1. json轉字串
String requestStr = JSON.toJSONString(requestObj);
2. json轉物件
String responseStr = HttpHelper.post(targetUrl, requestStr, token);
Object[] responseObj = JSON.parseObject(responseStr, Object[].class);
3. 一個物件成員變數值複製到另一物件中:
使用package org.springframework.beans;包下的BeanUtils.copyProperties(source, target); 即可
BeanUtils.copyProperties(request, MDevice);
複製的資料在request中,使用時用.訪問
4. 字串轉json:
String responseStr = HttpHelper.post(url, requestStr, token);
JSONObject responseJson = (JSONObject) JSON.parse(responseStr);
