Spring Boot Security ignores cors configuration

Question

I added Spring Security (5.0.0.RELEASE) with JWT Authentication to Spring Boot (1.5.7.RELEASE), but the CORS seems to not work. I added the CORS configuration as described here. I also tried adding @CrossOrigin to the controllers, but it doesn't seem to change anything.

When calling POST and GET requests from the front-end (Angular JS 5) there doesn't seem to be any CORS problem, but when calling DELETE I get CORS error.

Here's the security configuration:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
public class WebSecurity extends WebSecurityConfigurerAdapter {
    private UserDetailsService userDetailsService;
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    public WebSecurity(UserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.userDetailsService = userDetailsService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

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

        http
                .cors()
                .and()
                .csrf()
                .disable()
                .authorizeRequests()
                .antMatchers(HttpMethod.POST, SIGN_UP_URL).permitAll()
                .antMatchers(HttpMethod.GET, ACTIVATE_URL).permitAll()
                .antMatchers(AUTH_WHITELIST).permitAll()
                .anyRequest().authenticated()
                .and()
                .addFilter(new JWTAuthenticationFilter(authenticationManager()))
                .addFilter(new JWTAuthorizationFilter(authenticationManager()))
                // this disables session creation on Spring Security
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration configuration = new CorsConfiguration().applyPermitDefaultValues();
        configuration.setAllowedOrigins(Collections.singletonList("*"));
        configuration.addAllowedMethod(HttpMethod.TRACE);

        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

And here are the headers from postman when sending OPTIONS request:

Allow →DELETE,GET,HEAD,POST
Cache-Control →no-cache, no-store, max-age=0, must-revalidate
Content-Length →0
Date →Fri, 12 Jan 2018 13:22:08 GMT
Expires →0
Pragma →no-cache
X-Content-Type-Options →nosniff
X-Frame-Options →DENY
X-XSS-Protection →1; mode=block

The allow-access-control-origin header is missing, as well as the HTTP TRACE I added to see if the configuration is working.

And the spring security debug logs:

Answer 1

When using a breakpoint as dur sugested it turned out allowMethods was always null

Adding the following line to corsConfigurationSource fixed it:

configuration.setAllowedMethods(Arrays.asList("GET", "POST", "DELETE", "OPTIONS"));
