JSON获取字符串数组

使用到的jar包：fastjson-1.2.2.jar

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

1.格式一：

{“aa”:["11","22","33"]}

public static void main(String[] args) {
        String str = "{'aa':['11','22','33']}";
        JSONObject jsonObject = JSONObject.parseObject(str);
        JSONArray jsonArray = jsonObject.getJSONArray("aa");
        System.out.println(jsonArray.get(0));//11
        System.out.println(jsonArray.get(1));//22
        System.out.println(jsonArray.get(2));//33
}

2.格式二：

"aaa" : [{"bb": "11","cc": "22","dd": "33"},{"bb": "44","cc": "55","dd": "66"}]

public static void main(String[] args) {
    String str = "{'aa':[{'bb':'11','cc':'22','dd':'33'},{'bb':'44','cc':'55','dd':'66'}]}";
    JSONObject jsonObject = JSONObject.parseObject(str);
    JSONArray jsonArray = jsonObject.getJSONArray("aa");
    for (int i = 0; i < jsonArray.size(); i++) {
        JSONObject object = (JSONObject) jsonArray.get(i);
        System.out.println("bb:" + object.getString("bb")
                + " cc:" + object.getString("cc")
                + " dd:" + object.getString("dd"));
    }
}
