<p>ConfiguratorFactory 继承关系图</p>
<p>其中，OverrideConfiguratorFactory 对应的扩展名为 override，创建的 Configurator 实现是 OverrideConfigurator；AbsentConfiguratorFactory 对应的扩展名是 absent，创建的 Configurator 实现类是 AbsentConfigurator。</p>

<p>其中，AbstractConfigurator 中维护了一个 configuratorUrl 字段，记录了完整的配置 URL。<strong>AbstractConfigurator 是一个模板类，其核心实现是 configure() 方法</strong>，具体实现如下：</p>
<pre><code>public URL configure(URL url) {
