Embedded Jetty + Spring MVC main method - spring-mvc

Question

I'm using Embedded Jetty and Spring MVC and i'm starting my WebApplication through the main function.
i don't like the way it's looks, it's not very clean and i have the feeling i'm doing something wrong even though it's working just fine.
my problem is that i want to initialize ServerHolder,ServletContextHandler and Server objects outside the main method, but i cannot do it because DispatcherServlet requires and ApplicationContext.
Any ideas?
public static void main(String[] args) throws Exception {
AnnotationConfigWebApplicationContext applicationContext = new AnnotationConfigWebApplicationContext();
applicationContext.register(EPConfiguration.class);
ServletHolder servletHolder = new ServletHolder(new DispatcherServlet(applicationContext));
ServletContextHandler context = new ServletContextHandler();
context.setContextPath("/");
context.addServlet(servletHolder, "/*");
BasicConfigurator.configure();
Server server = new Server();
server.setHandler(context);
//HTTP
ServerConnector connector = new ServerConnector(server);
connector.setPort(9999);
server.setConnectors(new Connector[]{connector});
server.start();
server.join();
}

I'm not familier with Jetty, but you can setup and initialize DispatcherServlet in the following way:
Declare a java class which implements the abstract class AbstractAnnotationConfigDispatcherServletInitializer (it usually will be called WebAppInitializer).
Implement its abstract methods - getRootConfigClasses() (which return the classes which configure Application Context), getServletConfigClasses() (which returns the classes which configure the ServletContext) and getServletMappings() (which sets the DispatcherServletmapping).
I usually call the class that configures the ServletContext as WebConfig. You should annotate it with the #Configuration and #EnableWebMvc. In addition you should use it to define a ViewResolver bean:
```java
#Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/view"):
resolver.setSuffix(".jsp");
resolver.setExposeContextBeansAsAttributes(true);
return resolver;
}
```
