解析JSON字符串

web service返回json字符串后需要解析，举例如下：

package com.glaway.offline.test.main;

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;

public class JsonTest {

    public static void main(String[] args) {
        test1();
        

    }
    
    /**
     * 解析json字符串
     */
    public static void test1(){
        String json = "{\"code\":\"success\",\"data\":[{\"age\":25,\"name\":\"1\"},{\"age\":8,\"name\":\"2\"}]}";
        if(json != null){
            JSONObject jsonObject = JSONObject.parseObject(json);
            if(jsonObject.get("code") != null){
                String code = (String) jsonObject.get("code");
                if(code.equals("success")){
                    JSONArray jsonArray = (JSONArray) jsonObject.get("data");
                    if(jsonArray != null){
                        for(int i=0;i<jsonArray.size();i++){
                            JSONObject object = jsonArray.getJSONObject(i);
                            String name = (String) object.get("name") != null?(String) object.get("name"):null;
                            Integer age = object.get("age")!=null?(Integer)object.get("age"):null;
                            System.out.println(name+":"+age); //1:25、2:8
                        }
                    }
                }
            }
            
        }
        
        
    }

}
