过滤器方案

@Configuration
public class CorsFilterConfig {
    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.setAllowCredentials(true);
        corsConfiguration.addAllowedOriginPattern("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.setMaxAge(10000L);
        source.registerCorsConfiguration("/**", corsConfiguration);
        return new CorsFilter(source);
    }

}

Spring拦截器方案

@Configuration
@RequiredArgsConstructor
public class WebMvcConfiguration implements WebMvcConfigurer {
  @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOriginPatterns("*")
                .allowedMethods("*")
                .allowCredentials(true)
                .allowedHeaders("*")
                .maxAge(3600);
    } 
}
