Fastjson Error Solution details Com.alibaba.fastjson.JSONException:syntax error, expect {, actual EOF, POS 1410

Reason:

The array passed by the front end is too complex, but this problem occurs, the front end uses Vue Axios, sends the request, the backend Java receives the code, realizes the front end separation

Backend on the receiving Fastjson receive JSON, for business processing, backend controller status:

1 /**2      * 3 * <p>4 * <p> Add Order5      *6      * @returnObject7      */8 @ResponseBody9@RequestMapping (value = "/addorder",//TenMETHOD =requestmethod.post) One      PublicObject AddOrder (@RequestBody basesinglelist basesinglelist) { A  -         returnOrderservice.addorder (basesinglelist); -  the}

Solution:

The controller enters the data normally, decomposes the data and re-sends the business logic in the SERVICEIMPL layer:

(1) When the data is passed in as Jsonobject, it is passed by the following method

1 /**2 * Place Order3      *4      * @parambasesinglelist5      * @returnObject6      */7 @Override8      PublicObject AddOrder (basesinglelist basesinglelist) {9 TenString Linearray =jsonarray.tojsonstring (basesinglelist); OneHashMap Parsemap = Json.parseobject (linearray,hashmap.class); A  -list<singleorder> singleorderlist = Json.parsearray (Json.parseobject (Linearray). getString ("SingleOrderList" ), Singleorder.class); -          the           for(Singleorder singleorder:singleorderlist) { -  - System.out.println (Singleorder.getuserid ()); -          } +}

(2) When data is passed to map

1 /**2 * Place Order3      *4      * @parambasesinglelist5      * @returnObject6      */7 @Override8      PublicObject AddOrder (basesinglelist basesinglelist) {9 Ten  One  Amap<string, object> map =NewHashmap<string, object>(); -Map.put ("Count", 2); -Map.put ("Studentlist", basesinglelist); theString JSON = json.tojsonstring (map,true); -  -  -HashMap Parsemap = Json.parseobject (JSON, HashMap.class); +List<basesinglelist> StudentList1 = (list<basesinglelist>) parsemap.get ("Basesinglelist"); -  +           for(Singleorder singleorder:singleorderlist) { A            at System.out.println (Singleorder.getuserid ()); -   } -  -}
