java - Spring REST security - Secure different URLs differently

Question

I have working REST API under Spring 4 using Basic authentication. These REST services are under /api/v1/** URL. However, I want to add another set of REST endpoints under different url /api/v2/**, but protected with token-based authentication.

Is it possible to do this with one servlet ? How to configure Spring Security to use different forms of authentication for different URLs ?

Thank you.

Here's a code sample in Java config that uses UserDetailsService and has different security configurations for different URL endpoints:

@Configuration
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    UserDetailsService userDetailsService;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService);
    }

    @Configuration
    @Order(1)
    public static class ApiWebSecurityConfig extends WebSecurityConfigurerAdapter{

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
                    .antMatcher("/api/v1/**")
                    .httpBasic()
                        .realmName("API")
                        .and()
                    .csrf().disable()
                    .authorizeRequests()
                    .antMatchers("/api/v1/**").authenticated();
        }
    }

    @Configuration
    @Order(2)
    public static class ApiTokenSecurityConfig extends WebSecurityConfigurerAdapter{

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
                    .antMatcher("/api/v2/**")
                    /* other config options go here... */
        }

    }
}
