1、定義表單，封裝id，firstName和lastName
<form:form modelAttribute="person">
<form:hidden path="id" />
<fieldset>
<div class="form-row">
<label for="firstName"><fmt:message key="person.form.firstName"/>:</label>
<span class="input"><form:input path="firstName" /></span>
</div>
<div class="form-row">
<label for="lastName"><fmt:message key="person.form.lastName"/>:</label>
<span class="input"><form:input path="lastName" /></span>
</div>
<div class="form-buttons">
<div class="button">
<input type="submit" id="save" name="_eventId_save" value="<fmt:message key="button.save"/>"/>?
<input type="submit" name="_eventId_cancel" value="Cancel"/>?
</div>
</div>
</fieldset>
</form:form>
2、提交到servlet後，調用構造xml的java方法：
try {
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
// root elements
Document doc = docBuilder.newDocument();
Element rootElement = doc.createElement("company");
doc.appendChild(rootElement);
// staff elements
Element staff = doc.createElement("Staff");
rootElement.appendChild(staff);
// set attribute to staff element
Attr attr = doc.createAttribute("id");
attr.setValue("1");
staff.setAttributeNode(attr);
// shorten way
// staff.setAttribute("id", "1");
// firstname elements
Element firstname = doc.createElement("firstname");
firstname.appendChild(doc.createTextNode("yong"));
staff.appendChild(firstname);
// lastname elements
Element lastname = doc.createElement("lastname");
lastname.appendChild(doc.createTextNode("mook kim"));
staff.appendChild(lastname);
// nickname elements
Element nickname = doc.createElement("nickname");
nickname.appendChild(doc.createTextNode("mkyong"));
staff.appendChild(nickname);
// salary elements
Element salary = doc.createElement("salary");
salary.appendChild(doc.createTextNode("100000"));
staff.appendChild(salary);
// write the content into xml file
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("d:\\person.xml"))；
transformer.transform(source, result);
System.out.println("File saved!");
} catch (ParserConfigurationException pce) {
pce.printStackTrace();
} catch (TransformerException tfe) {
tfe.printStackTrace();
}
3、構造完成：
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<company>
<staff id="1">
<firstname>yong</firstname>
<lastname>mook kim</lastname>
<nickname>mkyong</nickname>
<salary>100000</salary>
</staff>
</company>
