1.项目目录：
创建项目gateway作为父类
2.代码实现：
父类依赖

@SpringBootApplication@EnableDiscoveryClientpublic class GatewayClientApplication { public static void main(String[] args) { SpringApplication.run(GatewayClientApplication.class, args); }}创建module项目gateway-service
添加依赖

@Configurationpublic class CorsConfig { @Bean public CorsWebFilter corsFilter() { CorsConfiguration config = new CorsConfiguration(); config.addAllowedMethod("*"); config.addAllowedOrigin("*"); config.addAllowedHeader("*"); UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser()); source.registerCorsConfiguration("/**", config); return new CorsWebFilter(source); }}3.实现效果：
启动nacos后，再启动gateway-client, gateway-service项目，打开浏览器http://localhost:8001/client/index
返回信息：gateway-client端口：8002
