how to specify welcome-file-list in WebApplicationInitializer.onStartup()

Currently I have a web application where we are using web.xml to configure the application. The web.xml has welcome-file-list.

<web-app>  
   ....  

   <welcome-file-list>  
   <welcome-file>home.html</welcome-file>  
   </welcome-file-list>  
</web-app>  

We are planning to use spring framework and use java class for application configuration.

class MyApplication extends WebApplicationInitilizer{
    public void onStartUp(ServletCntext context){
        .....
    }
}

How do I specify welcome-file-list in this java class?
