Access to XMLHttpRequest ''http://192.168.3.106:8080/sac/oauth/token' from origin 'http://localhost:3001' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

[vitor-ferreira-sousa]

good morning, I have an API raised in Payara Server, when I try to log in on the front of the error in cors but testing on Postmam the token request works normally because Postmam does not check the Cors, the error I have returned on the login screen is: "Access to XMLHttpRequest at 'http://192.168.3.106:8080/sac/oauth/token' from origin 'http://localhost:3001' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

The normal thing is to login correctly in the fronto which is controlled by Cors / Oauth2

CorsConfig:

import java.util.Collections;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@configuration
public class CorsConfig {

@Bean
public FilterRegistrationBean<CorsFilter> corsFilterRegistrationBean() {
	CorsConfiguration config = new CorsConfiguration();
	config.setAllowCredentials(true);
	config.setAllowedOriginPatterns(Collections.singletonList("*"));
	config.setAllowedMethods(Collections.singletonList("*"));
	config.setAllowedHeaders(Collections.singletonList("*"));

	UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
	source.registerCorsConfiguration("/**", config);

	FilterRegistrationBean<CorsFilter> bean = new FilterRegistrationBean<>();
	bean.setFilter(new CorsFilter(source));
	bean.setOrder(Ordered.HIGHEST_PRECEDENCE);

	return bean;
}

}
