1. 按照“ 用JBuilder2005开发spring MVC应用”一文建立基本的spring应用

2. 增加JDOM、Dom4J类库

3. 源文件如下,详细解释请看spring参考文档

/src/xslt/HomePageController.java

package xslt;

import java.util.*;

import javax.servlet.http.*;

import org.apache.commons.logging.*;

import org.springframework.web.servlet.*;

import org.springframework.web.servlet.mvc.*;

public class HomePageController extends AbstractController {

/** Logger for this class and subclasses */

protected final Log logger = LogFactory.getLog(getClass());

public ModelAndView handleRequestInternal(

HttpServletRequest req,

HttpServletResponse resp) throws Exception {

public ModelAndView handleRequest(HttpServletRequest request,

HttpServletResponse response) throws

ServletException, IOException {

Map map = new HashMap();

List wordList = new ArrayList();

wordList.add("hello");

wordList.add("world");

map.put("wordList", wordList);

return new ModelAndView("home", map);

}

/src/xslt/HomePage.java

package xslt;

import java.util.*;

import javax.servlet.http.*;

import org.jdom.Element;

import org.jdom.output.*;

import org.springframework.web.servlet.view.xslt.*;

import org.w3c.dom.*;

// imports omitted for brevity

public class HomePage extends AbstractXsltView {

protected Node createDomNode(

Map model, String rootName, HttpServletRequest req,

HttpServletResponse res

) throws Exception {

org.jdom.Document doc = new org.jdom.Document();

Element root = new Element(rootName);

doc.setRootElement(root);

List words = (List) model.get("wordList");

for (Iterator it = words.iterator(); it.hasNext(); ) {

String nextWord = (String) it.next();

Element e = new Element("word");

e.setText(nextWord);

root.addContent(e);

}

// convert JDOM doc to a W3C Node and return

return new DOMOutputter().output(doc);

}
