fastjson 錯誤解決方案詳情 com.alibaba.fastjson.JSONException: syntax error, expect {, actual EOF, pos 1410

緣由:

      前端傳遞的數組過於複雜,卻是出現這種問題,前端採用vue axios,發送請求,後端java接收代碼,實現先後端分離

後端就收fastjson接收json,進行業務處理,後端Controller情況:

 1 /**
 2      * 
 3      * <p>
 4      * <p>添加訂單
 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  }

前端發送json樣式

 3         {

解決方案:

       controller正常傳入數據,在serviceImpl層中對數據進行分解和從新發送業務邏輯:

    (1)當數據傳入是JsonObject,用以下方法傳遞

 1 /**
 2      * 下訂單
 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)當數據傳入是Map時

 1 /**
 2      * 下訂單
 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 }
