一、前言
这边基于springframework的mvc框架,并通过freemarker的ftl视图渲染文件返回数据,在spring文件中配置对应org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver视图解析类（freemarker-2.3.21.jar.rar的jar、pom文件下载）,完整Maven项目源码点击跳转spring4Mvc-freemarker的helloworld项目相关篇章
二、代码实例
1.web.xml配置如下
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"@b@ xmlns="http://java.sun.com/xml/ns/javaee"@b@ xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"@b@ id="WebApp_ID" version="3.0">@b@ <display-name>HelloWorldSpring</display-name>@b@@b@ <servlet>@b@ <servlet-name>spring-mvc</servlet-name>@b@ <servlet-class>@b@ org.springframework.web.servlet.DispatcherServlet@b@ </servlet-class>@b@ <load-on-startup>1</load-on-startup>@b@ </servlet>@b@@b@ <servlet-mapping>@b@ <servlet-name>spring-mvc</servlet-name>@b@ <url-pattern>/</url-pattern>@b@ </servlet-mapping>@b@@b@ <!-- Other XML Configuration -->@b@ <!-- Load by Spring ContextLoaderListener -->@b@ <context-param>@b@ <param-name>contextConfigLocation</param-name>@b@ <param-value>/WEB-INF/root-context.xml</param-value>@b@ </context-param>@b@@b@ <!-- Spring ContextLoaderListener -->@b@ <listener>@b@ <listener-class>org.springframework.web.context.ContextLoaderListener@b@ </listener-class>@b@ </listener>@b@</web-app>
2.spring-mvc-servlet.xml配置如下
<?xml version="1.0" encoding="UTF-8"?>@b@<beans xmlns="http://www.springframework.org/schema/beans"@b@ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"@b@ xmlns:p="http://www.springframework.org/schema/p"@b@ xmlns:context="http://www.springframework.org/schema/context"@b@ xmlns:mvc="http://www.springframework.org/schema/mvc"@b@ xsi:schemaLocation="http://www.springframework.org/schema/beans@b@ http://www.springframework.org/schema/beans/spring-beans-4.1.xsd @b@ http://www.springframework.org/schema/context@b@ http://www.springframework.org/schema/context/spring-context-4.1.xsd @b@ http://www.springframework.org/schema/mvc@b@ http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">@b@ @b@ <context:component-scan base-package="com.xwood.springmvc"/>@b@ @b@ <context:annotation-config/> @b@ @b@ <bean id="FreeMarkerConfigurer" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">@b@ <property name="templateLoaderPath" value="/WEB-INF/pages/"/>@b@ <property name="defaultEncoding" value="UTF-8"/>@b@ </bean>@b@ <bean id="FreeMarkerViewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">@b@ <property name="suffix" value=".ftl"/>@b@ <property name="contentType" value="text/html;charset=UTF-8"/> @b@ </bean>@b@ @b@ @b@</beans>
3.FreeMarkerController的代码
package com.xwood.springmvc;@b@import org.springframework.stereotype.Controller;@b@import org.springframework.web.bind.annotation.RequestMapping;@b@import org.springframework.web.servlet.ModelAndView;@b@ @b@ @b@@Controller @b@@RequestMapping("/freemark") @b@public class FreeMarkerController { @b@ @b@ @RequestMapping("/index") @b@ public ModelAndView index(){@b@ return new ModelAndView("hello3","content","欢迎访问小木人印象,网址:<a href=\"http://www.xwood.net/\">http://www.xwood.net/</a>"); @b@ }@b@}4.hello3.ftl模板内容如下
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" @b@ "http://www.w3.org/TR/html4/loose.dtd">@b@<html> @b@ <body>@b@ ${content}@b@ </body>@b@</html>5.访问http://localhost:8080/HelloSpringMVC/freemark/index效果如下所示
三、pom.xml文件
