發布時間：2025/3/19 javascript 16 豆豆

生活随笔收集整理的這篇文章主要介紹了 SpringMVC实现简单的图片上传DEMO 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

為什么80%的碼農都做不了架構師？>>> ??

先定義好picture的Entity.

前臺頁面:(css,js等沒給出)

后臺代碼:

//ManagerController.java @Controller @RequestMapping("/manage") public class ManageController {@Resourceprivate PictureService pictureService;@RequestMapping("/pictureList")public ModelAndView pictureList() {List<Picture> pictures = pictureService.listAll();ModelAndView mv = new ModelAndView();mv.addObject("pictures", pictures);mv.setViewName("manage/pictureList");return mv;}@RequestMapping("/addPicture")public ModelAndView addPicture() {ModelAndView mv = new ModelAndView();mv.setViewName("manage/addPicture");return mv;}@RequestMapping("/insertPic")public ModelAndView insertPic(Picture picture, MultipartFile uploadPic,HttpSession session) throws IllegalStateException, IOException {ModelAndView mv = new ModelAndView();String picPath = session.getServletContext().getRealPath("/") + "images/pictures/";String oldFileName = uploadPic.getOriginalFilename();String suffix = oldFileName.substring(oldFileName.lastIndexOf("."));SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");Date date = new Date();File newFile = new File(picPath + sdf.format(date) + suffix);picture.setPicAddr("images/pictures/" + sdf.format(date) + suffix);uploadPic.transferTo(newFile);System.out.println("最新插入的圖片ID是:" + pictureService.insertPic(picture));mv.setViewName("redirect:pictureList.html");return mv;} }

實現效果:

首先進行pictureList.jsp,點擊添加圖片:

會進入addPicture.jsp頁面,然后選擇圖片,確定添加

跳轉回到圖片顯示頁面:

遇到的一些問題:

添加的時候一開始亂碼,修改了一下配置文件就好了,在url后面添加

?useUnicode=true&characterEncoding=utf8.
