### 期待的正确结果
*对您期望发生的结果进行清晰简洁的描述。*
JSON.parseArray(jsonData, clazz);
希望能转换出 对应属性 的值
### 相关日志输出

能帮忙简化一个重方便重现问题的testcase么？
JSON.parseArray(jsonData, clazz); 定义好 对应实体类(FieLdsModel ConfigModel ....) 放入上面 jsonData 数据 调用JSON.parseArray(jsonData, clazz) 即可
JSON.parseArray(jsonData, clazz) , 这里传入的clazz是什么？很抱歉，一直没搞清楚你问题
class 是 FieLdsModel 这个类
JSON.parseArray(jsonData, FieLdsModel.class)
FieLdsModel ff = JSON.parseArray(jsonData, FieLdsModel.class)
对应得 config属性 里面 是null
不知我 描述清楚没 这个在1.2.x 是会有值得 但是2.x得 版本 好像不行
可以通过JSONField额外配置
@Data
public static class FieLdsModel {
@JSONField(alternateNames = "__config__")
private ConfigModel config;
支持__会有别别的兼容问题，所以就不支持连续下划线了

@Data public static class FieLdsModel { @JSONField(alternateNames = "__config__") private ConfigModel config;支持__会有别别的兼容问题，所以就不支持连续下划线了
好 我试试 谢谢 温大佬 因为1.2.83 我一直没升级 是因为这个版本 是支持__ 2.x 我就没升级上去
