求Struts文件上传下载

有没有人帮帮忙啊。[email protected]

解决方案 »

  1.   

    这是一篇关于《上传下载全攻略jspSmartUpload》
    http://bbs.itebook.net/viewthread.php?tid=81641
      

  2.   

    还有：
    http://blog.csdn.net/oliveyuganfei/archive/2004/11/08/172704.aspx原理是一样的，你自己琢磨！
      

  3.   

    我想知的是写SQL的那段。现在比较急啊，而我写的那个又出错了。真是没办法。所以想求一个源码。
      

  4.   

    作zip的话就可以传上去，
    public void updateDate(ByteArrayOutputStream byteOut)
        {
            
            ByteArrayInputStream byteIn = new ByteArrayInputStream(byteOut.toByteArray());
            Connection conn = null;
            try {
                Class.forName(driver).newInstance();
                conn = DriverManager.getConnection(url, username, password);
                ZipInputStream zip = new ZipInputStream(byteIn);
                InputStream in = (InputStream) zip;
                String sql = "UPDATE data SET content=? WHERE id=106;";
                PreparedStatement s = conn.prepareStatement(sql);
                s.setBinaryStream(1, byteIn, byteIn.available());
                s.executeUpdate();
               System.out.println("数据已经更新!");
            }catch (SQLException e){
                e.printStackTrace();
            }catch(ClassNotFoundException e){
                e.printStackTrace();
            }catch(Exception e){
                e.printStackTrace();
            }
        }
      

  5.   

    我自己在struts中有做过文件上传功能，我把代码给你看看了

    struts直接就支持文件上传的，它有file标记，和相应的获取办法，查查书吧《struts start stick》好象是这本书有

    写入路径的我已写完了。但不知用stream写入数据库的怎么做。就是说将文件写入数据库。最好有源码。分可以再加。大家帮帮忙啊。
