You can add below code in Spring boot main class to redirect '/' request to '/login' page.

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.web.reactive.function.server.RouterFunction;
import org.springframework.web.reactive.function.server.ServerResponse;

import static org.springframework.web.reactive.function.server.RequestPredicates.GET;
import static org.springframework.web.reactive.function.server.RouterFunctions.route;   

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
    
    @Bean
    RouterFunction routerFunction() {
        return  route(GET("/"), req ->
                ServerResponse.temporaryRedirect(URI.create("/login"))
                        .build());
    }
}
