ftp远程上传即读取文件

上传private void upload(File srcFile, String destFileURL) throws Exception {      FileSystemManager manager;      try {          manager = VFS.getManager();          FileObject srcFileObject = manager.resolveFile(srcFile, "");          FileObject destFileObject = manager.resolveFile(destFileURL);//这个是ftp地址          FileUtil.copyContent(srcFileObject, destFileObject);//在远程地址空间上复制目标文件      } catch (Exception e) {          e.printStackTrace();      }  }//远程ftp读取读取URL u=new URL(url);//这个是ftp文件完整地址 URLConnection urlconn=u.openConnection(); urlconn.getInputStream();//获得InputStream流。下面可以针对不同的文件格式，对其进行不同的包装。//如excel文件//xlsxOPCPackage opc = OPCPackage.open(urlconn.getInputStream());xwb = new XSSFWorkbook(opc);//xlsPOIFSFileSystem pf = new POIFSFileSystem(urlconn.getInputStream());HSSFWorkbook wb = new HSSFWorkbook(pf);
