com.alibaba.fastjson2.JSONObject#toJavaObject(java.lang.Class<T>, com.alibaba.fastjson2.JSONReader.Feature...)bug

[fun-li]

问题描述

该方法在开启JSONReader.Feature.SupportSmartMatch模式后，只能解析最外层的下划线变量，内层无法解析到，例如下面的dept_order_list中的dept_id获取到的值为空

  "errmsg": "ok",

    ],
    "dept_order_list": [

        "dept_id": 111111111,
        "order": 1111111111111

    ],
    "email": "",

    "hide_mobile": false,
