 * <ul>
 * <li><code>replaceSensitive</code>:替换敏感词, 默认为<code>true</code>
 * <li><code>id</code>:用户id,结果返回<code>object</code>
 * {@link com.publiccms.entities.sys.SysUser}

 * 多个用户id,逗号或空格间隔,当id为空时生效,结果返回<code>map</code>(id,<code>object</code>)
 * <li><code>absoluteURL</code>:cover处理为绝对路径 默认为<code> true</code>
