java - Restrict which requests a ServletDispatcher processes -

can control requests specific dispatcherservlet instances allowed issue? have defined 2 dispatchers, 1 service requests /public/public* , private/private*.

here dispatchers

@springbootapplication public class application extends springbootservletinitializer {    public static void main(string[] args) {       applicationcontext ctx = springapplication.run(application.class, args);    }    @override    protected springapplicationbuilder configure(          springapplicationbuilder application) {       return application.sources(application.class);    }    @bean    public dispatcherservlet dispatcherservletpublic() {       return new dispatcherservlet();    }    @bean    public servletregistrationbean dispatcherservletpublicregistration() {       servletregistrationbean registration =             new servletregistrationbean(dispatcherservletpublic(), "/public/public*");       registration.setname(dispatcherservletautoconfiguration.default_dispatcher_servlet_registration_bean_name);       return registration;    }    @bean    public dispatcherservlet dispatcherservletprivate() {       return new dispatcherservlet();    }    @bean    public servletregistrationbean dispatcherservletprivateregistration() {       servletregistrationbean registration =             new servletregistrationbean(dispatcherservletpublic(), "/private/private*");       registration.setname("private");       return registration;    } } 

the request mappings.

@restcontroller public class rmbonecontroller {    @requestmapping("/public-data")    public string publicdata() {        return "here data: 42.";    }    @requestmapping("/private-data")    public string privatedata() {       return "here private data: 43.";    } } 

this doesn't work. getting whitelabel error page these 2 urls. not context root war /.

http://localhost:8080/private/private-data http://localhost:8080/public/public-data 

and few items confused about

• i trying way because it's close servlet mappings - define servlet class respond givens urls.

  <servlet-mapping>    <servlet-name>publicservlet</servlet-name>    <url-pattern>/public/*</url-pattern> </servlet-mapping> ... <servlet>    <servlet-name>publicservlet</servlet-name>    <servlet-class>foo.bar.publicservlet</servlet-class>    <load-on-startup>2</load-on-startup> </servlet> 

• i thinking might way implement public , private areas - later put login filters on private dispatcher. see on page spring boot features - security assumption being way start authentication wrong. (i haven't had time yet go further it).
• soooo... possible restrict requests dispatcher can process.
• and why might done way?
