求解组会任务，如何给原始json日志脱敏?

求解方案，就是对原始json的数据进行脱敏，在原始json的基础上对用户名，邮箱，手机号等信息脱敏，数据量很大，求解可行的解决方案
,类似以下这种json数据，数据已经过处理.

大概就是自定义一个序列化类，通过键来判断一下要不要就值进行特殊处理，希望对你有帮助

class MyStringSerializer extends JsonSerializer<String> {

    @Override
    public void serialize(String s, JsonGenerator jgen, SerializerProvider serializerProvider) throws IOException {
        String currentName = jgen.getOutputContext().getCurrentName();
        if ("就是它".equals(currentName)) {
            jgen.writeString(s + "骚操作");
        }else{
            jgen.writeString(s);
        }
    }
}

像java jackson是可以自己指定字段序列化和反序列化的逻辑处理的，你要脱敏，直接json工具就可以实现脱敏，为什么还要转完以后再对字符串做处理？
