Autowiring inside contextInitialized method of Context Listener

I am trying to autowiring my bean inside contextInitialized() method of my custom Context Listener class, but it is not working.

public class CustomContextListener extends ContextLoaderListener {
    @Autowired
    private MyBeanClass bean;

    @Override
    public void contextInitialized(javax.servlet.ServletContextEvent event) {
          super.contextInitialized(event);
          //call to my method.
          bean.mymethod();
}

But here it is not getting autowired, i am getting null object for MyBeanClass reference. How to autowire a class at the time of tomcat startup. Please provide me alternate places where i can execute some code using autowiring at the time of server startup (here tomcat).

I would suggest to use the WebApplicationContext method to find the bean and then invoke.

WebApplicationContext servletContext =  WebApplicationContextUtils.getWebApplicationContext(event.getServletContext());

bean = (MyBeanClass) servletContext.getBean("myBeanClass");
bean.yourMethod();

More systematic to use... :)
