四。还有两个简单jsp文件index.jsp,error.jsp可以自己写。
五。action文件
package com.fangchuang.action; /** * @author anEngineer 处理上传文件action */ public class UploadAction extends Action { public ActionForward execute( ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { //可以随便转载,请保留出自http://www.javaresearch.org 作者anEngineer DynaActionForm fileForm = (DynaActionForm) form; String[] types = (String[]) fileForm.get("type"); String[] names = (String[]) fileForm.get("name"); FormFile file0 = (FormFile) fileForm.get("file0"); FormFile file1 = (FormFile) fileForm.get("file1"); FormFile file2 = (FormFile) fileForm.get("file2"); FormFile file3 = (FormFile) fileForm.get("file3"); FormFile file4 = (FormFile) fileForm.get("file4"); FormFile file5 = (FormFile) fileForm.get("file5"); FormFile file6 = (FormFile) fileForm.get("file6"); FormFile file7 = (FormFile) fileForm.get("file7"); FormFile file8 = (FormFile) fileForm.get("file8"); FormFile file9 = (FormFile) fileForm.get("file9"); Map<String, FormFile> fileMap = new HashMap<String, FormFile>(); fileMap.put("file0" + "*" + types[0] + "*" + names[0], file0); fileMap.put("file1" + "*" + types[1] + "*" + names[1], file1); fileMap.put("file2" + "*" + types[2] + "*" + names[2], file2); fileMap.put("file3" + "*" + types[3] + "*" + names[3], file3); fileMap.put("file4" + "*" + types[4] + "*" + names[4], file4); fileMap.put("file5" + "*" + types[5] + "*" + names[5], file5); fileMap.put("file6" + "*" + types[6] + "*" + names[6], file6); fileMap.put("file7" + "*" + types[7] + "*" + names[7], file7); fileMap.put("file8" + "*" + types[8] + "*" + names[8], file8); fileMap.put("file9" + "*" + types[9] + "*" + names[9], file9); Set fileSet = fileMap.entrySet(); Iterator iter = fileSet.iterator(); // 取当前系统路径E:\Tomcat5\webapps\strutsUpload\ 其中strutsUpload为当前context String filePath = this.getServlet().getServletContext().getRealPath("/"); // 保存文件的文件夹 File savePath = new File(filePath + "UploadFiles\\"); filePath = filePath+ "UploadFiles\\"; if (!savePath.exists()) { savePath.mkdir(); } while (iter.hasNext()) { Map.Entry unit = (Map.Entry) iter.next(); String key = (String) unit.getKey(); FormFile file = (FormFile) unit.getValue(); //文件大小符合要求,且是图片文件 if ((file.getFileSize() >= 1)&& DealPhoto.isPhoto(file)) { //图片类别 String photoType = key.substring(key.indexOf("*") + 1, key .lastIndexOf("*")); //图片描述 String photoName = key.substring(key.lastIndexOf("*") + 1, key .length()); //存数据库操作,在数据库中保存文件的名称,类型,及在服务器上的相对路径 // //判断是否重名 if(DealPhoto.isFileExist(file.getFileName(),filePath)) DealPhoto.rename(file.getFileName(),filePath); try { InputStream stream = file.getInputStream();// 把文件读入 // 建立一个上传文件的输出流 OutputStream bos = new FileOutputStream(filePath+file.getFileName()); int bytesRead = 0; byte[] buffer = new byte[8192]; while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) { bos.write(buffer, 0, bytesRead);// 将文件写入服务器 } bos.close(); stream.close(); } catch (Exception e) { e.printStackTrace(); } } } return mapping.findForward("uploaded"); //还有其他可以改正的地方,如错误信息提示,把照片处理函数放到一个公用类,写文件操作等 //可以随便转载,请保留出自http://www.javaresearch.org 作者anEngineer } }
六。照片处理类文件
