spring boot 模板生成 springboot下载模板

项目需要下载导入模板，springboot使用如下下载方式可解决问题：

/**
	 *  导入模板下载
	 * @param req
	 * @param resp
	 * @param context
	 * @return
	 */
	@RequestMapping(value = "wSku/downLoadFile", method = {RequestMethod.POST, RequestMethod.GET})
	public @ResponseBody void downLoadFile(HttpServletRequest req,HttpServletResponse resp) {
		String fileDownName ="价格表-模板.xlsx";
		logger.debug("下载模板文件名称："+fileDownName);
		try {
	    	InputStream fis = WSkuController.class.getResourceAsStream("/exceltemplet/priceListTemplate.xlsx");
	        byte[] buffer = new byte[fis.available()];
	        fis.read(buffer);
	        fis.close();
		    response.reset();
		    response.setContentType("bin");

		    String fileNames = fileDownName;
	        String agent = request.getHeader("USER-AGENT");    

	        String codedfilename = "";
	        if (null != agent && -1 != agent.indexOf("MSIE") || null != agent && -1 != agent.indexOf("Trident")) {// ie    

                 String name = java.net.URLEncoder.encode(fileNames, "UTF8");    

                 codedfilename = name;    
             } else if (null != agent && -1 != agent.indexOf("Mozilla")) {// 火狐,chrome等    

                 codedfilename = new String(fileNames.getBytes("UTF-8"), "iso-8859-1");    
             }    		    response.addHeader("Content-Disposition", "attachment; filename=\"" + codedfilename + "\"");
	        response.getOutputStream().write(buffer);
	    } catch (IOException e) {
	        e.printStackTrace();
	        logger.debug("下载价格表-模板文件报错"+e.getMessage(), e);
	    }
	}

其中文件存放在如下路径下：/imfbp-istorewares-admin/src/main/resources/exceltemplet/priceListTemplate.xlsx
