Como eu configuro o CORS para esse projeto

opa tudo bem?

aqui ta um exemplo basico que vc pode usar.

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class CorsConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
            .allowedOrigins("http://localhost:8080") // Substitua com a origem permitida
            .allowedMethods("OPTIONS", "GET", "POST", "PUT", "DELETE")
            .allowedHeaders("*");
    }
}

Muito obrigado pela ajuda Alisson mas eu ainda continuo com o problema, será que teria mais algum ajuste.

Será que eu preciso fazer algum ajuste aqui :

package modelo.spring.api.infra.security;

import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.http.HttpMethod; import org.springframework.security.authentication.AuthenticationManager; import org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration; import org.springframework.security.config.annotation.method.configuration.EnableMethodSecurity; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.http.SessionCreationPolicy; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; import org.springframework.security.crypto.password.PasswordEncoder; import org.springframework.security.web.SecurityFilterChain; import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

@Configuration @EnableWebSecurity @EnableMethodSecurity(securedEnabled = true) public class SecurityConfigurations {

@Autowired
private SecurityFilter securityFilter;

@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
    return http.csrf(csrf -> csrf.disable())
            .sessionManagement(sm -> sm.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
            .authorizeHttpRequests(req -> {
                req.requestMatchers(HttpMethod.POST, "/login").permitAll();
                req.requestMatchers("/v3/api-docs/**", "/swagger-ui.html", "/swagger-ui/**").permitAll();
                req.anyRequest().authenticated();
            })
            .addFilterBefore(securityFilter, UsernamePasswordAuthenticationFilter.class)
            .build();
}

@Bean
public AuthenticationManager authenticationManager(AuthenticationConfiguration configuration) throws Exception {	
    return configuration.getAuthenticationManager();	
}

@Bean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

}

opa tudo bem? nessa linha vc alterou para sua url origim?

 .allowedOrigins("http://localhost:8080") // Substitua com a origem permitida

aqui ta localhost:8080, no seu caso seria localhost:4200
