Change default controller in Magento

I have created a modules:

app/code/local/MyStore/Welcome

And in this module, I have a controller like:

MyStore_We开发者_如何学Pythonlcome_IndexController

From my current knowledge, I see at the beginning Magento load Mage_Cms_IndexController controller as the default controller.

Now I want to load MyStore_Welcome_IndexController controller as default.

How can I do that?

Update:

I've found a way to do using admin feature: From the menu you chose: System/Configuration/Web: You continue to choose: "Default Page" => "Default Web URL" to field the module:

You need to make sure that your controller extends Mage_Cms_IndexController and then override that default controller via the controller overloading method. In this method you will create a plugin as per usual, but you need to do the following:

• add the declaration require_once() at the top with the relative path to the controller you're overloading. E.g. :

  require_once 'Mage/Checkout/controllers/OnepageController.php';
  class MyClass_OverloadedCheckout_Checkout_OnepageController extends Mage_Checkout_OnepageController
  

• Create any class methods or properties that you may want to add in addition to the default.

• in your config.xml add the following lines outside of the <global> node:

    <frontend>
        <routers>
            <myclass_overloadedcheckout>
                <use>standard</use>
                <args>
                    <module>Myclass_OverloadedCheckout</module>
                    <frontName>OverloadedCheckout</frontName>
                </args>
            </myclass_overloadedcheckout>
        </routers>
    </frontend>
  

Something to remember - if you rewrite any default methods you need to return parent::{methodname} either before or after your injected functionality to ensure that the default behaviors continue to operate.

You should think again if you really want to do it because it is a huge change, but you could simply override the Mage_Cms_IndexController. How you can override a controller, you can find e.g. here.

Anyway, I would try to solve the problem another way. Maybe you can use the Event/Observer Pattern?
