How to Fix the

Spring Security CORS Filter

Problem

When Spring Security is added to an existing project, a "401 No 'Access-Control-Allow-Origin' header is present on the requested resource" error is encountered. This occurs because an Access-Control-Allow-Origin header is not added to the response.

Solution

To resolve this issue, since Spring Security 4.1, the proper way to enable CORS support is as follows:

In WebConfig:

@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedMethods("HEAD", "GET", "PUT", "POST", "DELETE", "PATCH");
    }
}

Copy after login

In SecurityConfig:

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
//        http.csrf().disable();
        http.cors();
    }

    @Bean
    public CorsConfigurationSource corsConfigurationSource() {
        final CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(ImmutableList.of("*"));
        configuration.setAllowedMethods(ImmutableList.of("HEAD",
                "GET", "POST", "PUT", "DELETE", "PATCH"));
        configuration.setAllowCredentials(true);
        configuration.setAllowedHeaders(ImmutableList.of("Authorization", "Cache-Control", "Content-Type"));
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

Copy after login

Incorrect Solutions

Avoid using the following incorrect solutions:

http.authorizeRequests().antMatchers(HttpMethod.OPTIONS, "/**").permitAll();
web.ignoring().antMatchers(HttpMethod.OPTIONS);
