问题描述
I'm开发使用了大量的JSON的，我是用GSON解析一个应用程序，但它很慢，现在我正尝试使用杰克逊，在汇入作业第一次，我听说过，所以我不知道如何使用它非常好。
我的JSON像汇入作业：
I´m developing an app that uses a lot of json, I was using Gson to parse, but it was really slow and now I´m trying to use Jackson, it´s the first time that I heard of it, so I don´t know how to use it very well.My json it´s like:
{
"action": "login",
"status": true,
"message": "OK",
"duration": 144,
"response": {
"token": "b6a1e3b87c86531d91afa91bb23aca46"
}
}
和我的类反序列化一样汇入作业：
And my class to deserialize it´s like:
public class HttpWebServiceObject {
private String action;
private boolean status;
private String message;
private String duration;
private String response;
//getters and setters
}
有人可以帮助我？
Someone could help me with this?
先谢谢了。
编辑：
我能有这样一个JSON太：
I can have a json like this too:

"action": "getUserFollowers",
"status": true,
"message": "OK",

"response": [

"following": false,
"numfollowing": 26,
"numfollowers": 221
}
]
}
我怎么能这样做一般的解析来deseriliaze这个，只是采取应对作为一个字符串？
How I could do a general parse to deseriliaze this and just take response as a string?
推荐答案
原来这就是你的 HttpWebServiceObject.java 和 Response.java 应该像。这是使用这需要JSON并将其转换为的POJO生成。一旦你有这两个类则可以使用 ObjectMapper 来映射JSON字符串这些类。
So this is what your HttpWebServiceObject.java and Response.java should look like. This was generated using this website which takes json and converts it to pojos. Once you have these two classes you can then use an ObjectMapper to map the json string to these classes.
