📑 FilterConfig 클래스 생성 및 설정

package com.example.web2_apigateway_gatewayservice.config;

import org.springframework.cloud.gateway.route.RouteLocator;
import org.springframework.cloud.gateway.route.builder.RouteLocatorBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class FilterConfig {

    @Bean
    public RouteLocator gatewayRoutes(RouteLocatorBuilder builder) {
        return builder.routes()
                .route(r -> r.path("/first-service/**")
                        .filters(f -> f.addRequestHeader("first-request", "first-request-header")
                                .addResponseHeader("first-response11", "first-response-header1"))
                        .uri("http://localhost:8081/"))

                        .uri("http://localhost:8082/"))
                .build();
    }
}
