java - How to use Jackson to deserialise Array Like This? -

how deserialise simple? json like:

{ "ok": 1, "data": {     "a": [         {             "brand": "aman",             "logo": "http://zxmall.bluedoor.com.cn/uploads/logo/61.png"         }     ],     "b": [         {             "brand": "base-ds",             "logo": "http://zxmall.bluedoor.com.cn/uploads/logo/24.png"         },         {             "brand": "bb",             "logo": "http://zxmall.bluedoor.com.cn/uploads/logo/46.png"         },         {             "brand": "banane",             "logo": "http://zxmall.bluedoor.com.cn/uploads/logo/11.png"         }      ],     "c": [         {             "brand": "cat",             "logo": "http://zxmall.bluedoor.com.cn/uploads/logo/78.png"         },         {             "brand": "car",             "logo": "http://zxmall.bluedoor.com.cn/uploads/logo/129.png"         }     ] } } 

from [a-z].

my code below:

reslutmod data = jsonutil.jsontomod(json, reslutmod.class); 

in jsonutil:

public static  <t> t jsontomod(string jsonstring, class<t> clazz) {     if (stringutils.isempty(jsonstring)) {          return null;     }     try {         return jsonmapper                 .getinstance()                 .getjsonmapper().readvalue(jsonstring, clazz);     } catch (ioexception e) {         e.printstacktrace();         return null;     } } 

javabean:

 public class reslutmod {     public int ok;     public brandlistmod data;  } 

javabean2:

 public class brandlistmod {     public arraylist<cardbrandmodel> a;     public arraylist<cardbrandmodel> b;     public arraylist<cardbrandmodel> c;     public arraylist<cardbrandmodel> d;     public arraylist<cardbrandmodel> e;     public arraylist<cardbrandmodel> f;     public arraylist<cardbrandmodel> g;     public arraylist<cardbrandmodel> h;     public arraylist<cardbrandmodel> i;     public arraylist<cardbrandmodel> j;     public arraylist<cardbrandmodel> k;     public arraylist<cardbrandmodel> l;     public arraylist<cardbrandmodel> m;     public arraylist<cardbrandmodel> n;     public arraylist<cardbrandmodel> o;     public arraylist<cardbrandmodel> p;     public arraylist<cardbrandmodel> q;     public arraylist<cardbrandmodel> r;     public arraylist<cardbrandmodel> s;     public arraylist<cardbrandmodel> t;     public arraylist<cardbrandmodel> u;     public arraylist<cardbrandmodel> v;     public arraylist<cardbrandmodel> w;     public arraylist<cardbrandmodel> x;     public arraylist<cardbrandmodel> y;     public arraylist<cardbrandmodel> z; } 

i don't think way. can do?

you can use map here.

e. g. :

class reslutmod {     public int ok;     public map<string, arraylist<cardbrandmodel>> data;      public int getok() {         return ok;     }      public void setok(int ok) {         this.ok = ok;     }      public map<string, arraylist<cardbrandmodel>> getdata() {         return data;     }      public void setdata(map<string, arraylist<cardbrandmodel>> data) {         this.data = data;     }  } 

where class cardbrandmodel :

class cardbrandmodel {      string brand;      string logo;      public string getbrand() {         return brand;     }      public void setbrand(string brand) {         this.brand = brand;     }      public string getlogo() {         return logo;     }      public void setlogo(string logo) {         this.logo = logo;     }  }
