java - Access-Control-Allow-Origin header is missing - Spring boot cors

Question

When i make a GET or POST request to my rest api i get Vary:origin header but i actually need Access-Control-Allow-Origin header

i have these:

Security config class:

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

                .authorizeRequests()
                .antMatchers("/auth/**").permitAll()
                .anyRequest().authenticated()
                .and()
                .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
    
  .addFilterBefore(authenticationTokenFilterBean(),UsernamePasswordAuthenticationFilter.class);
    }
}

Cors configuration class

@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedMethods("GET", "POST")
                .allowedOrigins("*")
                .allowedHeaders("Content_Type", "Authorization");
    }
}
