一个复杂Json的解析

 1 {
 2     "website": {
 3         "1": {
 4             "basic": {
 5                 "homepage": "http://pythontip.sinaapp.com/",
 6                 "homename": "Python之禅--大道至简"
 7             },
 8             "list": {
 9                 "2": {
10                     "childpage": "http://pythontip.sinaapp.com/study/books/pythontutorial3-master",
11                     "chilename": "Python 入门指南"
12                 },
13                 "3": {
14                     "childpage": "http://pythontip.sinaapp.com/coding/code_oj",
15                     "chilename": "挑战Python"
16                 }
17             }
18         }
19     }
20 }

我使用的是Google的Gson对其做解析，
下载gson jar包

 1 import java.io.Serializable;
 2 
 3 public class ChildPage implements Serializable {
 4 
 5     /**
 6      * 
 7      */
 8     private static final long serialVersionUID = 1L;
 9     
10     private String childpage;
11     private String chilename;
12     
13     //getter and setter
14 
15     @Override
16     public String toString() {
17         return "ChildPage [childpage=" + childpage+ ", chilename=" + chilename + "]";
18     }
19 }

 1 import java.io.Serializable;
 2 
 3 public class ParentPage implements Serializable {
 4 
 5     /**
 6      * 
 7      */
 8     private static final long serialVersionUID = 1L;
 9     
10     private String hostpage;
11     private String homename;
12     
13         //getter and setter
14     
15     @Override
16     public String toString() {
17         return "ParentPage [homepage=" + homepage+ ", homename=" + homename + "]";
18     }
19 }

 1 import java.io.Serializable;
 2 import java.util.HashMap;
 3 
 4 public class ParentAndChildPage implements Serializable {
 5 
 6     
 7     /**
 8      * 
 9      */
10     private static final long serialVersionUID = 1L;
11     
12     private ParentPage basic;
13     private HashMap<String,ChildPage> list;
14     
15         //getter and setter
16     
17     @Override
18     public String toString() {
19         return "ParentAndChildPage [basic=" + basic + ", list=" + list + "]";
20     }
21 }

 1 import java.io.Serializable;
 2 import java.util.HashMap;
 3 
 4 public class Website implements Serializable {
 5 
 6     /**
 7      * 
 8      */
 9     private static final long serialVersionUID = 1L;
10     
11     private HashMap<String,ParentAndChildPage> website;
12 
13     //getter and setter
14 
15     @Override
16     public String toString() {
17         return "Website [website=" + website + "]";
18     }
19 }

1 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。
