struts2 fileupload.jar

smartupload.jar

若是Servlet的话就可以用fileupload，Struts2有自己的上传工具

public class FileBiz {
	
	public void upload(HttpServletRequest request,String uploadPath) {
		SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");
		File tmpDir = new File("d:\\temp"); //初始化上传文件的临时存放目录,必须是绝对路径
		try {
			if (ServletFileUpload.isMultipartContent(request)) {
				DiskFileItemFactory factory = new DiskFileItemFactory();
				//指定在内存中缓存数据大小,单位为byte,这里设为1Mb
				factory.setSizeThreshold(1 * 1024 * 1024); 
				//设置一旦文件大小超过getSizeThreshold()的值时数据存放在硬盘的目录
				factory.setRepository(tmpDir); 
				ServletFileUpload sfu = new ServletFileUpload(factory);
				 // 指定单个上传文件的最大尺寸,单位:字节，这里设为5Mb
				sfu.setFileSizeMax(5 * 1024 * 1024);
				//指定一次上传多个文件的总尺寸,单位:字节，这里设为10Mb
				sfu.setSizeMax(10 * 1024 * 1024); 
				sfu.setHeaderEncoding("UTF-8"); //设置编码，因为我的jsp页面的编码是utf-8的
				FileItemIterator fii = sfu.getItemIterator(request);// 解析request请求
				uploadPath = uploadPath + "upload\\"; // 选定上传的目录此处为当前目录
				if (!new File(uploadPath).isDirectory()){
					new File(uploadPath).mkdirs(); //选定上传的目录此处为当前目录，没有则创建
				}
				
				int index = 0;
				while (fii.hasNext()) {
					FileItemStream fis = fii.next();// 从集合中获得一个文件流
					if (!fis.isFormField() && fis.getName().length() > 0) {// 过滤掉表单中非文件域
						String fileName = fis.getName().substring(
								fis.getName().lastIndexOf("."));// 获得上传文件的文件名
						fileName = sdf.format(new Date())+"-"+index+fileName;
						BufferedInputStream in = new BufferedInputStream(fis.openStream()); 
						BufferedOutputStream out = new BufferedOutputStream(
								new FileOutputStream(new File(uploadPath + "\\" + fileName)));
						Streams.copy(in, out, true); // 开始把文件写到你指定的上传文件夹
						index++;
					}
				}

			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
