Java中JSON字符串指定某个key进行加密

Question

Json字符串:{"code":"0000","success":true,"results":{"code":"0000","userId":364,"openid":"null","shopId":null,"brandId":66,"roleId":1,"entityName":null,"menuList":[{"id":258,"name":"xxx","pid":255,"type":2},{"id":259,"name":"xxx","pid":255,"type":2}],"loginName":"xxx"}}
需求：shopId，id 这两个属性值进行加密
有什么好的办法，正则替换什么的。

因为字符串内容是未知的，不能装换成JSON对象操作

已经解决了

哦看到了，其实也可以用instanceof判断，不过还是没indexOf判断的精确。
