spring boot return 403 forbidden when POST request with Keyclaok

I am using Keycloak to authenticate my spring boot application,

I have create a new realm (CommonServices) with a client (chatting-system)

I have this configuration 

keycloak:
  auth-server-url: http://localhost:8083/auth
  realm: CommonServices
  resource: chatting-system
  public-client: true
  principal-attribute: preferred_username
  use-resource-role-mappings: true
  security-constraints[0].authRoles[0]: user
  ssl-required: external

spring:
  data:
    mongodb:
      host: localhost
      port: 27017
      database: Chat
      username: saga
      password: password

  security:
    oauth2:
      resourceserver:
        jwt:
          jwk-set-uri: http://localhost:8083/auth/realms/CommonServices/protocol/openid-connect/certs
          issuer-uri: http://localhost:8083/auth/realms/CommonServices

and I have configured the security as such: 

@KeycloakConfiguration
class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
        auth.authenticationProvider(keycloakAuthenticationProvider);
    }

    @Bean
    @Override
    protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
        return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http.authorizeRequests()
                .antMatchers("/**")
                .hasRole("user")
                .anyRequest()
                .authenticated();
    }
}

@Configuration
public class KeycloakConfig {

    @Bean
    public KeycloakSpringBootConfigResolver keycloakConfigResolver() {
        return new KeycloakSpringBootConfigResolver();
    }
}

THE ISSUE

when I access my GET api everything goes fine but

if I access the POST rest API I get 403 forbidden

I guess that's a problem with CSRF protection that Spring Security enables by default. Try disabling it in your SecurityConfig to make sure that's the case.

@Override
protected void configure(HttpSecurity http) throws Exception {
    super.configure(http);
    http
            .csrf().disable() // <- THIS LINE
            .authorizeRequests()
            .antMatchers("/**")
            .hasRole("user")
            .anyRequest()
            .authenticated();
}

If that's the reason, I recommend to set up proper CSRF protection, as disabling it is time saving in terms of development, but overall is not a good idea in terms of deploying to production.
