问题描述

fastjson2 2.0.51

final var str = "{\"context\":{\"$ref\":\"@\"}}";
JSON.parseObject(str, Map.class);

报错:

Exception in thread "main" com.alibaba.fastjson2.JSONException: reference path invalid : @
at com.alibaba.fastjson2.JSONReader.handleResolveTasks(JSONReader.java:311)
at com.alibaba.fastjson2.JSON.parseObject(JSON.java:866)

在 fastjson1 中, 可以被解析为 {"context":{"context":...}}
