首先目录结构如图  
![这里写图片描述][70]  
1.POM文件中添加包依赖  
注意spring-context-support的版本号与系统spring版本号一致

<dependency>
      <groupId>org.freemarker</groupId>
      <artifactId>freemarker</artifactId>
      <version>2.4.0</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context-support</artifactId>
      <version>4.1.2.RELEASE</version>
    </dependency>

2.application-context.xml 添加视图解析器

<?xml version="1.0" encoding="UTF-8"?>  
    <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" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd" default-lazy-init="true">  
          
        <mvc:annotation-driven />  
          
        <context:component-scan base-package="com.my.demo" />  
    
         <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">  
            <property name="templateLoaderPath" value="WEB-INF/" />  
            <property name="defaultEncoding" value="UTF-8" />  
         </bean>  
           
         <bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">  
            <property name="prefix" value="/"></property>    
            <property name="suffix" value=".html" />  
            <property name="contentType" value="text/html;charset=UTF-8" />  
            <property name="requestContextAttribute" value="rc" />  
         </bean> 
    
    </beans>

注意web.xml里的配置如下

<?xml version="1.0" encoding="UTF-8"?>
    <web-app 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_3_0.xsd" xmlns:web="http://java.sun.com/xml/ns/javaee" id="WebApp_ID" version="3.0" metadata-complete="true">
    
        <display-name>displayname</display-name>
    
        <servlet>
            <servlet-name>demo</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
             <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>/WEB-INF/classes/conf/application-context.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>demo</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    
    
    </web-app>

3.可以添加ftl模板文件 spring.ftl ，global.ftl是自定义指令

4.创建cotroller

package com.my.demo.web;
    
    import javax.servlet.http.HttpServletRequest;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class HelloWorldController {
    
        @RequestMapping("hello")
        public String loginFunction(HttpServletRequest request, Model model){
            System.out.println("controller start");
            model.addAttribute("book","234");
            System.out.println("controller end");
            return "hello";
        }
    
    }

5.创建hello.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>hello</title>
    </head>
    <body>
    hello ${book!}
    </body>
    </html>

访问localhost:8080/项目名/hello 就ok啦。
