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

<!-- 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 -->
