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

缘由:

      前端传递的数组过于复杂,却是出现这种问题,前端采用vue axios,发送请求,后端java接收代码,实现先后端分离

后端就收fastjson接收json,进行业务处理,后端Controller情况:

 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":3

解决方案:

       controller正常传入数据,在serviceImpl层中对数据进行分解和从新发送业务逻辑:

    (1)当数据传入是JsonObject,用以下方法传递

 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 }
