Spring MVC配置(四)

以下是本人對Spring MVC View層AbstractXsltView的一個實現及使用:

1.AbstractXsltView的實現:

package com.sunfairs.northwind.servlet; import java.util.List; import java.util.Map; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.xml.transform.Source; import org.jdom.Document; import org.jdom.Element; import org.jdom.output.DOMOutputter; import org.springframework.web.servlet.view.xslt.AbstractXsltView; import org.w3c.dom.Node; public class SpringXsltResolver extends AbstractXsltView { @Override protected Node createDomNode(Map map, String root, HttpServletRequest request, HttpServletResponse response) throws Exception { Document document = new Document(); Element rootEle = new Element(root); document.setRootElement(rootEle); List words = (List) map.get("wordList"); for(int i=0;i<words.size();i++){ String word = (String) words.get(i); Element element = new Element("word"); element.setText(word); rootEle.addContent(element); } return new DOMOutputter().output(document); } @Override protected Source createXsltSource(Map map, String root, HttpServletRequest request, HttpServletResponse response) throws Exception { return null; } }

2.AbstractController的實現:

package com.sunfairs.northwind.servlet; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.log4j.Logger; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; public class XsltViewServlet extends AbstractController { private static final Logger logger = Logger.getLogger(XsltViewServlet.class); private String viewName; public String getViewName() { return viewName; } public void setViewName(String viewName) { this.viewName = viewName; } @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { Map map = new HashMap(); List wordList = new ArrayList(); wordList.add("Hello!"); wordList.add("Hi!"); wordList.add("這是一段英文對話，意思是:"); wordList.add("你好!"); wordList.add("你好!"); map.put("wordList", wordList); return new ModelAndView(this.getViewName(),map); } }

3.web.xml的配置:

<servlet> <servlet-name>viewServlet</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>viewServlet</servlet-name> <url-pattern>*.po</url-pattern> </servlet-mapping>

4.viewServlet-servlet.xml的配置:

<bean id="viewResolver" class="org.springframework.web.servlet.view.BeanNameViewResolver"/> <bean id="servletHandlerAdapter" class="org.springframework.web.servlet.handler.SimpleServletHandlerAdapter"/> <bean id="controllerHandlerAdapter" class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> <bean id="beanMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="xslt.po">xsltViewController</prop> </props> </property> </bean> <bean id="xsltView" class="com.sunfairs.northwind.servlet.SpringXsltResolver"> <property name="stylesheetLocation"> <value>index.xsl</value> </property> <property name="root"> <value>wordList</value> </property> </bean> <bean id="xsltViewController" class="com.sunfairs.northwind.servlet.XsltViewServlet"> <property name="viewName"> <value>xsltView</value> </property> </bean>
