Spring Security with Java Configuration: How to Handle a BadCredentialsException from a Custom Provider

I need to authenticate some rest services using the token identifier in the url (or perhaps in the request header), but this is not important so far. I am trying to use java configuration to install this using this post as a guide . My problem is that I do not know how to handle the "BadCredentialsException", which occurs when authentication fails with the provider. Here is my security configuration:

public static class SecurityConfigForRS extends
        WebSecurityConfigurerAdapter {

    @Autowired
    TokenAuthenticationProvider tokenAuthenticationProvider;

    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.authenticationProvider(tokenAuthenticationProvider);
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean()
            throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);

        http.regexMatcher("^/rest.*")
                .addFilterBefore(
                        new TokenAuthenticationFilter(
                                authenticationManagerBean()),
                        AbstractPreAuthenticatedProcessingFilter.class)
                .and().csrf().disable();

    }
}

For now, I am skipping other implementations - if that helps, I will post them later.

GenericFilterBean, . AbstractAuthenticationProcessingFilter . :

public class TokenAuthenticationProcessingFilter extends
    AbstractAuthenticationProcessingFilter {

public TokenAuthenticationProcessingFilter(
        RequestMatcher requiresAuthenticationRequestMatcher) {
    super(requiresAuthenticationRequestMatcher);
}

@Override
public Authentication attemptAuthentication(HttpServletRequest request,
        HttpServletResponse response) throws AuthenticationException,
        IOException, ServletException {
    Authentication auth = new TokenAuthentication("-1");
    try {
        Map<String, String[]> params = request.getParameterMap();
        if (!params.isEmpty() && params.containsKey("auth_token")) {
            String token = params.get("auth_token")[0];
            if (token != null) {
                auth = new TokenAuthentication(token);
            }
        }
        return this.getAuthenticationManager().authenticate(auth);
    } catch (AuthenticationException ae) {
        unsuccessfulAuthentication(request, response, ae);
    }
    return auth;
}}

http:

    public static class SecurityConfigForRS extends
        WebSecurityConfigurerAdapter {

    @Autowired
    TokenAuthenticationProvider tokenAuthenticationProvider;

    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.authenticationProvider(tokenAuthenticationProvider);
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean()
            throws Exception {
        return super.authenticationManagerBean();
    }

    @Bean
    protected AbstractAuthenticationProcessingFilter getTokenAuthFilter()
            throws Exception {
        TokenAuthenticationProcessingFilter tapf = new TokenAuthenticationProcessingFilter(
                new RegexRequestMatcher("^/rest.*", null));
        tapf.setAuthenticationManager(authenticationManagerBean());
        return tapf;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);

        http.regexMatcher("^/rest.*")
                .addFilterAfter(getTokenAuthFilter(),
                        BasicAuthenticationFilter.class).csrf().disable();

    }
}

! BasicAuthenticationFilter, . , , !
