Mix HttpBasic and FormLogin in Spring Security with Spring-boot-starter - spring

Question

I use spring-boot-starter 0.5.0.M6 with spring security to build my application which contains:
"/admin/"**: should be accessible to anyone have role ADMIN, form-based login
"/api/"**: should be accessible to anyone have role API, http basic login
My first attempt was:
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/resources/**").permitAll()
.antMatchers("/admin/**").hasRole("ADMIN")
.and()
.formLogin()
.defaultSuccessUrl("/admin/home")
.loginPage("/login")
.permitAll()
.and()
.logout()
.logoutRequestMatcher(new AntPathRequestMatcher("/logout", "GET"))
.permitAll();
http
.authorizeRequests()
.antMatchers("/api/**").hasRole("API")
.and()
.httpBasic();
}
With this approach:
all the "/admin/" and "/api/" can authentication use both basic & form-based login. This is not a critical issue.
when any security issue occurred, eg: authentication failed, or authorization failed, the login form is shown. This is a critical issue, I want if /api/** get authentication failed or authorization failed, it show the basic authentication popup with 401/403 status code.
Then I try with the solution from https://github.com/spring-projects/spring-security-javaconfig/blob/master/samples-web.md#sample-multi-http-web-configuration, but I only able to secure either /api/** or /admin/** but not both, depends on which one I annotated with #Order.
Please give me a hand.
Thanks much

For your api part, use the following. Note the first ant matcher that limits the scope of what is filtered by this security configuration. That was the part I did not understand at first from your reference.
#Configuration
#Order(1)
public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable();
// the ant matcher is what limits the scope of this configuration.
http.antMatcher("/api/**").authorizeRequests()
.antMatchers("/api/**").authenticated()
.and().httpBasic().realmName("Sourcing API");
}
}
