이 문제와 관련하여 여기에서 몇 가지 질문을 읽고 강력히 믿습니다.저지 웹 서비스 만 반환 404

package Rest;

내가 함께 저지 2.XX을 사용 Tomcat v9.0. 항상 404 찾을 수 없음을 보여

http://localhost:8080/RestTest/rest/hello/Tuan

http://localhost:8080/RestTest/rest/hello/

http://localhost:8080/RestTest/Rest/hello/Tuan

내가 좋아하는 일부 URL을 시도했다.

왜 그런가? @Libin으로

Tomcat 관리자에서 컨텍스트 루트 "RestTest"가 올바른지 확인하는 것이 좋습니다. –

@AlexR 안녕하세요, 이클립스를 사용하여이 프로젝트를 빌드하고 그 사실을 알지 못합니다.하지만 웹 프로젝트 설정/컨텍스트 루트에서 이클립스를 확인한 경우 실제로 RestTest입니다. –

내가 잘못하지 않았다면 @Path ("/ {param}")는 @Path ("{param}") 여야합니다. – Libin
