在spring MVC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>

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

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

<!---Action Definition-->
<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

login.stylesheetLocation=/WEB-INF/xsl/loginInfo.xsl

login.root=loginInfos
6。定义loginInfo.xsl文件
<?xml version="1.0" encoding="GBK"?>
<xsl:stylesheet

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>
