freemarker的配置思路

来源：互联网发布：包装刀模软件编辑：程序博客网时间：2024/05/29 07:30

首先搭建ssm框架，导入freemarker 的jar包，如图所示：

1.spring+springMVC的配置这里不再赘述，这里只是演示不连接数据库

web.xml将.action的影响换成.html

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <display-name></display-name>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list>  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>/WEB-INF/bean.xml</param-value>  </context-param>  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <servlet>    <servlet-name>springmvc</servlet-name>    <servlet-class>            org.springframework.web.servlet.DispatcherServlet        </servlet-class>    <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>springmvc</servlet-name>    <url-pattern>*.html</url-pattern>        <!-- 这里-->  </servlet-mapping></web-app>

2.产生的影响在原来action包中的文件

把原来的action改成了html，我个人理解，可能是在地址栏上写html更符合常理。

package it.com.action;import java.util.ArrayList;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpSession;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;@Controllerpublic class Test {@RequestMapping(value="test.html")    //这里的action都换成了htmlpublic ModelAndView test(HttpSession session){List list = new ArrayList();list.add("a1");list.add("a2");list.add("a3");list.add("a9");session.setAttribute("list", list);return new ModelAndView("index");}@RequestMapping(value="login.html")public ModelAndView login(HttpServletRequest request){String username = request.getParameter("username");String userpwd = request.getParameter("userpwd");if(username.equals("abc")&&userpwd.equals("111")){return new ModelAndView("x1");}else {return new ModelAndView("x2");}}}

3.springMVC的配置文件，这里要标明代替原来jsp页面的ftl文件路径

<?xml version="1.0" encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:component-scan base-package="it.com.*"></context:component-scan><bean id="viewResolver"        class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">      <property name="suffix">          <value>.ftl</value>      </property>      <property name="contentType" value="text/html;charset=UTF-8"></property>  </bean>  <bean id="freemarkerConfig"        class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">      <property name="templateLoaderPath" value="/WEB-INF/templates/" />  <!--这里配置路径--></bean></beans>

4.templates中的文件都是静态的，就是讲原来jsp中关于java和servlet部分的影响删干净，纯净的html页面，当然freemarker有自己独立的语法，查api就是了

<html>  <head>  </head>  <body>    This is my JSP page. <br>    <table border="1">    <#list list as u>        <tr><td>${u}</td></tr>    </#list>    </table>    <form action="login.html">      <table>        <tr>           <td>用户名</td>           <td><input type="text" name="username"/></td>        </tr>        <tr>           <td>密码</td>           <td><input type="text" name="userpwd"/></td>        </tr>        <tr>          <td colspan="1"><input type="submit"  value="提交"/></td>        </tr>        </table>      </form>  </body></html>

总结：图一可以看到，将jsp转换成纯静态页面以后前后端是真正意义上的分离jsp就是java servlet page，前端就可以专注页面的设计了。其次，将页面文件放在WEB-INF文件下，地址栏是无法直接访问的，（相对）很安全！
