在springMVC框架中显示xml视图

举一个很简单的例子，用户在登陆窗口中输入用户名和密码，提交以后以xml的方式显示你填写的内容，

具体步骤如下：
1。配置web.xml文件
<servlet>
<servlet-name>login</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>login</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
2。配置login.xml文件
<bean id="viewResolver"

class="org.springframework.web.servlet.view.ResourceBundleViewResolver">
      <property name="basename">
        <value>views</value>
      </property>
</bean>


<bean id="urlMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
  <prop key="/login.htm">LoginAction</prop>

</props>
</property>
</bean>


<bean id="LoginAction"
class="LoginAction">
<property name="commandClass">
<value>LoginInfo</value>
</property>
<property name="fail_view">
<value>loginfail</value>
</property>
<property name="success_view">
<value>main</value>
</property>
</bean>
3。定义控制类loginAction.java和commandClass-->LoginInfo.java
<---------------------LoginAction---------------------------->
public class LoginAction extends SimpleFormController {

protected ModelAndView onSubmit(Object cmd, BindException ex)
throws Exception {
LoginInfo loginInfo = (LoginInfo) cmd;

  Map model = new HashMap();
  List list = new ArrayList();
  list.add(loginInfo);
  model.put("loginInfos", list);

return new ModelAndView("login", model);

}
<---------------------LoginAction---------------------------->
<---------------------LoginInfo---------------------------->
public class LoginInfo {
private String username;
private String password;

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }
}
<---------------------LoginInfo---------------------------->
4.定义自己的viewResolver--->LoginView
<---------------------LoginView---------------------------->
public class LoginView extends AbstractXsltView {
protected Node createDomNode(Map model, String rootName,
   HttpServletRequest request, HttpServletResponse response)
   throws Exception {

  Document doc = DocumentHelper.createDocument();
  Element root = doc.addElement(rootName);
  doc.setRootElement(root);
  List loginInfos = (List) model.get("loginInfos");
  for (Iterator it = loginInfos.iterator(); it.hasNext();) {
   LoginInfo info = (LoginInfo) it.next();
   Element a = root.addElement("loginInfo");
   a.addElement("username").addText(info.getUsername());
   a.addElement("password").addText(info.getPassword());

  }
  response.setContentType("text/xml");
  return new DOMWriter().write(doc);
}

}
<---------------------LoginView---------------------------->
5.定义views.properties文件
login.class=LoginView

xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<xsl:output method="xml" omit-xml-declaration="no"/>

<xsl:template match="/">

<loginInfos>

<xsl:for-each select="loginInfos/loginInfo">

<loginInfo>

<username>

<xsl:value-of select="username"/>

</username>

<password>

<xsl:value-of select="password"/>

</password>

</loginInfo>

</xsl:for-each>

</loginInfos>

</xsl:template>
</xsl:stylesheet>

7。定义index.html文件
<html>
<body>
<form method="POST" action="login.htm">
<p align="left">登录</p>
<br>
用户名:
<input type="text" name="username" >
<br>
密码 :
<input type="password" name="password" >
<br>
<p>
<input type="submit" value="提交" name="B1">
<input type="reset" value="重置" name="B2">
</p>
</form>
</body>
</html>
8。运行tomcat 预览：http://localhost:8080/xml/index.html
注：
views.properties放在classes文件夹。loginInfo.xsl放在/WEB-INF/xsl/文件夹。
index.html放在根目录下，xml文件放在/WEB-INF/下，其他的.class文件放在/WEB-INF/classes/下
需要的dom4j-1.6.jar、spring.jar放到/WEB-INF/lib下。
做完这一切，你就可以在浏览器里面测试结果了～！～
