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

Posted 2020-11-01 北极的大企鹅

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",

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 }
