<p>在最新的 <code>Furion</code> 的 <code>1.1.6+</code> 版本中，新增了 <code>IEntityChangedListener</code> 实体数据监听接口，可以监听 <code>EFCore</code> 任何实体表 <code>增删改</code> 操作。</p>

<ul>
<li>类似数据库 <code>触发器</code> 功能，可实现 <code>增删改</code> 监听</li>
<li>可以实现特殊操作，比如刷新缓存，记录日志等</li>
</ul>

<p>在 <code>Furion</code> 框架中，默认不启用实体数据监听器，如想启用，只需要在 <code>数据库上下文</code> 构造函数中启用即可：</p>
