Java中Json解析

首先准备一个JSON格式的字符串
* String JsonStr = "{object:{persons:" +
"[{name:'呵呵',image:'http://10.0.159.132:8080/Web/s1.png'}," +
"{name:'哈哈',image:'http://10.0.159.132:8080/Web/s1.png'}," +
"{name:'嘿嘿',image:'http://10.0.159.132:8080/Web/s2.jpg'}]}}";

* 然后定义一个Person类
*
*

 class Person{
     private String name,image;

     public String getName() {
         return name;
     }

     public void setName(String name) {
         this.name = name;
     }

     public String getImage() {
         return image;
     }

     public void setImage(String image) {
         this.image = image;
     }

 }

下面是一个Json解析的程序代码

 class MyDay17Xml {
     //json字符串
     static String JsonStr = "{object:{persons:" +
             "[{name:'呵呵',image:'http://10.0.159.132:8080/Web/s1.png'}," +
             "{name:'哈哈',image:'http://10.0.159.132:8080/Web/s1.png'}," +
             "{name:'嘿嘿',image:'http://10.0.159.132:8080/Web/s2.jpg'}]}}";

     public static void main(String []args) throws JSONException{
         List<Person> list=jsonStrToList(JsonStr);
         System.out.println(list.size());
     }
     /**
      *
      *
      *
      */
     public static List<Person> jsonStrToList(String jsonStr) throws JSONException{
         List<Person> list=new ArrayList<Person>();

         //通过字符串，获得最外部的json对象
         JSONObject jsonObj=new JSONObject(jsonStr);
         //通过属性名，获得内部的对象
         JSONObject jsonPersons=jsonObj.getJSONObject("object");
         //获得json对象组
         JSONArray arr=jsonPersons.getJSONArray("persons");
         for(int i=0;i<arr.length();i++){
             //循环对象，并通过getString("属性名");来获得值
             JSONObject tempJson=arr.getJSONObject(i);
             Person person=new Person();

             person.setName(tempJson.getString("name"));
             person.setImage(tempJson.getString("image"));
             list.add(person);
         }
         return list;

     }

 }
