SSH框架对比Jfinal框架-文件上传下载

SSH文件下载:
       File f = new File(filePath);
        if (!f.exists()) {
            response.sendError(404, "File not found!");
            return;
        }
        BufferedInputStream br = new BufferedInputStream(new FileInputStream( f));
        byte[] buf = new byte[1024];
        int len = 0;

        response.reset(); // 非常重要
        if (isOnLine) { // 在线打开方式
            URL u = new URL("file:///" + filePath);
            response.setContentType(u.openConnection().getContentType());
            response.setHeader("Content-Disposition", "inline; filename=" + f.getName());
        } else { // 纯下载方式
            response.setContentType("application/x-msdownload;charset=UTF-8");
            response.setHeader("Content-Disposition", "attachment; filename=" + f.getName(),"iso-8859-1");
        }
        OutputStream out = response.getOutputStream();
        while ((len = br.read(buf)) > 0)
            out.write(buf, 0, len);
        br.close();
        out.close();
Jfinal文件上传:
        List<UploadFile> files=null;
String path="attachFile/";
try {
files=getFiles(path,1024*1024*10,"UTF-8");
} catch (Exception e) {
renderText("总上传附件不能超过10M<a href='history.back();'>返回</a>");
e.printStackTrace();
}
        for(int i=0;i<files.size();i++){
   UploadFile uf=files.get(i);
    //拿到上传图片的后缀名称
    String suffix = uf.getFileName();
    if(suffix!=null){
int travel_id=travel.getNumber("id").intValue();
String[] filenames = suffix.split("\\.");
String suffixName = filenames[filenames.length-1];
String fileName=System.currentTimeMillis()+"_"+month+"."+suffixName;
uf.getFile().renameTo(new File(uf.getSaveDirectory()+fileName));
try {
AttachFile attachFile=new AttachFile();
attachFile.set("id", "T_ATTACHFILE_ID.nextval")
attachFile.save();
} catch (Exception e) {
//删除
                        uf.getFile().delete();
}
}
}
Jfinal文件下载:
        //getSession().getServletContext().getRealPath("/")+   flie.getStr("path_");
    File f = new File(basePath);
    if (!f.exists()) {
                //报错模板
        setAttr("title", "404");
     setAttr("message", "File not found!");
        render(consts.templateErr);
    }else{
        renderFile(f);
    }
