/**
 *
 * dictionaryExclude 数据字典排除规则查询指令
 * <p>
 * 参数列表
 * <ul>
 * <li><code>dictionaryId</code>:数据字典id
 * <li><code>excludeDictionaryId</code>
 * 排除的字典,结果返回<code>object</code>{@link com.publiccms.entities.cms.CmsDictionaryExclude}
 * <li><code>excludeDictionaryIds</code>
 * 多个排除的字典,逗号或空格间隔,当excludeDictionaryId为空时生效,结果返回<code>map</code>(id,<code>object</code>)
 * </ul>
 * <p>
 * 使用示例
 * <p>
 * &lt;@cms.dictionaryExclude dictionaryId='data'
 * excludeDictionaryId='data1'&gt;${object.id.excludeDictionaryId}&lt;/@cms.dictionaryExclude&gt;
 * <p>
 * &lt;@cms.dictionaryExclude dictionaryId='data'
 * excludeDictionaryIds='data1,data2'&gt;&lt;#list map as
 * k,v&gt;${k}:${v.id.excludeDictionaryId}&lt;#sep&gt;,&lt;/#list&gt;&lt;/@cms.dictionaryExclude&gt;
