5.建一个HelloFreeMarkerServlet:

packagedemo;

importjava.io.IOException;

importjava.io.PrintWriter;

importjava.util.HashMap;

importjava.util.Map;

importjavax.servlet.ServletException;

importjavax.servlet.http.HttpServlet;

importjavax.servlet.http.HttpServletRequest;

importjavax.servlet.http.HttpServletResponse;

importfreemarker.template.Configuration;

importfreemarker.template.Template;

importfreemarker.template.TemplateException;

@SuppressWarnings("serial")

publicclassHelloFreeMarkerServlet extendsHttpServlet

{

??? privateConfiguration cfg= null;

??? @Override

??? publicvoidinit() throwsServletException

??? {

??????? // FreeMarker程序入口点

??????? cfg= newConfiguration();

??????? // 初始化 Servlet 上下文(第二参数为ServletContext的相对路径,null代表当前网站根路径，相对路径)

??????? cfg.setServletContextForTemplateLoading(this.getServletContext(), null);??????

??? }

??? @SuppressWarnings("unchecked")

??? @Override

??? protectedvoiddoPost(HttpServletRequest req, HttpServletResponse resp)

??????????? throwsServletException, IOException

??? {

??????? // 模板文件会根据key，读取value

??????? Map root = new HashMap ();

??????? root.put("message", "hello!");

??????? root.put("username", "SSimpleframe and freemarker lover.");

?? ?????Template t = cfg.getTemplate("/templates/test.ftl");

??????? resp.setCharacterEncoding("utf-8");

??????? PrintWriter out = resp.getWriter();

??????? try

??????? {

??????????? t.process(root, out);

??????? } catch(TemplateException e)

??????? {

??????????? e.printStackTrace();

??????? }

??? }

??? @Override

??? protectedvoiddoGet(HttpServletRequest req, HttpServletResponse resp)

??????????? throwsServletException, IOException

??? {

??????? this.doPost(req, resp);

??? }

}

6.web.xml中的相应配置:

<?xmlversion="1.0" encoding="UTF-8"?>

<web-appxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"

??? xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

??? xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

??? id="WebApp_ID" version="2.5">

??? <servlet>

??????? <servlet-name>testServlet</servlet-name>

??????? <servlet-class>demo.HelloFreeMarkerServlet</servlet-class>

??? </servlet>

??? <servlet-mapping>

??????? <servlet-name>testServlet</servlet-name>

??????? <url-pattern>/hello.do</url-pattern>

??? </servlet-mapping>

??? <filter>

?????? <filter-name>actionFilter</filter-name>

??? ??? <filter-class>net.Simpleframework.web.page.PageFilter</filter-class>

??? </filter>

??? <filter-mapping>

?????? <filter-name>actionFilter</filter-name>

?????? <url-pattern>*. jsp </url-pattern>

??? </filter-mapping>??

??? <filter-mapping>

?????? <filter-name>actionFilter</filter-name>

?????? <url-pattern>*.do</url-pattern>

??? </filter-mapping>

??? <listener>

??? <listener-class>net.Simpleframework.web.page.PageEventAdapter</listener-class>

??? </listener>

</web-app>

7. 申明组件元数据定义，需要对应于拦截的hello, hello.xml 文件如下：

<?xmlversion="1.0" encoding="UTF-8"?>

<pagexmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

? xsi:noNamespaceSchemaLocation="/xsd/default/sSimple.xsd">

??? <responseCharacterEncoding> gbk </responseCharacterEncoding>

? <components>

??? <treename="demoTree1" containerId="demoTree1" handleClass="net.Simpleframework.example.MyTree"

????? width="240">

????? <treenodetext="Root" acceptdrop="true">

??????? <treenodetext="Node1" draggable="true" acceptdrop="true">

????????? <jsDblclickCallback>alert('Node1');</jsDblclickCallback>

??????? </treenode>

??????? <treenodetext="Node2" draggable="true" acceptdrop="true">

????????? <treenodetext="Node2_1" draggable="true" acceptdrop="true">

??????????? <jsDblclickCallback>alert('Node2_1');</jsDblclickCallback>

????????? </treenode>

????????? <treenodetext="Node2_2" draggable="true" acceptdrop="true">

????????? </treenode>

????????? <treenodetext="Node2_3" draggable="true" acceptdrop="true">

????????? </treenode>

??????? </treenode>

??????? <treenodetext="Node3" draggable="true" acceptdrop="true">

??????? </treenode>

??????? <treenodetext="Node4" draggable="true" acceptdrop="true">

??????? </treenode>

????? </treenode>

??? </tree>

??? <treename="demoTree2" containerId="demoTree2" checkboxes="true"

????? checkboxesThreeState="true" dynamicLoading="true" width="240">

????? <treenodetext="北京市"/>

????? <treenodetext="上海市"/>

?????? ***

??? </tree>
