一、新建WebProject，工程名稱是SpringFreemarker；而後手動添加jar包，須要的jar包以下：

SpringFramework jar包下載地址：

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

FreeMarker library下載地址：

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

固然你也能夠去官方下載

二、在web.xml中添加以下配置：

html

Java代碼 java

web
<listener> spring
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> spring-mvc
</listener> mvc
app
<context-param> jsp
<param-name>contextConfigLocation</param-name> 測試
<param-value>classpath*:applicationContext-*.xml</param-value> ui
</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>

上面分別是添加Spring的監聽器、以及配置Spring的配置文件、還有SpringMVC的控制器；

三、在WEB-INF中添加文件dispatcher.xml，和web.xml中的對應。內容以下：

Java代碼

<?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的方法映射適配器
<bean id="handlerAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
-->
<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

四、在src中添加applicationContext-beans.xml，內容以下：

Java代碼

<?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>

裏面能夠添加一些bean的配置

五、在src目錄添加freemarker.properties配置文件，這個文件是freemarker一些經常使用的轉換，內容以下：

Java代碼

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

六、在dispatcher.xml中添加freemarker的配置，配置以下：

Java代碼

<bean id="freemarkerConfiguration" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="location" value="classpath:freemarker.properties"/>
</bean>
<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<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"/>
<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>

上面最關鍵的就是freeMarker的視圖解析器viewResolver的配置，viewClass是使用哪一個視圖解析器，這裏是類路徑；其餘的和jsp的視圖解析器都很相似。

七、下面在WEB-INF中添加2個ftl模板，在WEB-INF添加ftl，而後添加hello.ftl/hi.ftl，內容分別是：

hello.ftl

Java代碼
