해결했습니다ㅜBoot 3으로 해서인지 gateway server 프로젝트를 만들면서 gateway 라이브러리를 추가하니까'<a target="_blank" rel="noopener noreferrer nofollow" href="http://org.springframework.cloud">org.springframework.cloud</a>:spring-cloud-starter-gateway'가 아니라'<a target="_blank" rel="noopener noreferrer nofollow" href="http://org.springframework.cloud">org.springframework.cloud</a>:spring-cloud-starter-gateway-mvc'가 추가되었더라구요.그래서 '<a target="_blank" rel="noopener noreferrer nofollow" href="http://org.springframework.cloud">org.springframework.cloud</a>:spring-cloud-starter-gateway' 로 변경하고&nbsp;eureka client 서버들 XXXApplication 클래스에 '@EnableDiscoveryClient' 어노테이션을 달고게이트웨이 서버 실행 후에 약간의 시간이 지나면 정상적으로 요청을 받을 수 있었습니다.감사합니다 ㅎㅎ 이어서 강의 들으러 가보겠습니다 메리크리스마스여

직접 어플리케이션 서버에 요청을 보내면 동작하는데, gateway 서버로 보내면 404가 뜹니다

instance-id 에 넣은 변수명?에 값이 매칭되지 않아서어플리케이션서버(rms)로 온 요청 url에서 오류가 나는 것 같습니다. 제가 이해한 게 맞을까요?&nbsp;2023-12-21T22:54:20.338+09:00 INFO 28432 --- [rms] [tbeatExecutor-0]
