fastjson直接转map复合类型报错

--------------------

### 问题解决: ###

1）报错代码:

String inventories = getFileString("D:\\data\\3\\库存.txt");
    Map<Shelf, List<InventoryBin>> shelfListMap = JSONObject.parseObject(pickOrderListStr, Map.class);

2) 报错内容

fastjson类型转成异常

3）修改之后(后面就没有报错):

/**
         * 将json读取字符串成为对象
         *
         * @param path 文件位置
         * @return map
         * @throws Exception
         */
        public Map<Shelf, List<ShelfBin>> getShelfBinList(String path) throws Exception {
            if (path == null || path.length() < 0) {
                return Maps.newHashMap();
            }
            Map<Shelf, List<ShelfBin>> shelfBinMap = new HashMap<>();
            String shelfListStr = getFileString(path);
            Map map = JSONObject.parseObject(shelfListStr, Map.class);
            for (Object o : map.entrySet()) {
                String shelfStr = ((Map.Entry) o).getKey().toString();
                String binsStr = ((Map.Entry) o).getValue().toString();
                Shelf shelf = JSONObject.parseObject(shelfStr, Shelf.class);
                List<ShelfBin> shelfBinList = JSONArray.parseArray(binsStr, ShelfBin.class);
                shelfBinMap.put(shelf, shelfBinList);
            }
            return shelfBinMap;
        }
