1. 把java 对象列表转换为json对象数组,并转为字符串 JSONArray array = JSONArray.fromObject(list); String jsonstr = array.toString(); 2. 把java对象转换成json对象,并转化为字符串 JSONObject object = JSONObject.fromObject(user); Log4jInit.ysulogger.debug(object.toString()); 3.把JSON字符串转换为...
registrationdate { get; set; } public string userrole { get; set; } public string approveduser { get; set; } } } Tuesday, November 27, 2018 9:13 PMNo, just return whatever you need. If a List<User> fits your needs, just return that. According to the JSON you shown it seems ...
将每个List<String>对象添加到List<List<String>>中。 最后,返回转换后的List<List<String>>对象。 以下是一个示例代码: 代码语言:txt 复制 import json def json_to_list(json_str): data = json.loads(json_str) result = [] for item in data: sublist = [] for value in item: sublist.app...
You can also get a string representation of a JSON value (serialize): // explicit conversion to string std::string s = j.dump(); // {"happy":true,"pi":3.141} // serialization with pretty printing // pass in the amount of spaces to indent std::cout << j.dump(4) << std::endl...
String jsonStr = "{\"userName\":\"admin\"}"; Refund r = JSONObject.toJavaObject(jsonStr,User.class); JSONObject jsonObject = JSONObject.parseObject(jsonStr); User u = JSONObject.parseObject(jsonStr,User.class); 集合转换 List<ExamListInVO> list = new ArrayList<ExamListInVO>(); ...
list -- 列表 string str number (int) int number (real) float true True false False null None 它还将“NaN”、“Infinity”和“-Infinity”理解为它们对应的“float”值,这超出了JSON规范。 如果指定了object_hook,它将被调用并传入每个已解码 JSON 对象的结果,并且其返回值将被用来替代给定的dict。 它...
