1. applicationContext.xml增加内容
<!– freemarker的配置 –>
<bean id="freemarkerConfigurer"
        class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="templateLoaderPath" value="/WEB-INF/jsp/" />
        <property name="defaultEncoding" value="UTF-8" />
        <property name="freemarkerSettings">
                <props>
                        <prop key="template_update_delay">10</prop>
                        <prop key="locale">zh_CN</prop>
                        <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>
                        <prop key="date_format">yyyy-MM-dd</prop>
                        <prop key="number_format">#.##</prop>
                </props>
        </property>
</bean>
<!– FreeMarker视图解析 如返回userinfo。。在这里配置后缀名ftl和视图解析器。。 –>
<bean id="viewResolver"
        class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <!– 下面的设置为解决base变量的获取 –>
        <property name="viewClass" value="com.useol.util.MyFreeMakerView" />
        <property name="suffix" value=".html" />
        <property name="contentType" value="text/html;charset=UTF-8" />
        <property name="exposeRequestAttributes" value="true" />
        <property name="exposeSessionAttributes" value="true" />
        <property name="exposeSpringMacroHelpers" value="true" />
</bean>
<bean id="messageSource"
        class="org.springframework.context.support.ResourceBundleMessageSource"
        p:basename="i18n/messages" />

2. 其中MyFreeMakerView类为解决springmvc和freemaker整合后，获取basepath，即context目录的问题，源码如下：
