<p> <span>提供MBean服务器引用。</span> <span>没有这个类的实例。</span> </p>
|
||
<p> <span>由于JMX 1.2这个类可以替换默认的MBeanServer实现。</span> <span>这是使用<a href="../../javax/management/MBeanServerBuilder.html" title="javax.management中的类"><code>MBeanServerBuilder</code></a>类完成的。</span> <span>要实例化的初始MBeanServerBuilder的类可以通过<b>javax.management.builder.initial</b>系统属性指定。</span> <span>指定的类必须是一个公共子<a href="../../javax/management/MBeanServerBuilder.html" title="javax.management中的类"><code>MBeanServerBuilder</code></a> ，而且必须有一个公共的空构造。</span> </p>
|
||
<p> <span>默认情况下，如果指定该属性没有值，实例<a href="../../javax/management/MBeanServerBuilder.html" title="javax.management中的类"><code>javax.management.MBeanServerBuilder</code></a>创建。</span> <span>否则，MBeanServerFactory尝试使用<a href="../../java/lang/Thread.html#getContextClassLoader--"><code>Thread.currentThread().getContextClassLoader()</code></a>加载指定的类，或者如果该值为空， <a href="../../java/lang/Class.html#forName-java.lang.String-">则为<code>Class.forName()</code></a> 。</span> <span>然后它使用<a href="../../java/lang/Class.html#newInstance--"><code>Class.newInstance()</code></a>创建该类的初始实例。</span> <span>如果任何检查的异常在此过程中提出的（如<a href="../../java/lang/ClassNotFoundException.html" title="java.lang中的类"><code>ClassNotFoundException</code></a> ， <a href="../../java/lang/InstantiationException.html" title="java.lang中的类"><code>InstantiationException</code></a> ）的使用MBeanServerFactory将从一个RuntimeException内传播此异常。</span> </p>
|
||
<p> <span>每次需要创建新的MBeanServer时，都会<b>查询javax.management.builder.initial</b>系统属性，并加载该属性指向的类。</span> <span>如果该类与当前MBeanServerBuilder的类不同，则创建一个新的MBeanServerBuilder。</span> <span>否则，MBeanServerFactory可能会创建一个新的MBeanServerBuilder或重用当前的。</span> </p>
|
||
<p> <span>如果属性指向的类无法加载，或者不对应于MBeanServerBuilder的有效子类，则会传播异常，并且不会创建MBeanServer，直到将<b>javax.management.builder.initial</b>系统属性重置为有效值。</span> </p>
|
||
<p> <span>MBeanServerBuilder可以包装默认MBeanServerBuilder实现返回的MBeanServers，以便添加额外的安全层。</span> </p>
