網絡文件需要使用輸入流來讀取
所以獲取網絡文件的時候要用getInputStream()，如果是本地文件可以用getFile()

小例子

        UrlResource urlResource = new UrlResource("http://www.slience.com/book.xml");
        System.out.println("urlResource.getFilename()="+urlResource.getFilename());
        System.out.println("urlResource.getDescription()="+urlResource.getDescription());
        SAXReader saxReader = new SAXReader();
        Document document = saxReader.read(urlResource.getInputStream());
        Element element = document.getRootElement();
        List list = element.elements();
        Iterator iterator = list.iterator();
        while(iterator.hasNext()) {
            Element element2 = (Element) iterator.next();
            System.out.println(element2.getName()+":"+element2.getText());
        }
