新建文件taglibs.ftl内容
<#macro basePath><#if springMacroRequestContext.getContextPath()=="/"><#else>${springMacroRequestContext.getContextPath()}</#if></#macro>
<#global contextPath><@basePath/></#global> 这句就是精华
在你的ftl文件中引入
<#import "/spring.ftl" as spring />
<#include "/common/taglibs.ftl" /> 注意： <#macro basePath> 这段判断了没有项目跟目录的情况， 例如只有个 / 这种场景，
只要在其它文件里 ${contextPath} 就可以获取根目录了。 跟重要的是taglibs.ftl里可以引入更多的 tag 例如struts tld 样式公用jquery.js等东西。
网上说了很多方式在ftl里用 ${request.conextPath} ${Request.conextPath} 之类的我试了都没有作用
我觉得应该用springMacroRequestContext来读取request的方法， 不是获取属性值哦。
除此之外还可以定义宏 用import的方式导入文件
另外我附上spring.ftl 希望可以对您理解在freemark里使用spring标签有所帮助

<#-- * spring.ftl * * This file consists of a collection of FreeMarker macros aimed at easing * some of the common requirements of web applications - in particular * handling of forms. * * Spring's FreeMarker support will automatically make this file and therefore * all macros within it available to any application using Spring's * FreeMarkerConfigurer. * * To take advantage of these macros, the "exposeSpringMacroHelpers" property * of the FreeMarker class needs to be set to "true". This will expose a * RequestContext under the name "springMacroRequestContext", as needed by * the macros in this library. * * @author Darren Davison * @author Juergen Hoeller * @since 1.1 --> <#--
* message * * Macro to translate a message code into a message. --> <#macro message code>${springMacroRequestContext.getMessage(code)}</#macro> <#--

Can be called multiple times * within a form to bind to multiple command objects and/or field names. * * This macro will participate in the default HTML escape setting for the given * RequestContext.
