CakePHP中的操作会进行意外重定向

Question

我在CakePHP 2.7中创建了一个网站。我有一个名为AdsController.php的控制器并创建了一个名为buscar（）的操作;

在AdsController.php的buscar（）中：

    // método para buscar
    public function buscar(/* $uf = null,
      $city = null,
      $newspaper = null, */
    $year1 = null, $month1 = null, $day1 = null, $year2 = null, $month2 = null, $day2 = null) { // tenho que validar os nulos
        $options = array(
            'conditions' => array(
                "Ad.created >=" => $year1 . '-' . $month1 . '-' . $day1 . ' 00:00:00',
                "Ad.created <=" => $year2 . '-' . $month2 . '-' . $day2 . ' 23:59:59'
            )
        );

        $this->set(
                array(
                    'ad' => $this->Ad->find('first', $options),
                    '_serialize' => array('ad')
                )
        );
    }

app / Config / routes.php

<?php

Router::connect('/', array('controller' => 'pages', 'action' => 'display', 'home'));

Router::connect('/pages/*', array('controller' => 'pages', 'action' => 'display'));

//Criando RESTful
//Router::mapResources('ads');
// Ativando rotas RESTful
Router::connect('/ads/:year1/:month1/:day1/:year2/:month2/:day2',  array('controller' => 'ads', 'action' => 'buscar'), array(

    'year1' => '[12][0-9]{3}',
    'month1' => '0[1-9]|1[012]',
    'day1' => '0[1-9]|[12][0-9]|3[01]',
    'year2' => '[12][0-9]{3}',
    'month2' => '0[1-9]|1[012]',
    'day2' => '0[1-9]|[12][0-9]|3[01]',
        )
);


/**
 * Load all plugin routes. See the CakePlugin documentation on
 * how to customize the loading of plugin routes.
 */
CakePlugin::routes();

/**
 * Load the CakePHP default routes. Only remove this if you do not want to use
 * the built-in default routes.
 */
require CAKE . 'Config' . DS . 'routes.php';


// Ativando extensão .json
Router::parseExtensions('json');

索引为http://localhost/classificado。

当我调用操作时，例如localhost/classificado/ads/buscar/2015/09/01/2015/10/10，或者当我调用localhost/classificado/ads/2015/09/01/2015/10/10时，请指向routes.php，它转到localhost/classificado/classificado/ads/add并抛出错误：

  

无法找到ClassificadoController。

但我没有重定向到此。请帮帮我。
