Question

我的java类中有一个方法，它下载一个XML文件并返回一个org.w3c.dom.Document对象。

我想从这个java servlet类中获取这个XML，但是无法弄清楚如何。

我试过了：

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {


        Document document = Allmethods.getXML();

        response.setContentType("text/xml;charset=UTF-8");
        response.setHeader("Cache-Control", "no-cache");
        response.getWriter().write(document);

    }

但它不起作用，因为printwriter不适用于文档对象。我该如何存档？

我成功地听了@Jim Garrison的提示。

Document document = Allmethods.getXML();

        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer transformer = tf.newTransformer();
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");

        StringWriter writer = new StringWriter();
        transformer.transform(new DOMSource(document), new StreamResult(writer));
        String output = writer.getBuffer().toString();

        response.setContentType("text/xml;charset=UTF-8");
        response.setHeader("Cache-Control", "no-cache");
        response.getWriter().write(output);

在Servlet中执行XML
