Json字符串转Json对象及Java对象

//json 字符串 转Java对象
 String confStr = "{\"key\":\"nihk\",\"secret\":\"qq123456\"}";
            JSONObject jsonObject = JSONObject.parseObject(confStr);
        　　AuthConf  conf = JSONObject.toJavaObject(jsonObject, AuthConf.class);
  　　　　　　System.out.println("conf=" + conf);


// json 数组 字符串 转JSONArray
 String confStr = "[{\"key\":\"nihk\"},{\"key\":\"nihk2\"}]";
 JSONArray jarr = JSONArray.parseArray(confStr);

// 以下方法得到的是JSONArray
            List<AuthConf> conf2 = JSONObject.toJavaObject(jarr,  List.class);
            System.out.println("conf2=" + conf2);

            List<AuthConf> conf22 = JSONArray.toJavaObject(jarr,  List.class);
            System.out.println("conf22=" + conf22);

            List<AuthConf> conf222 = JSON.toJavaObject(jarr,  List.class);
            System.out.println("conf222=" + conf222);

//输出
conf=AuthConf(key=nihk, secret=qq123456)
conf2=[{"key":"nihk"},{"key":"nihk2"}]
conf22=[{"key":"nihk"},{"key":"nihk2"}]
conf222=[{"key":"nihk"},{"key":"nihk2"}]
