写个过滤器配置类

@Bean
public CorsWebFilter corsWebFilter() {
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    CorsConfiguration corsConfiguration = new CorsConfiguration();
    //配置跨域
    corsConfiguration.addAllowedHeader("*");
    corsConfiguration.addAllowedMethod("*");
    corsConfiguration.addAllowedOriginPattern("*");
    corsConfiguration.setAllowCredentials(true);

    source.registerCorsConfiguration("/**", corsConfiguration);
    return new CorsWebFilter(source);
}
