在mongodb 中字符串反序列化成 objectid问题

1

String str = " { "_id" : "5aeab29ad45ca900017cd1b5"}"; 怎么直接调用 JSON.parseObject(String txt) 得到ObjectId对像？

可以支持反序列化私有setter吗？

3

``` import com.alibaba.fastjson.JSONObject class User{ var name: String? = null private set } fun main(args: Array) { val user = JSONObject.parseObject("{\"name\":\"fastjson\"}", User::class.java) println(user.name) } ``` 运行结果：```null``` 期望结果：```fastjson``` @wenshao 拜托支持一下~
