项目结构图

废话不多说，集成步骤：

1.web.xml spring-mvc配置

<?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">

<welcome-file-list>

<welcome-file>upload.jsp</welcome-file>

</welcome-file-list>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:com/springfreemark/config/spring/spring-core.xml</param-value>

</context-param>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<servlet>

<servlet-name>spring-mvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:com/springfreemark/config/spring/springmvc-servlet.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet>

<description>This is the description of my J2EE component</description>

<display-name>This is the display name of my J2EE component</display-name>

<servlet-name>FreekMarkerServlet</servlet-name>

<servlet-class>com.springfreemark.web.servlet.FreekMarkerServlet</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>spring-mvc</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

<servlet-mapping>

<servlet-name>FreekMarkerServlet</servlet-name>

<url-pattern>*.ftl</url-pattern>

</servlet-mapping>

</web-app>

2. spring-mvc 配置文件

<?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: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-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx.xsd">

<context:component-scan base-package="com.springfreemark.web" />

<mvc:annotation-driven />

<mvc:default-servlet-handler />

<bean id="fmXmlEscape"

class="freemarker.template.utility.XmlEscape" />

<bean id="freemarkerConfig"

class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">

<property name="templateLoaderPath" value="/WEB-INF/ftl/" />

<property name="freemarkerVariables">

<map>

<entry key="xml_escape" value-ref="fmXmlEscape" />

<entry key="webRoot" value="${webRoot}"></entry>

<entry key="jsRoot" value="${jsRoot}"></entry>

</map>

</property>

<!-- FreeMarker默认每隔5秒检查模板是否被更新，如果已经更新了，就会重新加载并分析模板。但经常检查模板是否更新可能比较耗时。如果你的应用运行在生产模式下，而且你预期模板不会经常更新，

则可以将更新的延迟时间延长至一个小时或者更久。可以通过为freemarkerSettings属性设置template_update_delay达到这一目的 -->

<property name="freemarkerSettings">

<props>

<prop key="template_update_delay">3600</prop>

<prop key="tag_syntax">auto_detect</prop>

<prop key="default_encoding">UTF-8</prop>

<prop key="output_encoding">UTF-8</prop>

<prop key="locale">zh_CN</prop>

<prop key="date_format">yyyy-MM-dd</prop>

<prop key="time_format">HH:mm:ss</prop>

<prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>

<prop key="number_format">#</prop>

<prop key="classic_compatible">true</prop>

<prop key="template_exception_handler">html_debug</prop>

</props>

</property>

</bean>

<bean id="viewResolver"

class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">

<property name="viewClass"

value="org.springframework.web.servlet.view.freemarker.FreeMarkerView" />

<property name="viewNames" value="*.ftl" />

<property name="contentType" value="text/html; charset=utf-8" />

<property name="cache" value="true" />

<property name="suffix" value="" />

<property name="order" value="2" />

</bean>

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

<property name="maxUploadSize" value="104857600"/>

<property name="maxInMemorySize" value="4096"/>

</bean>

</beans>

3.DataController.java 逻辑控制

package com.springfreemark.web.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Component;

import org.springframework.web.bind.annotation.RequestMapping;

@Component

@RequestMapping("/main/")

public class DataController extends BaseController {

@RequestMapping("go")

public String exec(HttpServletRequest request){

request.getSession().setAttribute("name", "springfreemark集成成功");

return "/demo.ftl";

输入地址 : http://localhost:8080/SpringFreeMarker/main/go

ok 大功告成
