修改后的XML文件无法保存java

Question

我正在制作一个Web应用程序，我需要创建一个日志。我将此日志存储为xml文件。

这些是我的路径：

log.xml - ＆gt; org.codealizer.quizme.resources

Servlet - ＆gt; org.codealizer.quizme.servlets

当我的应用程序运行时，它会给我一个成功的结果，但不会修改xml文件。

这是我修改xml文件的代码：

private void createLog(HttpServletRequest request,
        HttpServletResponse response, PrintWriter out) {
    String ipAddress = request.getRemoteAddr();
    int port = request.getRemotePort();
    String clientInformation = request.getHeader("user-agent");

    try {
        DocumentBuilderFactory factory = DocumentBuilderFactory
                .newInstance();
        DocumentBuilder dBuilder = factory.newDocumentBuilder();

        Document doc = dBuilder.parse(getClass().getResourceAsStream(
                "/org/codealizer/quizme/resources/log.xml"));

        doc.getDocumentElement().normalize();

        Node log = doc.getFirstChild();

        Element item = doc.createElement("item");

        Element time = doc.createElement("time");
        time.appendChild(doc.createTextNode("" + System.currentTimeMillis()));
        item.appendChild(time);

        Element access = doc.createElement("access");
        access.appendChild(doc.createTextNode(getClass().getName()));
        item.appendChild(access);

        Element address = doc.createElement("address");
        address.appendChild(doc.createTextNode(ipAddress + ":" + port));
        item.appendChild(address);

        Element client = doc.createElement("client");
        client.appendChild(doc.createTextNode(clientInformation));
        item.appendChild(client);

        log.appendChild(item);

        // Update
        TransformerFactory transformerFactory = TransformerFactory
                .newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        DOMSource source = new DOMSource(doc);
        StreamResult result = new StreamResult(getClass().getResource(
                "/org/codealizer/quizme/resources/log.xml").getFile());

        // Output to console for testing
        // StreamResult result = new StreamResult(System.out);

        transformer.transform(source, result);

    } catch (SAXException | IOException | ParserConfigurationException
            | TransformerException e) {
        out.println(e.getMessage());
    }

这是我当前的log.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<log></log>

有人可以帮我解决这个问题吗？很多：）
