前端获取不了rest请求自定义headers的问题

@Configuration
public class CORSConfiguration implements WebMvcConfigurer {
    @Bean
    public CorsFilter corsFilter() {
        final UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource();
        final CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.setAllowCredentials(true); /*是否允许请求带有验证信息*/
        corsConfiguration.addAllowedOrigin("*");/*允许访问的客户端域名*/
        corsConfiguration.addAllowedHeader("*");/*允许服务端访问的客户端请求头*/
        corsConfiguration.addAllowedMethod("*"); /*允许访问的方法名,GET POST等*/
        corsConfiguration.addExposedHeader("token");/*暴露哪些头部信息 不能用*因为跨域访问默认不能获取全部头部信息*/
        corsConfiguration.addExposedHeader("Authorization");
        urlBasedCorsConfigurationSource.registerCorsConfiguration("/**", corsConfiguration);
        return new CorsFilter(urlBasedCorsConfigurationSource);
    }
}
