Spring security antMatcher does not work

Question

EDIT:

I further drilled down the problem and turns out issue persists even with single configuration. If I use single configuration and keep

http.antMatcher("/api/test/**")

urls don't get secured. Removing the antMatcher and antMatchers immediately secures the url. i.e if I use:

http.httpBasic()
    .and()
    .authorizeRequests()
    .anyRequest()
    .authenticated();

then only spring security is securing url. Why isn't antMatcher functioning?

(Updated the title to include actual issue.)

Original Post:

I have referred following stackoverflow questions:

1. Spring REST security - Secure different URLs differently

2. Using multiple WebSecurityConfigurerAdapter with different AuthenticationProviders (basic auth for API and LDAP for web app)

and spring security doc:

https://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#multiple-httpsecurity

But I am not able to configure multiple http security elements. When I follow the official spring doc, it works in my case only becuase of the fact that the second http security element is a catch-all, but as soon as I add a specific url, all the urls can be accessed without any authentication.

Here's my code:

@EnableWebSecurity
@Configuration
public class SecurityConfig {

    @Bean                                                             
    public UserDetailsService userDetailsService() throws Exception {
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withUsername("user").password("userPass").roles("USER").build());
        manager.createUser(User.withUsername("admin").password("adminPass").roles("ADMIN").build());
        return manager;
    }


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

        @Override       
        public void configure(AuthenticationManagerBuilder auth) 
          throws Exception {            
            auth.inMemoryAuthentication().withUser("user").password("user").roles("USER");
            auth.inMemoryAuthentication().withUser("admin").password("admin").roles("ADMIN");
        }

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

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

        @Override       
        public void configure(AuthenticationManagerBuilder auth) 
          throws Exception {

            auth.inMemoryAuthentication().withUser("user1").password("user").roles("USER");
            auth.inMemoryAuthentication().withUser("admin1").password("admin").roles("ADMIN");
        }

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
                .antMatcher("/api/test/**")
                .authorizeRequests()
                .antMatchers("/api/test/**").authenticated()
                    .and()
                .formLogin();
        }
    }
}

Now any url can be accessed. If I remove antMatcher from second configuration, all the urls become secured.

Answer 1

The pattern must not contain the context path, see AntPathRequestMatcher:

Matcher which compares a pre-defined ant-style pattern against the URL ( servletPath + pathInfo) of an HttpServletRequest.

and HttpServletRequest.html#getServletPath:

Returns the part of this request's URL that calls the servlet. This path starts with a "/" character and includes either the servlet name or a path to the servlet, but does not include any extra path information or a query string. Same as the value of the CGI variable SCRIPT_NAME.

and HttpServletRequest.html#getContextPath:

Returns the portion of the request URI that indicates the context of the request. The context path always comes first in a request URI. The path starts with a "/" character but does not end with a "/" character. For servlets in the default (root) context, this method returns "". The container does not decode this string.

Your modified and simplified code:

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .antMatcher("/test/**")
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .formLogin();
    }
