直接上代码:

    public static void main(String[] args) {Map<String,String> map = new HashMap<>();map.put("id","1");map.put("openId","wafawf1121");map.put("latitude","112.2");map.put("longitude","22.5");JSONObject jsonObject = JSONObject.parseObject(JSON.toJSONString(map));bikeLog bikeLog = jsonObject.toJavaObject(bikeLog.class);System.out.println(bikeLog.getId()+bikeLog.getLatitude());}//Javabean对象转换成String类型的JSON字符串
JSONObject.toJSONString(Javabean对象)//String类型的JSON字符串转换成Javabean对象
JSONObject.toJavaObject(JSON字符串,Javabean.class)//Json字符串转换成JSONObject对象
JSONObject.parseObject(JSON字符串)//JSON字符串转换成Javabean对象
JSONObject.parseObject(JSON字符串,Javabean.class)例如
Refund r = new Refund();
String jsonStr = JSONObject.toJSONString(r);String jsonStr = "{\"msg\":\"ZhangSan\"}";
Refund r = JSONObject.toJavaObject(jsonStr,Refund.class);JSONObject jsonObject = JSONObject.parseObject(jsonStr);Refund r = JSONObject.parseObject(jsonStr,Refund.class);
