Spring boot CORS 처리

Config 추가.

@Configuration
@RequiredArgsConstructor
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    private final CorsProperties corsProperties;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .cors()
    }

    /*
    * Cors 설정
    * */
    @Bean
    public UrlBasedCorsConfigurationSource corsConfigurationSource() {
        UrlBasedCorsConfigurationSource corsConfigSource = new UrlBasedCorsConfigurationSource();

        CorsConfiguration corsConfig = new CorsConfiguration();
        corsConfig.setAllowedHeaders(Arrays.asList(corsProperties.getAllowedHeaders().split(",")));
        corsConfig.setAllowedMethods(Arrays.asList(corsProperties.getAllowedMethods().split(",")));
        corsConfig.setAllowedOrigins(Arrays.asList(corsProperties.getAllowedOrigins().split(",")));
        corsConfig.setAllowCredentials(true);
        corsConfig.setMaxAge(corsConfig.getMaxAge());

        corsConfigSource.registerCorsConfiguration("/**", corsConfig);
        return corsConfigSource;
    }
}

 

apllicaiton.properties 또는 yml

 

# cors
cors.allowed-origins=http://localhost:3000
cors.allowed-methods=GET,POST,PUT,DELETE,OPTIONS
cors.allowed-headers=authorization,content-type,x-auth-token
cors.max-age=3600

 

Enable Config.

@SpringBootApplication
@EnableConfigurationProperties({
    CorsProperties.class
})
public class TestApplication {

	public static void main(String[] args) {
		SpringApplication.run(TestApplication.class, args);
	}

}

 

이렇게 하면 rest api 서버에서 cors 처리를 해 줄 수 있다.
