Maven+SpringMVC+Freemarker入门Demo
1 参考http://blog.csdn.net/haishu_zheng/article/details/51490299,用第二种方法创建一个名为mavenspringmvcfreemarker的Maven工程。
2 文件目录结构如下图所示
3 在pom.xml中添加springmvc和freemarker的依赖包,添加完之后的完整内容为

4 web.xml中的完整内容为

5 spring-servlet.xml中的完整内容为:
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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.xsd
- http://www.springframework.org/schema/context
- http://www.springframework.org/schema/context/spring-context-3.0.xsd">
- <context:component-scan base-package="com.demo" />
- <bean
- class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
- <bean
- class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
- <!-- 配置Freemarker属性文件路径 -->
- <bean id="freemarkerConfiguration"

- <!-- 配置freeMarker模板加载地址 -->
- <bean id="freemarkerConfig"
- class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
- <!-- 视图解析器在/WEB-INF/ftl/路径下扫描视图文件 -->
- <property name="templateLoaderPath" value="/WEB-INF/ftl/" />
- <property name="freemarkerVariables">

- <!-- 给视图解析器配置优先級,你可以给之前jsp视图解析器的值配为2 -->
- <property name="order" value="1" />
- </bean>
- </beans>
注意:web.xml中,有个<servlet-name>为spring,所以这个文件起名为spring-servlet.xml。这样,程序自动会去加载spring-servlet.xml。也就说<xxx>-servlet.xml中的<xxx>必须与<servlet-name>的值完全对应。
不对应当然也可以,但是要在web.xml中显示指定加载。
比如:把spring-servlet.xml改名为applicationContext.xml,则要在web.xml中的</servlet-class>下方加代码:
- <init-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>/WEB-INF/applicationContext.xml</param-value>
- </init-param>
6 freemarker.properties中的完整内容为
- tag_syntax=auto_detect
- template_update_delay=2

- output_encoding=UTF-8
- locale=zh_CN
- date_format=yyyy-MM-dd
- time_format=HH:mm:ss
- datetime_format=yyyy-MM-dd HH\:mm\:ss
7 StudentController.java中的完整代码为:
- package com.demo.controller;
- import org.springframework.stereotype.Controller;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.ui.Model;
- @Controller
- public class StudentController {
- @RequestMapping("/helloWorld")
- public String helloWorld(Model model) {
- String word0 = "Hello ";
- String word1 = "World!";
- //将数据添加到视图数据容器中
- model.addAttribute("word0",word0);
- model.addAttribute("word1",word1);
- return "Hello.ftl";
- }
- }
8 Hello.ftl中的完整代码为:
- <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

9 将mavenspringmvcfreemarker添加进Tomcat 7中并运行
在浏览器中输入
http://localhost:8080/mavenspringmvcfreemarker/helloWorld
显示结果为
