java中的json解析_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 Text {

//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 list = jsonStrToList(JsonStr);

System.out.println(list.size());

}

public static List jsonStrToList(String jsonStr) throws JSONException {

List list = new ArrayList();

//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;

}

}
