Spring, nginx proxy HATEOAS

nginx, Spring Hateoas, proxy_pass

Proxy server 뒤에 backend Server 구성시 url forward

구성

frontend, proxy : nginx

backend : spring boot

문제

Spring HATEOAS 적용시 link url 부분은 proxy 부분이 제거된 상태로 return

요청 url : http://localhost/api/erp/inv/onhand/87/3203?direction=ASC&page=0&size=5&sort=seq,asc

"_links":{"first":{"href":"http://localhost/inv/onhand/87/3203?direction=ASC&page=0&size=5&sort=seq,asc"},"self":{"href":"http://localhost/inv/onhand/87/3203?direction=ASC&page=0&size=5&sort=seq,asc"},"next":{"href":"http://localhost/inv/onhand/87/3203?direction=ASC&page=1&size=5&sort=seq,asc"},"last":{"href":"http://localhost/inv/onhand/87/3203?direction=ASC&page=1&size=5&sort=seq,asc"}

요청 url - api/erp 부분

응답 links - api/erp 부분 누락

정상 결과

"_links":{"first":{"href":"http://localhost/api/erp/inv/onhand/87/3203?direction=ASC&page=0&size=5&sort=seq,asc"},"self":{"href":"http://localhost/api/erp/inv/onhand/87/3203?direction=ASC&page=0&size=5&sort=seq,asc"},"next":{"href":"http://localhost/api/erp/inv/onhand/87/3203?direction=ASC&page=1&size=5&sort=seq,asc"},"last":{"href":"http://localhost/api/erp/inv/onhand/87/3203?direction=ASC&page=1&size=5&sort=seq,asc"}
