1、 新建WebProject，工程名称是SpringFreemarker；然后手动添加jar包，需要的jar包如下：

 

 

SpringFramework jar包下载地址：

 

http://ebr.springsource.com/repository/app/library/version/detail?name=org.springframework.spring&version=3.0.5.RELEASE

 

FreeMarker library下载地址：

 

http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.freemarker&version=2.3.15

 

当然你也可以去官方下载

 

2、 在web.xml中添加如下配置：

 

<!-- 加载Spring容器配置 -->

< listener >

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

</ listener >

<!-- 设置Spring容器加载配置文件路径 -->

< context-param >

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

< param-value > classpath*:applicationContext-*.xml</ param-value >

</ context-param >

 

< servlet >

< servlet-name > dispatcher</ servlet-name >

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

< init-param >

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

< param-value > /WEB-INF/dispatcher.xml</ param-value >

</ init-param >

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

</ servlet >

 

< servlet-mapping >

< servlet-name > dispatcher</ servlet-name >

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

</ servlet-mapping >

 

上面分别是添加Spring的监听器、以及配置Spring的配置文件、还有SpringMVC的控制器；

 

3、 在WEB-INF中添加文件dispatcher.xml，和web.xml中的对应。内容如下：

 

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

< beans xmlns ="http://www.springframework.org/schema/beans"

xmlns:mvc ="http://www.springframework.org/schema/mvc" xmlns:context ="http://www.springframework.org/schema/context"

xmlns:util ="http://www.springframework.org/schema/util" xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation ="http://www.springframework.org/schema/beans >

http://www.springframework.org/schema/beans/spring-beans-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/context

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

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

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

 

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

 

<!-- annotation的方法映射适配器

<bean id="handlerAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

-->

<!-- annotation默认的方法映射适配器 -->

< bean id ="handlerMapping" class ="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

 

< bean class ="org.springframework.web.servlet.view.InternalResourceViewResolver" >

< property name ="viewClass" value ="org.springframework.web.servlet.view.JstlView" />

</ bean >

 

</ beans >

 

 

上面是SpringMVC的基本配置

 

4、 在src中添加applicationContext-beans.xml，内容如下：

 

<? 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:aop ="http://www.springframework.org/schema/aop"

xmlns:tx ="http://www.springframework.org/schema/tx"

xmlns:util ="http://www.springframework.org/schema/util"

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/aop

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

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

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

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

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

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

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

</ beans >

 

里面可以添加一些bean的配置

 

5、 在src目录添加freemarker.properties配置文件，这个文件是freemarker一些常用的转换，内容如下：

 

tag_syntax=auto_detect

template_update_delay=2

default_encoding=UTF-8

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

 

6、 在dispatcher.xml中添加freemarker的配置，配置如下：

 

<!-- 设置freeMarker的配置文件路径 -->

< bean id ="freemarkerConfiguration" class ="org.springframework.beans.factory.config.PropertiesFactoryBean" >

< property name ="location" value ="classpath:freemarker.properties" />

</ bean >

 

<!-- 配置freeMarker的模板路径 -->

< bean id ="freemarkerConfig" class ="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer" >

<!--property name="freemarkerSettings" ref="freemarkerConfiguration"/-->

< property name ="templateLoaderPath" >

< value > /WEB-INF/ftl/</ value >

</ property >

< property name ="freemarkerVariables" >

< map >

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

</ map >

</ property >

</ bean >

 

< bean id ="fmXmlEscape" class ="freemarker.template.utility.XmlEscape" />

 

<!-- 配置freeMarker视图解析器 -->

< 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 ="prefix" value ="" />

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

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

</ bean >

 

上面最关键的就是freeMarker的视图解析器viewResolver的配置，viewClass是使用哪个视图解析器，这里是类路径；其他的和jsp的视图解析器都很类似。

 

7、 下面在WEB-INF中添加2个ftl模板，在WEB-INF添加ftl，然后添加hello.ftl/hi.ftl，内容分别是：

 

hello.ftl

 

< html >

< body >

< h1 > say hello ${name}</ h1 >< br />

${(1 == 1)?string("yes", "no")}

</ body >

</ html >

 

hi.ftl

 

< html >

< body >

< h1 > say hello ${name}</ h1 >< br />

${(1 != 1)?string("yes", "no")}

</ body >

</ html >

 

8、 添加Controller控制器，代码如下：

 

package com.hoo.controller;

 

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

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

 

/**

* <b>function:</b> FreeMarker示例控制器

* @author hoojo

* @createDate 2011-3-3 下午04:50:10

* @file HelloWorldController.java

* @package com.hoo.controller

* @project SpringFreemarker

* @version 1.0

*/

@Controller

@RequestMapping("/freeMarker" )

public class HelloWorldController {

 

@RequestMapping("/hello" )

public String sayHello(ModelMap map) {

System.out.println("say Hello ……" );

map.addAttribute("name" , " World!" );

return "/hello.ftl" ;

}

 

@RequestMapping("/hi" )

public String sayHi(ModelMap map) {

System.out.println("say hi ……" );

map.put("name" , "jojo" );

return "/hi.ftl" ;

}

 

@RequestMapping("/jsp" )

public String jspRequest(ModelMap map) {

System.out.println("jspRequest ……" );

map.put("name" , "jsp" );

return "/temp.jsp" ;

}

}

 

9、 添加index.jsp的测试链接或temp.jsp的内容：

 

index.jsp

 

< body >

< a href ="freeMarker/hello.do" > say hello</ a >< br />

< a href ="freeMarker/hi.do" > say hi</ a >< br />

< a href ="freeMarker/jsp.do" > jspRequest</ a >

</ body >

 

temp.jsp

 

< body >

< h3 > ${name }</ h3 >

</ body >

 

如果运行无错误，并输出正确的结果就整合成功！~.~
