- 大神帮忙解答一下这个json数据怎么在java里用json lib解析存放到List里
-
[
{
"city": "",
"citys": [
{
"city": "北京",
"id": 2,
"level": 2,
"province": "北京",
"seq": 0,
"x": 116.405,
"y": 39.905
}
],
"id": 1,
"level": 1,
"province": "北京",
"region": "华北地区",
"seq": 0,
"x": 116.405,
"y": 39.905
},
{
"city": "",
"citys": [
{
"city": "上海",
"id": 4,
"level": 2,
"province": "上海",
"seq": 0,
"x": 121.473,
"y": 31.2317
}
],
"id": 3,
"level": 1,
"province": "上海",
"region": "华东地区",
"seq": 0,
"x": 121.473,
"y": 31.2317
}
]
使用json-lib很简单，实例代码：
public class JsonLib {
public static void main(String[] args) {
String json = "[]";//你上面的字符串
JSONArray jsonArray = JSONArray.fromObject(json);
Object array = JSONArray.toArray(jsonArray);
System.out.println(array);
System.out.println(Arrays.asList((Object[]) array));
}
}
需要导入jar，详细的json-lib的使用过程参考:http://www.cnblogs.com/sunzn/archive/2013/02/12/2910241.html
