从servlet写入XML文件
从servlet写入XML文件
提问于 2016-07-26 10:06:43
我试图将从表单中获取的一些数据写入XML文件，每次我希望创建新文件和写入数据时，我希望将这些文件存储在特定的文件夹中--这就是我尝试过的。我想补充一下，我通过httpRequest收到的任何东西都是成功的
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
String hostIPAddress=request.getParameter("hostIPAddress");
String destinationIPAddressTool1=request.getParameter("IPtool1");
String destinationIPAddressTool2=request.getParameter("IPtool2");
String root="root";
String hostIPElement="Host-IP";
String tool1Element="Tool-1";
String tool2Element="Tool-2";
if(destinationIPAddressTool1 == null)
{
destinationIPAddressTool1="none";
}
if(destinationIPAddressTool2 == null)
{
destinationIPAddressTool2="none";
}
DocumentBuilderFactory documentBuilderFactory=DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = null;
try {
documentBuilder = documentBuilderFactory.newDocumentBuilder();
} catch (ParserConfigurationException e) {
e.printStackTrace();
}
Document document = documentBuilder.newDocument();
Element rootElement = document.createElement(root);
document.appendChild(rootElement);
Element em1 = document.createElement(hostIPElement);
em1.appendChild(document.createTextNode(hostIPAddress));
rootElement.appendChild(em1);
Element em2 = document.createElement(tool1Element);
em2.appendChild(document.createTextNode(destinationIPAddressTool1));
rootElement.appendChild(em2);
Element em3 = document.createElement(tool2Element);
em3.appendChild(document.createTextNode(destinationIPAddressTool2));
rootElement.appendChild(em3);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = null;
try {
transformer = transformerFactory.newTransformer();
} catch (TransformerConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(System.out);
try {
transformer.transform(source, result);
} catch (TransformerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

在这里，最后尝试一下，它应该能工作。
//将内容写入xml文件
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("file.xml"));
// Output to console for testing
// StreamResult result = new StreamResult(System.out);
