how to configure 'dispatcherServlet' load on startup by spring boot?

Question

I use spring-boot-starter-parent as parent and add spring-boot-starter-web as denpendency.

By add the @SpringBootApplication annotation, it works.

But DispatcherServlet need initialization

     Initializing servlet 'dispatcherServlet'
     FrameworkServlet 'dispatcherServlet': initialization started
     Using MultipartResolver [org.springframework.web.multipart.support.StandardServletMultipartResolver@745f40ac]
     Unable to locate LocaleResolver with name 'localeResolver': using default [org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver@219fc57d]
     Unable to locate ThemeResolver with name 'themeResolver': using default [org.springframework.web.servlet.theme.FixedThemeResolver@7b4bd6bd]
     Unable to locate RequestToViewNameTranslator with name 'viewNameTranslator': using default [org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator@71ccfa36]
     Unable to locate FlashMapManager with name 'flashMapManager': using default [org.springframework.web.servlet.support.SessionFlashMapManager@43f3e6a9]
     Published WebApplicationContext of servlet 'dispatcherServlet' as ServletContext attribute with name [org.springframework.web.servlet.FrameworkServlet.CONTEXT.dispatcherServlet]
     FrameworkServlet 'dispatcherServlet': initialization completed in 37 ms

I hope I can set it's loadonstartup by 1, and don't want to use this annoying BeanNameUrlHandlerMapping, it rejected everything and I'm not going to use it.

o.s.w.s.h.BeanNameUrlHandlerMapping      : Rejected bean name 'contextAttributes': no URL paths identified

I read the java-doc about BeanNameUrlHandlerMapping:

This is the default implementation used by the org.springframework.web.servlet.DispatcherServlet, along with org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping (on Java 5 and higher). Alternatively, SimpleUrlHandlerMapping allows for customizing a handler mapping declaratively.

That's all, I just want to change these two thing:

1. setLoadonStartup
2. don't use BeanNameUrlHandlerMapping

Beside that, other thing spring boot configure for me is very great, and I want to keep it.

Thank you for any help you can provide.

New reply to old post. Seems this is easier to do with more recent versions of Spring Boot. Just adding the property spring.mvc.servlet.load-on-startup=1 works for me.
