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[/code] 
http://www.springframework.org/schema/mvc[/code] 
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd[/code] 
http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd[/code] 
http://www.springframework.org/schema/util[/code] 
http://www.springframework.org/schema/util/spring-util-3.0.xsd"[/code] 
 

<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[/code] 
http://www.springframework.org/schema/aop 

http://www.springframework.org/schema/aop/spring-aop-3.0.xsd[/code] 
http://www.springframework.org/schema/tx 

http://www.springframework.org/schema/tx/spring-tx-3.0.xsd[/code] 
http://www.springframework.org/schema/util 

http://www.springframework.org/schema/util/spring-util-3.0.xsd[/code] 
http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd"[/code] 
</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!~.~
