public abstract class AbstractAnnotationConfigDispatcherServletInitializer extends AbstractDispatcherServletInitializer
WebApplicationInitializer
to register a DispatcherServlet and use Java-based Spring configuration.
Implementations are required to implement:
getRootConfigClasses() -- for "root" application context (non-web
infrastructure) configuration.
getServletConfigClasses() -- for DispatcherServlet
application context (Spring MVC infrastructure) configuration.
If an application context hierarchy is not required, applications may
return all configuration via getRootConfigClasses() and return
null from getServletConfigClasses().

@Nullable protected org.springframework.web.context.WebApplicationContext createRootApplicationContext()
This implementation creates an AnnotationConfigWebApplicationContext,
providing it the annotated classes returned by getRootConfigClasses().
Returns null if getRootConfigClasses() returns null.

DispatcherServlet.
The returned context is delegated to Spring's
DispatcherServlet(WebApplicationContext). As such,
it typically contains controllers, view resolvers, locale resolvers, and other
web-related beans.
This implementation creates an AnnotationConfigWebApplicationContext,
providing it the annotated classes returned by getServletConfigClasses().

null if all configuration is specified through root config classes.
