swfupload

其实 swfupload 就是一个前端上传控件，和后端没什么联系，唯一的联系就是提交url 和 servlet 返回200，告诉你上传成功了

jsp：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>
<base href="<%=basePath%>">

servlet：

public class UploadFileServlet extends HttpServlet {

	private static final long serialVersionUID = 1L;

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {

		super.doGet(req, resp);
	}
	
	@Override
	protected void doPost(HttpServletRequest request, HttpServletResponse resp) {
		File fileList=null;
		try {
			
			//先判断存储文件的路径在不在，如果不存在，则创建该目录
			File dir=new File(Config.getUploadFilesDir());
			if(!dir.exists()){
				boolean b=dir.mkdirs();
			}
			
			//如果存储文件的“DB”不存在，则创建
			fileList=new File(Config.getFileNamesDB());
			if(!fileList.exists()){
				fileList.createNewFile();
			}

			DiskFileItemFactory factory = new DiskFileItemFactory();
			ServletFileUpload upload=new ServletFileUpload(factory);
			List<FileItem> items=upload.parseRequest(request);
//			System.out.println("items.size()===>"+items.size());

			Iterator iterator=items.iterator();
			while(iterator.hasNext()){

					if(!item.isFormField()){
						item.write(new File(Config.getUploadFilesDir()+item.getName()));
						TxtTools.appendContent(Config.getFileNamesDB(), item.getName());
						PrintWriter out=resp.getWriter();
						out.print("200");//告诉swfupload上传成功了，swfuplaod默认 收到200 为成功，其它返回请具体查看swfupload 的api
						out.close();
					}
			}
			
		} catch (Exception e) {
			e.printStackTrace();
		}finally{
			//
		}
	
		
	}

}
