（1）
（2）配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>

  <servlet-mapping>
    <servlet-name>springMvc</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>

</web-app>

（3）配置applicationContext.xml文件

<?xml version="1.0" encoding="UTF-8"?>

    <aop:aspectj-autoproxy proxy-target-class="true" />
    <!-- 自动扫描dao和service包(自动注入) -->
      <context:component-scan base-package="com.lmy.freemarker.controller" />

     <!-- freemarker的配置 -->  
    <bean id="freemarkerConfigurer"   class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">  
        <property name="templateLoaderPath" value="/WEB-INF/" />

            </props>  
        </property>  
    </bean> 

    <!-- FreeMarker视图解析 如返回userinfo。。在这里配置后缀名ftl和视图解析器。。 -->  
    <bean id="viewResolver"  
        class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">  
        <property name="viewClass"

    <bean id="multipartResolver"  class="org.springframework.web.multipart.commons.CommonsMultipartResolver"   p:defaultEncoding="UTF-8" /> 
    <!-- 添加注解驱动 -->  

  </beans>

（4）配置spring-mvc.xml文件

<beans xmlns="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"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 
    <context:property-placeholder location="classpath:resources.properties"/> -->

    <!-- 开启controller注解支持 -->
    <!-- 注意事项请参考：http://jinnianshilongnian.iteye.com/blog/1762632 -->
    <context:component-scan base-package="com.lmy.freemarker.controller" use-default-filters="false">
        <context:include-filter type="annotation"
                                expression="org.springframework.stereotype.Controller"/>
        <context:include-filter type="annotation"
                                expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
    </context:component-scan>

    <mvc:annotation-driven>
    </mvc:annotation-driven>

    <!-- 当在web.xml 中   DispatcherServlet使用 <url-pattern>/</url-pattern> 映射时，能映射静态资源 -->
    <mvc:default-servlet-handler/>

    <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
    <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>

     <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器-->
            </list>
        </property>
    </bean>
    <bean id="multipartResolver"  class="org.springframework.web.multipart.commons.CommonsMultipartResolver"   p:defaultEncoding="UTF-8" /> 
</beans>

（5）RichFreeMarkerView.java中的代码

package com.lmy.freemarker.controller;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.web.servlet.view.freemarker.FreeMarkerView;

public class RichFreeMarkerView extends FreeMarkerView {

    public static final String CONTEXT_PATH = "base";

    @SuppressWarnings("unchecked")
    protected void exposeHelpers(Map model, HttpServletRequest request)
            throws Exception {
        super.exposeHelpers(model, request);
        model.put(CONTEXT_PATH, request.getContextPath());
    }
}

（6）controller层（简单写了点逻辑）

package com.lmy.freemarker.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/from")
public class TestFreemarkerController {

    @RequestMapping("/query")
    public String TestFreemarker(ModelMap modelMap){
        String mes="你好！";
        String mes1="你好啊！";
        int a=2;
        modelMap.put("a",a);
        modelMap.put("mes", mes);
        modelMap.put("mes1", mes1);
        return "MyJsp";

    }

}

（7）页面

<!DOCTYPE html>

  <head>
    <title>index.html</title>

    <meta name="keywords" content="keyword1,keyword2,keyword3">
    <meta name="description" content="this is my page">
