一、這個處理器用於掃二維碼的展現---h5頁面php
@RequestMapping(value = "/phone") @Controller public class PhonePicController extends BaseController{ @Autowired PhonePicService pic; protected static String PHONEURL = "http://localhost:8087/flag="; private static final Log logger = LogFactory.getLog(PhonePicController.class); //展現頁面 @RequestMapping(value = "/page", method = RequestMethod.GET) public String page(HttpServletRequest request) { logger.info(request.getParameter("flag")); return "upload/load_photo.ftl"; }
注意:由於前臺傳過來的圖片是base64二進制,因此我這邊後臺進行了處理轉化了圖片路徑存服務器css
//手機上傳圖片圖片 @RequestMapping(value = "/pic", method = RequestMethod.POST) @ResponseBody public ResultInfo pic(HttpServletRequest request, String file,String flag,Integer side) { side=1; if (file == null && StringUtil.isEmptyTrim(file)) { logger.error("web圖片單獨上傳異常"); } System.out.println("圖片----------" + file); //寫個路徑,把base64轉路徑 String fileprex = "/resources/upload"; String filename = UUID.randomUUID().toString() + ".jpg"; String picpath = request.getSession().getServletContext().getRealPath(fileprex) + filename; System.out.println(picpath); System.out.println(flag); System.out.println(side); if (file != null) { Base64Utils.Base64ToImage(file, picpath); } Integer i = pic.save(fileprex + filename,flag); if (i < 0) { logger.error("失敗"); } return ResultInfo.success("上傳圖片成功",i); } //獲取數據庫路徑,回顯數據 @RequestMapping(value = "/byurl", method = RequestMethod.POST) @ResponseBody public ResultInfo findbypic(HttpServletRequest request,String flag) { if (flag == null && StringUtil.isEmptyTrim(flag)) { logger.error("web圖片單獨上傳異常"); } System.out.println(flag); String url = pic.findbypic(flag); System.out.println(url); String path="http://localhost:8087"; String data=path+url; return ResultInfo.success("ok",data); } // @RequestMapping(value = "/bycomid", method = RequestMethod.POST) @ResponseBody public ResultInfo bycomid(HttpServletRequest request,String tokenId, String file,String flag,Integer compId) { UserInfo userInfo; try { userInfo = getUserInfo(tokenId); } catch (Exception e) { return ResultInfo.reLogin(); } if (file == null && StringUtil.isEmptyTrim(file)) { logger.error("web圖片單獨上傳異常"); } System.out.println("圖片----------" + file); //寫個路徑,把base64轉路徑 String fileprex = "/resources/upload/"; String filename = UUID.randomUUID().toString() + ".jpg"; String picpath = request.getSession().getServletContext().getRealPath(fileprex) + filename; if (file != null) { Base64Utils.Base64ToImage(file, picpath); } Integer i = pic.saveComid(userInfo, fileprex + filename, flag, compId); if (i < 0) { logger.error("失敗"); } return ResultInfo.success("ok", 200); }
