视觉化KBARS(4)-controller

今天要来写controller的部分，

(1)controller新称showOneMinKbar方法，
并从url取得start_date、end_date、stock_code的值，
带入後呼叫service oneMinKbar的方法，
最後将值传回client，回到showKbar页面

@RequestMapping(value = "/showOneMinKbar" , method = {RequestMethod.GET})
	public String oneMin(Model model, HttpServletRequest pRequest) throws Exception {
		String start_date = pRequest.getParameter("start_date") == null ? "" : pRequest.getParameter("start_date");
		String end_date = pRequest.getParameter("end_date") == null ? "" : pRequest.getParameter("end_date");
		String stock_code = pRequest.getParameter("stock_code") == null ? "" : pRequest.getParameter("stock_code");
		
		String kbar_data = shioajiService.oneMinKbar(start_date, end_date, stock_code);
		JSONObject jsonArray = new JSONObject(kbar_data);
		Gson gson  = new Gson();

		model.addAttribute("kbar_data", gson.toJson(jsonArray));

		return "showKbar";
	}

明天要写client的部分，
要依照controller的回传结果显示画面。

今天回传到前台的资料格式如下:
