fastjson 错误解决方案详情 com.alibaba.fastjson.JSONException: syntax error, expect {, actual EOF, pos 1410

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:

 /**
      *
      * <p>
      * <p>添加订单
      *
      * @return Object
      */
     @ResponseBody
     @RequestMapping(value = "/addOrder", //
             method = RequestMethod.POST)
     public Object addOrder(@RequestBody BaseSingleList baseSingleList) {

         return orderService.addOrder(baseSingleList);

  }

前端发送json样式

 {
     "singleOrderList":[
         {
             "orderName":"唐1",
             "orderPhone":"13245124512",
             "contact":"送",

                     "modularNum":3
                 }
             ]
         },
         {
             "orderName":"唐1",
             "orderPhone":"13245124512",
             "contact":"送",

                     "modularNum":3
                 }
             ]
         }
     ]
 }

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

 /**
      * 下订单
      *
      * @param baseSingleList
      * @return Object
      */
     @Override
     public Object addOrder(BaseSingleList baseSingleList) {

         String lineArray = JSONArray.toJSONString(baseSingleList);
         HashMap parseMap = JSON.parseObject(lineArray,HashMap.class);

         List<SingleOrder> singleOrderList = JSON.parseArray(JSON.parseObject(lineArray).getString("singleOrderList"),SingleOrder.class);

          for(SingleOrder singleOrder : singleOrderList){

              System.out.println(singleOrder.getUserId());
          }
 }

(2)当数据传入是Map时

 /**
      * 下订单
      *
      * @param baseSingleList
      * @return Object
      */
     @Override
     public Object addOrder(BaseSingleList baseSingleList) {

         Map<String, Object> map = new HashMap<String, Object>();
         map.put("count", 2);
         map.put("studentList", baseSingleList);
         String json = JSON.toJSONString(map, true);

         HashMap parseMap = JSON.parseObject(json, HashMap.class);
         List<BaseSingleList> studentList1 = (List<BaseSingleList>) parseMap.get("baseSingleList");

          for (SingleOrder singleOrder : singleOrderList) {

             System.out.println(singleOrder.getUserId());
   }

 }
