import javax.servlet.http.HttpServletRequest;

public class FileInfo extends ActionForm {

private FormFile thisFile;

public FormFile getThisFile() {

return thisFile;

}

public void setThisFile(FormFile thisFile) {

this.thisFile = thisFile;

}

public ActionErrors validate(ActionMapping actionMapping,

HttpServletRequest httpServletRequest) {

/** @todo: finish this method, this is just the skeleton.*/

return null;

}

public void reset(ActionMapping actionMapping,

HttpServletRequest servletRequest) {

}

}

public class myupload extends Action {

public ActionForward execute(ActionMapping actionMapping,

ActionForm actionForm,

HttpServletRequest request,

HttpServletResponse response) throws

FileNotFoundException, IOException {

FileInfo fileInfo = (FileInfo) actionForm;

//获取上传文件

FormFile f=fileInfo.getThisFile();

InputStream is=f.getInputStream();

//将文件存入服务器上

String filename=request.getSession().getServletContext().getRealPath("/shangchuan/"+f.getFileName());

OutputStream os=new FileOutputStream(filename);

int x=0;

//优化流处理过程

byte[] buffer = new byte[8192];

while((x=is.read(buffer, 0, 8192))!=-1)

{

os.write(buffer,0,x);

}

os.close();

response.sendRedirect("jsp1.jsp");//根据实际情况跳转

return null;
