java 使用框架Spring MVC批量上傳圖片
運行環境：jdk1.8.0_17+tomcat 8 + spring：4.3.4+mybatis：3.2.7+ eclipse ide 2018+maven管理
最近寫項目時候用到上傳圖片文件等功能之前寫過沒有總結，以及記錄等，今天總結下寫的批量上傳圖片功能
前段只需要把所有的選擇的圖片提交上來即可，后台會逐個處理，並且會在服務器或者當前電腦自己新建一個存放圖片的文件夾，在application.properties配置里面你可以指定你所存放圖片的路徑，存圖片的文件夾，縮略圖的路徑，以及縮略圖的文件夾。
功能實現效果：
上傳圖片的Controller方法：
/** * 上傳圖片發布寶貝的控制器 * @return 圖片縮略圖imageList * @throws IOException * @throws FileNotFoundException */ @RequestMapping("/releaseBaby") public Object UploadPictree(@RequestParam("upload_file")CommonsMultipartFile[] files,@RequestParam("product") String JSON_prduct,HttpServletRequest request,HttpSession session) throws FileNotFoundException, IOException { //獲取前台傳過來的圖片，和JSON字符串，這里需要轉化成自己的po類到處需要在網上找JSON的幾個包才能完成轉化 JSONObject jsonObject = JSONObject.fromObject(JSON_prduct); //將字符串JSON數據轉化成自己的po 類 Product product = (Product)JSONObject.toBean(jsonObject, Product.class); //獲取配置文件中的路徑 ResourceBundle resource = ResourceBundle.getBundle("application"); Map<String, Object> map = new HashMap<String, Object>(); String imageURL = null ; map.put("title","false"); // //設置需要存的圖片地址 String pictureStorageAddress = resource.getString("realUploadPath")+request.getContextPath(); System.err.println("圖片存放地址："+pictureStorageAddress); //設置縮略圖存放地址 String thumbanilStorageAddress = resource.getString("realThumbnailPath")+request.getContextPath(); System.err.println("縮略圖存放地址："+thumbanilStorageAddress); //循環取出圖片 for (CommonsMultipartFile cmf : files) { //獲取文件全名 String fileName = cmf.getOriginalFilename(); String extensionName = fileName.substring(fileName.lastIndexOf(".")+1); System.out.println("獲取的擴展名："+ extensionName); String newFileName = String.valueOf(System.currentTimeMillis())+"."+extensionName; System.out.println("新的圖片名稱："+newFileName); // 存入圖片后獲得原圖的相對地址,將相對地址存入數據庫 imageURL= uploadPicturesService.uploadPictures(cmf, pictureStorageAddress, newFileName); System.err.println("原圖相對地址："+imageURL); // 獲取縮略圖的相對地址返回給前段使用 String thumbanilImageURL = thumbnailService.generateThumbnail(cmf, thumbanilStorageAddress, newFileName); System.err.println("縮略圖相對地址："+imageURL); } //獲取原圖的絕對路徑 String storePictureFolder =pictureStorageAddress+request.getContextPath()+resource.getString("storePictureFolder"); System.out.println("原圖的絕對路徑："+ storePictureFolder); //獲取縮略圖的絕對路徑 String realThumbanilPath =thumbanilStorageAddress+request.getContextPath()+resource.getString("thumbnailPictureFolder"); System.out.println("縮略圖的絕對路徑："+ realThumbanilPath); //讀取上傳圖片的圖片 List<String> realImageList = new ArrayList<String>(); //獲取縮略圖里面的所有圖片 realImageList = ProductImageListImpl.printFile(realThumbanilPath); //設置返回的imageList縮略圖 map.put("realImageList", realImageList); /** * 設置圖片相對地址到數據庫以及日期用戶等 */ String userInfo = (String) session.getAttribute("userInfo"); String userInfo1 = (String) request.getSession().getAttribute("userInfo"); System.out.println("Session值1"+userInfo +"Session值2"+userInfo1); product.setProductImage(imageURL); product.setProductDeliverytime(CustomDate.getPresentTime()); // //插入到數據庫 int temp = productService.inserProduct(product); if (temp > 0) { System.out.println("發布寶貝成功，已插入數據庫！"); map.put("message", "恭喜發布寶貝成功！"); map.put("title", true); } return map; }
uploadPictures 上傳圖片的實現方法:
/** * 上傳圖片並返回圖片的相對地址 * @throws IOException */ @Override public String uploadPictures(CommonsMultipartFile file, String realUploadPaht, String newFileName) throws IOException { ResourceBundle resource = ResourceBundle.getBundle("application"); String storePictureFolder = resource.getString("storePictureFolder"); //如果目錄不存在創建目錄 File uploadFile = new File(realUploadPaht+storePictureFolder); if (!uploadFile.exists()) { System.err.println(uploadFile.exists()); uploadFile.mkdirs(); } //創建輸入流 InputStream inputStream = file.getInputStream(); //生成輸出地址URL realUploadPaht=絕對路徑，storePictureFolder=存放圖片的文件夾名 +文件的名字 +file.getOriginalFilename() String outPutPath = realUploadPaht+storePictureFolder +"/"+ newFileName; //創建輸出流 以及新文件名 OutputStream outputStream = new FileOutputStream(outPutPath); //設置緩沖區 byte[] buffer = new byte[1024]; //輸入流讀入緩沖區，輸出流從緩沖區寫出 while (inputStream.read(buffer)>0) { outputStream.write(buffer); } outputStream.close(); //返回原圖上傳的相對地址 String relative_address = storePictureFolder +"/"+ newFileName; return relative_address; }
生成縮略圖的實現方法：
/** * 生成簡約圖的方法 * @author TangLie * */ @Service public class ThumbnailServiceImpl implements ThumbnailService{ //設置節約圖的寬度以及高度 public static final int heigth = 100; public static final int width = 100; @Override public String generateThumbnail(CommonsMultipartFile file, String realUploadPaht,String newFileName) throws IOException { // TODO Auto-generated method stub ResourceBundle resource = ResourceBundle.getBundle("application"); String thumbnailPictureFolder = resource.getString("thumbnailPictureFolder"); //如果目錄不存在創建目錄 File uploadFile = new File(realUploadPaht+thumbnailPictureFolder); if (!uploadFile.exists()) { uploadFile.mkdirs(); } //縮略圖保存的絕對地址 String des = realUploadPaht+thumbnailPictureFolder+"/"+newFileName; //按照我給的寬高生成縮略圖 Thumbnails.of(file.getInputStream()).size(width, heigth).toFile(des); //返回縮略圖地址 String relative_address = thumbnailPictureFolder+"/" + newFileName; return relative_address; } }
