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
*
*
1 class Person{ 2 private String name,image; 3 4 public String getName() { 5 return name; 6 } 7 8 public void setName(String name) { 9 this.name = name; 10 } 11 12 public String getImage() { 13 return image; 14 } 15 16 public void setImage(String image) { 17 this.image = image; 18 } 19 20 }
下面是一个Json解析的程序代码
1 class MyDay17Xml { 2 //json字符串 3 static String JsonStr = "{object:{persons:" + 4 "[{name:'呵呵',image:'http://10.0.159.132:8080/Web/s1.png'}," + 5 "{name:'哈哈',image:'http://10.0.159.132:8080/Web/s1.png'}," + 6 "{name:'嘿嘿',image:'http://10.0.159.132:8080/Web/s2.jpg'}]}}"; 7 8 public static void main(String []args) throws JSONException{ 9 List<Person> list=jsonStrToList(JsonStr); 10 System.out.println(list.size()); 11 } 12 /** 13 * 14 * 15 * 16 */ 17 public static List<Person> jsonStrToList(String jsonStr) throws JSONException{ 18 List<Person> list=new ArrayList<Person>(); 19 20 //通过字符串,获得最外部的json对象 21 JSONObject jsonObj=new JSONObject(jsonStr); 22 //通过属性名,获得内部的对象 23 JSONObject jsonPersons=jsonObj.getJSONObject("object"); 24 //获得json对象组 25 JSONArray arr=jsonPersons.getJSONArray("persons"); 26 for(int i=0;i<arr.length();i++){ 27 //循环对象,并通过getString("属性名");来获得值 28 JSONObject tempJson=arr.getJSONObject(i); 29 Person person=new Person(); 30 31 person.setName(tempJson.getString("name")); 32 person.setImage(tempJson.getString("image")); 33 list.add(person); 34 } 35 return list; 36 37 } 38 39 }
