Apache图片服务器 ，图片上传

[路口xia车]

Apache 作为网站图片服务器，上传是如何处理的。直接用 http： RRL 形式上传能行否？还是要用ftp上传图片！请多指教！

这个上传首先要用到两个来源包，一个io，一个fileupload，然后有两种方法，首先你要不用struts2框架的话就这样: public class UploadServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doPost(request, response); } /** * read方法一次只读一个字节，read(byte[] b)也是读取一个字节，只不过要将字节放入到byte[]中 */ public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { //4.获得临时文件的路径 String tempPath = this.getServletContext().getRealPath("/temp"); System.out.println(tempPath); //获得下载文件的路径 String uploadPath = this.getServletContext().getRealPath("/fileupload"); System.out.println(uploadPath); //1.获得工厂 DiskFileItemFactory factory = new DiskFileItemFactory(); //3.设置缓冲区大小 factory.setSizeThreshold(10000*1024); //5.设置临时文件（其存放的位置） factory.setRepository(new File(tempPath)); //2.获得ServletFileUpload对象,此处并没有通过静态方法获得,有些疑惑 ServletFileUpload upload = new ServletFileUpload(factory); String message = null; //设置文件名中文乱码 upload.setHeaderEncoding("utf8"); //6.获得FileItem对象的list集合 try { List<FileItem> items = upload.parseRequest(request); for(FileItem item : items){ if(item.isFormField()){ //普通字段 System.out.println(item.getFieldName()); System.out.println(item.getString()); }else{ //上传字段 InputStream ins = item.getInputStream(); //设置下载文件的绝对路径 String fileName = item.getName(); //去掉文件名的前缀，fileName的前缀，截取文件名 int index = fileName.lastIndexOf("\\"); if(index>0){ fileName = fileName.substring(index); } //获取UUID字符串，添加到文件名之前，可以保证文件名不相同 String uuid = UUID.randomUUID().toString(); File file = new File(uploadPath+"\\"+uuid+"_"+fileName); OutputStream out = new FileOutputStream(file); byte[] b = new byte[1024]; int step = 0; while((step=ins.read(b))!= -1){ out.write(b); } ins.close(); out.close(); message = "保存成功"; } } } catch (FileUploadException e) { message = "保存失败"; e.printStackTrace(); }finally{ request.setAttribute("message", message); request.getRequestDispatcher("/upload/result.jsp").forward(request, response); } } } 当然如果你用struts2会很简单，只需要定义3个参数，然后提供setget方法，最后核心方法这样: public String saveFile() throws Exception{ System.out.println("UploadAction.saveFile()"); //实现上传 //设置上传文件的路径 String uploadPath = ServletActionContext.getServletContext().getRealPath("upload"); uploadPath = uploadPath + "/" +uploadImageFileName; File uploadFile = new File(uploadPath); //拷贝文件 FileUtils.copyFile(uploadImage, uploadFile); return SUCCESS; } 这样就搞定了啊...当然用modeldriven更简单，不多说了就，给我点分让我擦擦汗吧,,☺

java IO流

用apache的组件包 fileupload.jar

为何不用第三方的，诸如七牛之类的。自己运维成本太高，还的做cdn
