freemarker 全局变量

场景：Spring MVC配备Freemarker全局变量，实现应用全路径

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" />
