<p> <span>每个MBean Server都有一个<em>类加载程序存储</em>库，其中包含MBean服务器中注册的所有MBean，它们都是<a href="../../../java/lang/ClassLoader.html" title="java.lang中的类"><code>ClassLoader</code></a>的子类。</span> <span><a href="../../../javax/management/MBeanServer.html" title="javax.management中的接口"><code>MBeanServer</code></a>接口中没有显式加载程序参数的<code>createMBean</code>和<code>instantiate</code>方法的形式使用了类加载程序库。</span> <span><code>MLet</code>类当它在自己的一组URL中找不到一个类时也使用它。</span> </p>
<p> <span>如果MBean实现了接口<a href="../../../javax/management/loading/PrivateClassLoader.html" title="javax.management.loading中的接口"><code>PrivateClassLoader</code></a> ，那么它不会添加到类加载程序库。</span> <span><a href="../../../javax/management/loading/PrivateMLet.html" title="javax.management.loading中的类"><code>PrivateMLet</code></a>类是<code>MLet</code>的子类，实现<code>PrivateClassLoader</code> 。</span> </p>
