JEECMS 2.4.2 之添加新的可扩展的ftl模版文件、自定义方法

Demo:

<@cms.CfgList isPage='1' league='0' recommend='0' lala='0' hot='1' memberId='0'  pageNo=pageNo count='4' orderBy=0 ;g>
                        <dl>
                            <dt><a href="/lala/LalaIndex.htm?fid=${g.id}" target="_blank"><img src="${g.logo}" /></a></dt>
                            <dd>
                                <span><a href="/lala/LalaIndex.htm?fid=${g.id}" target="_blank">${g.name!}</a></span>
                                <#assign al=action.getArtiByCfgId(g.id!0).list>
                                <#if al??>
                                    <#list al as ll>
                                        <#if ll.description?length gt 42>
                                            <a href="/lala/LaTopicDetail.htm?fid=${g.id}&aid=${ll.id}" target="_blank" style="text-decoration: none;">${ll.description?substring(0,41)}...</a>
                                        <#else>
                                            <a href="/lala/LaTopicDetail.htm?fid=${g.id}&aid=${ll.id}" target="_blank" style="text-decoration: none;">${ll.description!}</a>
                                        </#if>
                                    </#list>
                                </#if>
                            </dd>
                        </dl>
                    </@cms.CfgList>

上面的<@cms.CfgList...>之所以可以调用是因为在freemarker.properties:

auto_import="/WEB-INF/ftl_lib/ponyjava.com/index.ftl" as p, "/WEB-INF/ftl_lib/fcms/index.ftl" as cms

接下来顺藤摸瓜的跟进去看看index.ftl 找到相应的宏定义(macro)

<#--
球迷会列表(自定义内容)
    team:所属俱乐部(默认为空)
    league:赛事(默认空)
    recommand:关联热门话题(默认0)
    orderBy:排序方式。【0:发布时间降序;1:发布时间升序;2:固顶降序;3:置顶降序;4:日点击降序;5:周点击降序;6:月点击降序;7:季点击降序;8:年点击降序;9:总点击降序】(默认0)
    memberId:关联版主。
    hot:是否推荐
    lala:0:啦啦团 1:球迷会 2:专题
-->
<#macro CfgList league='0' recommend='0' orderBy='0' lala="-1" hot="0" memberId="0" count="5" pageNo="0" hot="0"
    titLen='20' target='0' headMark='0' lineHeight='' bottomLine='0' ctgForm='0' ctgClass='' dateFormat='0' datePosition='1' memberId="0"
    picWidth='24.9' picHeight='110'
    rollDisplayHeight='28' rollLineHeight='28' rightPadding='20' rollCols='1' rollSpeed='1' isSleep='1' rollSleepTime='50' rollCount='1' rollSpan='1'
    flashWidth='296' flashHeight='200' textHeight='20'
    isPage='0' count='20' firstResult='0' pageNo=pageNo
    style='1' inner='0' isLoop='1' cssClass='' cssStyle='' showLinkStyle='1'
    sysTpl='1' sysContent='0' userContent='' sysPage='0' newday='0' userPage='' upSolution='' upWebRes='' pageClass='' pageStyle='' custom=[]>
    
    <@s.action name='CfgList' league=league namespace='/fcms/tag/article' executeResult='true'  memberId=memberId
        recommend=recommend orderBy=orderBy count=count lala=lala  hot=hot
        titLen=titLen target=target headMark=headMark lineHeight=lineHeight bottomLine=bottomLine ctgForm=ctgForm ctgClass=ctgClass dateFormat=dateFormat datePosition=datePosition
        picWidth=picWidth picHeight=picHeight
        rollDisplayHeight=rollDisplayHeight rollLineHeight=rollLineHeight rightPadding=rightPadding rollCols=rollCols rollSpeed=rollSpeed isSleep=isSleep rollSleepTime=rollSleepTime rollCount=rollCount rollSpan=rollSpan
        flashWidth=flashWidth flashHeight=flashHeight textHeight=textHeight
        isPage=isPage count=count firstResult=firstResult pageNo=pageNo
        style=style cssClass=cssClass cssStyle=cssStyle showLinkStyle=showLinkStyle
        sysTpl=sysTpl sysContent=sysContent userContent=userContent sysPage=sysPage newday=newday userPage=userPage pageClass=pageClass pageStyle=pageStyle customs=customs
        />
        <#if isLoop=='1'>
              <#list n_pagination.list as item>
                <#nested item,item_index,item_has_next/>
            </#list>
    <#else>
        <#nested n_pagination/>
    </#if>
</#macro>

上述代码中不难发现使用了宏,并且会向指定的namespace、action参数请求数据,在这里提醒一下必须还要加上 <#nested> (指令执行指令开始和结束标记之间的模板片断)

否则在页面上打印出来的不是你想要的数据,而是你的项目src根目录下的各种文件名称,这一点我暂时没弄明白。
