Spring MVC配置Freemarker全局变量，实现应用全路径

<context:property-placeholder location="classpath:config.properties" ignore-unresolvable="true"/>

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

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