JEECMS自帶的只有[@cms_advertising]標簽，并且官方沒有給文檔，用法:

[@cms_advertising?id='3']?
????????????<img?src="${(tag_bean.attr.image_url)!?html}"?width="${(tag_bean.attr.image_width)!?html}"?height="${(tag_bean.attr.image_height)!?html}"?/>?
?[/@cms_advertising]

這個是根據廣告ID的來調用單獨的一條廣告，首頁幻燈片一般都有多張，不能滿足需求。

其實jeecms也有另一個js調用已經實現了的，但是不能生成到html中，用戶體驗不好。（com.jeecms.cms.action.front.AdvertisingAct類，<script src="/ad.jspx" ?……）

?

回到正題，自己增加一個標簽，名字叫做：cms_advertising_space

?

步驟一：

jeecms-context.xml中增加一個bean：

1 2	<!-- 新增按照廣告牌取所有廣告標簽 --> <bean?id="cms_advertising_space" class="com.jeecms.cms.action.directive.CmsAdvertisingSpaceDirective"/>

步驟二：

jeecms.properties添加cms_advertising_space標簽

1	directive.cms_advertising_space=cms_advertising_space

　　

步驟三：

新增一個類：CmsAdvertisingSpaceDirective

package com.jeecms.cms.action.directive;import static com.jeecms.common.web.freemarker.DirectiveUtils.OUT_BEAN; import static freemarker.template.ObjectWrapper.DEFAULT_WRAPPER;import java.io.IOException; import java.util.HashMap; import java.util.List; import java.util.Map;import org.springframework.beans.factory.annotation.Autowired; import static com.jeecms.common.web.freemarker.DirectiveUtils.OUT_LIST; import com.jeecms.cms.entity.assist.CmsAdvertising; import com.jeecms.cms.entity.assist.CmsAdvertisingSpace; import com.jeecms.cms.manager.assist.CmsAdvertisingMng; import com.jeecms.cms.manager.assist.CmsAdvertisingSpaceMng; import com.jeecms.common.web.freemarker.DirectiveUtils;import freemarker.core.Environment; import freemarker.template.TemplateDirectiveBody; import freemarker.template.TemplateDirectiveModel; import freemarker.template.TemplateException; import freemarker.template.TemplateModel;/*** 廣告對象標簽*/ public class CmsAdvertisingSpaceDirective implements TemplateDirectiveModel {/*** 輸入參數，廣告ID。*/public static final String PARAM_ID = "id";@SuppressWarnings("unchecked")public void execute(Environment env, Map params, TemplateModel[] loopVars,TemplateDirectiveBody body) throws TemplateException, IOException {Integer id = DirectiveUtils.getInt(PARAM_ID, params);List<CmsAdvertising> ads = null;CmsAdvertisingSpace adspace;if (id != null) {//ad = cmsAdvertisingMng.findById(id);ads= cmsAdvertisingMng.getList(id, true);}Map<String, TemplateModel> paramWrap = new HashMap<String, TemplateModel>(params);if (ads!=null){paramWrap.put(OUT_LIST, DEFAULT_WRAPPER.wrap(ads));}Map<String, TemplateModel> origMap = DirectiveUtils.addParamsToVariable(env, paramWrap);body.render(env.getOut());DirectiveUtils.removeParamsFromVariable(env, paramWrap, origMap);}@Autowiredprivate CmsAdvertisingMng cmsAdvertisingMng;@Autowiredprivate CmsAdvertisingSpaceMng cmsAdvertisingSpaceMng; }

?

標簽寫法：

1 2 3 4 5 6

[@cms_advertising_space id='7'] [#list tag_list as c] ? <img?src="${(c.attr.image_url)!?html}" width="${(c.attr.image_width)!?html}" height="${(c.attr.image_height)!?html}" /> [/#list]??? ?[/@cms_advertising_space]

　　生成代碼：

1 2 3

<img?src="http://127.0.0.1:8080/r/cms/kingyon_zh/uploads/7-140611092P2415.jpg" width="" height="" /> ? <img?src="http://127.0.0.1:8080/r/cms/kingyon_zh/uploads/3-140611092P2415.jpg" width="" height="" />
