简述:
在servlet填充Response的时候,做JSON格式的数据转换
使用的类是net.sf.json.JSONObject,传入response对象和返回的显示类,修改response,返回前台JSON格式数据
/** * 以JSON格式输出 * @param response */ protected void responseOutWithJson(HttpServletResponse response, Object responseObject) { //将实体对象转换为JSON Object转换 JSONObject responseJSONObject = JSONObject.fromObject(responseObject); response.setCharacterEncoding("UTF-8"); response.setContentType("application/json; charset=utf-8"); PrintWriter out = null; try { out = response.getWriter(); out.append(responseJSONObject.toString()); logger.debug("返回是 "); logger.debug(responseJSONObject.toString()); } catch (IOException e) { e.printStackTrace(); } finally { if (out != null) { out.close(); } } }
