java - Need help converting from web.xml spring boot -

i trying convert web.xml based web app spring boot having trouble configuring httprequesthandlerservlet. have following in web.xml:

<servlet>   <servlet-name>webservices</servlet-name>   <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet>  <servlet>   <servlet-name>updateservlet</servlet-name>   <servlet-class>org.springframework.web.context.support.httprequesthandlerservlet</servlet-class> </servlet>  <servlet-mapping>   <servlet-name>updateservlet</servlet-name>   <url-pattern>/update</url-pattern> </servlet-mapping>  <servlet-mapping>   <servlet-name>webservices</servlet-name>   <url-pattern>/ws/*</url-pattern> </servlet-mapping> 

the dispatcherservlet not problem:

@springbootapplication public class webapplication extends springbootservletinitializer {   public static void main(string[] args)   {     springapplication.run(poolwebapplication.class);   }    @bean   public dispatcherservlet dispatcherservlet()   {     return new dispatcherservlet();   }    @bean   public servletregistrationbean servletregistrationbean()   {     return new servletregistrationbean(dispatcherservlet(), "/ws/*");   } } 

but can't figure out how configure updateservlet.

how 1 configure httprequesthandlerservlet based servlet in spring boot application?

additional info:

i tried suggested answer doesn't work me.

one thing didn't mention updateservlet named "updateservlet": componenet("updateservlet") public class updateservlet implements httprequesthandler

that name conflicts bean name in answer. after changing (to update), get:

no bean named 'httprequesthandlerservlet' defined 

after changing name of updateservlet httprequesthandlerservlet, get

org.springframework.beans.factory.beannotofrequiredtypeexception: bean named 'httprequesthandlerservlet' must of type [org.springframework.web.httprequesthandler], of type [org.springframework.web.context.support.httprequesthandlerservlet] 

for dispatcherservlet there easier way add line application.properties , remove servlet bean application class.

server.servlet-path=/ws/* 

next add definition of httprequesthandlerservlet configuration instead of dispatcherservlet.

@springbootapplication public class webapplication extends springbootservletinitializer {   public static void main(string[] args)   {     springapplication.run(poolwebapplication.class);   }    @bean   public httprequesthandlerservlet updateservlet()   {     return new httprequesthandlerservlet();   }    @bean   public servletregistrationbean updateservletregistrationbean()   {     return new servletregistrationbean(updateservlet(), "/update");   } } 

upd:

note, using updateservlet() method absolutely legal here, , can used springbean instance (see comments below).
