一个复杂Json的解析

 {
     "website": {
         "1": {
             "basic": {
                 "homepage": "http://pythontip.sinaapp.com/",
                 "homename": "Python之禅--大道至简"
             },
             "list": {
                 "2": {
                     "childpage": "http://pythontip.sinaapp.com/study/books/pythontutorial3-master",
                     "chilename": "Python 入门指南"
                 },
                 "3": {
                     "childpage": "http://pythontip.sinaapp.com/coding/code_oj",
                     "chilename": "挑战Python"
                 }
             }
         }
     }
 }

我使用的是Google的Gson对其做解析，
下载gson jar包

 import java.io.Serializable;

 public class ChildPage implements Serializable {

     /**
      *
      */
     private static final long serialVersionUID = 1L;

     private String childpage;
     private String chilename;

     //getter and setter

     @Override
     public String toString() {
         return "ChildPage [childpage=" + childpage+ ", chilename=" + chilename + "]";
     }
 }

 import java.io.Serializable;

 public class ParentPage implements Serializable {

     /**
      *
      */
     private static final long serialVersionUID = 1L;

     private String hostpage;
     private String homename;

         //getter and setter

     @Override
     public String toString() {
         return "ParentPage [homepage=" + homepage+ ", homename=" + homename + "]";
     }
 }

 import java.io.Serializable;
 import java.util.HashMap;

 public class ParentAndChildPage implements Serializable {

     /**
      *
      */
     private static final long serialVersionUID = 1L;

     private ParentPage basic;
     private HashMap<String,ChildPage> list;

         //getter and setter

     @Override
     public String toString() {
         return "ParentAndChildPage [basic=" + basic + ", list=" + list + "]";
     }
 }

 import java.io.Serializable;
 import java.util.HashMap;

 public class Website implements Serializable {

     /**
      *
      */
     private static final long serialVersionUID = 1L;

     private HashMap<String,ParentAndChildPage> website;

     //getter and setter

     @Override
     public String toString() {
         return "Website [website=" + website + "]";
     }
 }

 Website website = new Gson().fromJson(json, Website.class);

注意：Java Bean的属性必须和Json串的key值对应。
