本文介绍了Zend Framework中Zend_Controller_Plugin_Abstract类的基本用法及如何通过继承实现自定义插件。该类提供了请求和响应对象的管理，并定义了多个回调方法以支持插件功能。

Zend_Controller_Plugin_Abstract 是一个专门用于插件编写的抽象类，动手术之前肯定要分析的类的源码，Zend framework在某种程度上说慢，一部分也是由于includet的文件实在过于复杂累赘，启动mvc那么此文件已经载入系统，为您和您的家人提供方便，呵呵~

我们所做的工作就是将其重载
class MyPlugin extends Zend_Controller_Plugin_Abstract
{
 public function routeStartup(Zend_Controller_Request_Abstract $request)
 {
 $this->getResponse()->appendBody("routeStartup() called/n");
 }

public function routeShutdown(Zend_Controller_Request_Abstract $request)
 {
 $this->getResponse()->appendBody("routeShutdown() called/n");
 }

public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request)
 {
 $this->getResponse()->appendBody("dispatchLoopStartup() called/n");
 }

public function preDispatch(Zend_Controller_Request_Abstract $request)
 {
 $this->getResponse()->appendBody("preDispatch() called/n");
 }

public function postDispatch(Zend_Controller_Request_Abstract $request)
 {
 $this->getResponse()->appendBody("postDispatch() called/n");
 }

public function dispatchLoopShutdown()
 {
 $this->getResponse()->appendBody("dispatchLoopShutdown() called/n");
 }
}

建议其插件的使用是其后期补救的一种手段而已
