108,11 ????????????"address":"默认添加唐",12 ????????????"userId":"c6f53705451b497580ef093c0ff5",13 ????????????"serieId":"1",14 ????????????"trueTime":"2018-04-27",15 ????????????"overTime":"2019-04-27",16 ????????????"monthlyRent":6000,17 ????????????"dateCount":12,18 ????????????"packageId":"3e449fb4b4a489fce1475c4577fb6",19 ????????????"applicationArea":"ssswww",20 ????????????"total":"219000",21 ????????????"ModularIdNum":[22 ????????????????{23 ????????????????????"itemId":"9b744dc99e2904d96ab1af5",24 ????????????????????"modularNum":325 ????????????????}26 ????????????]27 ????????},28 ????????{29 ????????????"orderName":"唐1",30 ????????????"orderPhone":"13245124512",31 ????????????"contact":"送",32 ????????????"telephony":"7845120231111",33 ????????????"provinceId":31,34 ????????????"cityId":3101,35 ????????????"regionId":310108,36 ????????????"address":"默认添加唐",37 ????????????"userId":"b4f13b97580ef093c0ff5",38 ????????????"serieId":"1",39 ????????????"trueTime":"2018-04-27",40 ????????????"overTime":"2019-04-27",41 ????????????"monthlyRent":6000,42 ????????????"dateCount":12,43 ????????????"packageId":"3b4b4a489fce1475c4577fb6",44 ????????????"applicationArea":"ssswww",45 ????????????"total":"219000",46 ????????????"ModularIdNum":[47 ????????????????{48 ????????????????????"itemId":"09932da9b744dc99e295",49 ????????????????????"modularNum":350 ????????????????}51 ????????????]52 ????????}53 ????]54 }解决方案:
controller正常传入数据,在serviceImpl层中对数据进行分解和重新发送业务逻辑:
(1)当数据传入是JsonObject,用如下方法传递
1 /** 2 ?????* 下订单 3 ?????* 4 ?????* @param baseSingleList 5 ?????* @return Object 6 ?????*/ 7 ????@Override 8 ????public Object addOrder(BaseSingleList baseSingleList) { 9 10 ????????String lineArray = JSONArray.toJSONString(baseSingleList);11 ????????HashMap parseMap = JSON.parseObject(lineArray,HashMap.class);12 13 ????????List<SingleOrder> singleOrderList = JSON.parseArray(JSON.parseObject(lineArray).getString("singleOrderList"),SingleOrder.class);14 ????????15 ?????????for(SingleOrder singleOrder : singleOrderList){16 17 ?????????????System.out.println(singleOrder.getUserId());18 ?????????}19 }(2)当数据传入是Map时
1 /** 2 ?????* 下订单 3 ?????* 4 ?????* @param baseSingleList 5 ?????* @return Object 6 ?????*/ 7 ????@Override 8 ????public Object addOrder(BaseSingleList baseSingleList) { 9 10 11 12 ????????Map<String, Object> map = new HashMap<String, Object>();13 ????????map.put("count", 2);14 ????????map.put("studentList", baseSingleList);15 ????????String json = JSON.toJSONString(map, true);16 17 18 ????????HashMap parseMap = JSON.parseObject(json, HashMap.class);19 ????????List<BaseSingleList> studentList1 = (List<BaseSingleList>) parseMap.get("baseSingleList");20 21 ?????????for (SingleOrder singleOrder : singleOrderList) {22 ??????????23 ????????????System.out.println(singleOrder.getUserId());24 ??}25 26 }
