如果这样做程序要怎么样写?望有这样经验的朋友给出例子或代码,谢谢!!!
6 个解决方案
#1
String filePath = this.getServlet().getServletContext().getRealPath("/") ; //取得当前路径
InputStream stream = fileone.getInputStream() ; //把文件读入
ByteArrayOutputStream baos = new ByteArrayOutputStream() ;
/*
* 建立一个上传文件的输出流如果是linux系统请把"\\" 换成 "/"
*/
OutputStream bos = new FileOutputStream(filePath + fileone.getFileName()) ;
request.setAttribute("fileName",filePath + "/" + fileone.getFileName() ) ;
int bytesRead = 0 ;
byte[] buffer = new byte[8192] ;
while( (bytesRead = stream.read(buffer,0,8192) ) != -1 )
{
bos.write(buffer,0,bytesRead) ;
}
bos.close();
stream.close() ;
//上传文件完成
String oldurl= filePath + fileone.getFileName() ;
String newurl= filePath + "min_" + fileone.getFileName() ; //新的缩略图保存地址,这里就可以自己保存到数据库了
#2
我要如何获取下面Content-Disposition中的filename的值,因为我不知道你的fileone.getFileName()是怎么样实现的,能给出代码吗?谢谢!!!
再者我能怎样分割下面这段信息?

Content-Disposition: form-data; name="FILE1"; filename="C:\Documents and Settings\yuxizhou\桌面\test\332.TXT"
Content-Type: text/plain
String filePath = this.getServlet().getServletContext().getRealPath("/") ; //取得当前路径
InputStream stream = fileone.getInputStream() ; //把文件读入
ByteArrayOutputStream baos = new ByteArrayOutputStream() ;
/*
* 建立一个上传文件的输出流如果是linux系统请把"\\" 换成 "/"
*/
OutputStream bos = new FileOutputStream(filePath + fileone.getFileName()) ;
request.setAttribute("fileName",filePath + "/" + fileone.getFileName() ) ;
int bytesRead = 0 ;
byte[] buffer = new byte[8192] ;
while( (bytesRead = stream.read(buffer,0,8192) ) != -1 )
{
bos.write(buffer,0,bytesRead) ;
}
bos.close();
stream.close() ;
//上传文件完成
String oldurl= filePath + fileone.getFileName() ;
String newurl= filePath + "min_" + fileone.getFileName() ; //新的缩略图保存地址,这里就可以自己保存到数据库了

如果你用STRUTS的话,可以直接用他的上传文件类库
import org.apache.struts.upload.*;
import org.apache.struts.upload.*;

我们没有用框架,请给出分割的方法,谢谢!!!
