Commons Proxy 是 Apache 的一个之项目，封装了 Java 对象代理的一些常用方法。    <ul>     <li><b>Deferred Initialization</b> - the proxy acts as a "stand-in" for the actual implementation allowing it to be instantiated only when absolutely necessary.</li>     <li><b>Security</b> - the proxy object can verify that the user actually has the permission to execute the method (a la EJB).</li>     <li><b>Logging</b> - the proxy can log evey method invocation, providing valuable debugging information.</li>     <li><b>Performance Monitoring</b> - the proxy can log each method invocation to a performance monitor allowing system administrators to see what parts of the system are potentially bogged down.</li>    </ul>    <p><strong>项目主页：</strong><a href="http://www.open-open.com/lib/view/home/1326940830858" target="_blank">http://www.open-open.com/lib/view/home/1326940830858</a></p>
