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
代码:
例如:
try {
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
String selectName = new String(request.getParameter("selectName").getBytes("iso-8859-1"),"utf-8");//用request获取URL传递的中文参数,防止乱码
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
if (!selectName.equals("")) {
historyEvent = historyEventService.getHistoryEventByName(projectId, selectName);//获取对象
response.setContentType("application/json; charset=utf-8");
JSONObject responseJSONObject = JSONObject.fromObject(historyEvent); //将实体对象转换为JSON Object转换
out.print(responseJSONObject.toString());
out.flush();
out.close();
}
} catch (Exception e) {
e.printStackTrace();
}
