【解决方案】Resolved [com.alibaba.fastjson.JSONException: exepct '[', but string, pos

使用fastjson，将字符串转数组时抛异常：

Resolved [com.alibaba.fastjson.JSONException: exepct '[', but string, pos

如下图中所示，result.getData()是一个字符串，我希望将它转为一个数组

 我的做法是：

String res = JSON.toJSONString(result.getData());
List<TFDepartment> departmentList = JSONArray.parseArray(res, TFDepartment.class);

所以抛异常了：Resolved [com.alibaba.fastjson.JSONException: exepct '[', but string, pos

解决方案如下：

String res = JSON.toJSON(result.getData()).toString();
List<TFDepartment> departmentList = JSONArray.parseArray(res, TFDepartment.class);
