Could not verify the provided CSRF token because your session was not found in spring security

Question

I am using spring security along with java config

@Override
protected void configure(HttpSecurity http) throws Exception { 
    http
    .authorizeRequests()
    .antMatchers("/api/*").hasRole("ADMIN")
    .and()
    .addFilterAfter(new CsrfTokenResponseHeaderBindingFilter(), CsrfFilter.class)
    .exceptionHandling()
    .authenticationEntryPoint(restAuthenticationEntryPoint)
    .and()
    .formLogin()
    .successHandler(authenticationSuccessHandler)
    .failureHandler(new SimpleUrlAuthenticationFailureHandler());

I am using PostMan for testing my REST services. I get 'csrf token' successfully and I am able to login by using X-CSRF-TOKEN in request header. But after login when i hit post request(I am including same token in request header that i used for login post request) I get the following error message:

HTTP Status 403 - Could not verify the provided CSRF token because your session was not found.

Can any one guide me what I am doing wrong.

According to spring.io:

When should you use CSRF protection? Our recommendation is to use CSRF protection for any request that could be processed by a browser by normal users. If you are only creating a service that is used by non-browser clients, you will likely want to disable CSRF protection.

So to disable it:

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

Note: CSRF protection is enabled by default with Java Configuration
