问题描述

简要描述您碰到的问题。
toJavaObject在嵌套JsonObject时无法序列化
在很多情况下,嵌套json里层会被转化成linkedHashMap,但是linkedHashMap转成jsonobject会遇到问题

环境信息

请填写以下信息:

  • OS信息: [e.g.:CentOS 8.4.2105 4Core 3.10GHz 16 GB]
  • JDK信息: [e.g.:Openjdk 1.8.0_312]
  • 版本信息:[e.g.:Fastjson2 2.x.x]
    Fastjson2 2.0.12

重现步骤

如何操作可以重现该问题:

  1. 使用 xxx.xxx 方法
  2. 输入 ... 数据
  3. 出现 ... 错误
//可在此输入示例代码

class TestClass
private JSONObject data;

String a="{"test":"123465"}";

LinkedHashMap linkedHashMap = JSON.toJavaObject(a, LinkedHashMap.class);
JSONObject jsonObject =new JSONObject();
jsonObject.put("data",linkedHashMap);
System.out.println("a = " + linkedHashMap);

System.out.println("a = " + jsonObject.toJavaObject(TestClass.class));//报错
