IntelliJ에서 Spring Boot와 Jrebel 연동시 수정사항이 제대로 반영 안되는 현상 해결

현상

자바 코드는 특성상 업데이트를 하면 컴파일 및 배포를 다시 해줘야 하는데 이 과정을 줄이고 생산성을 높히기 위하여 Spring과 JRebel을 연동해서 사용하고 있었다.

IntelliJ로 Spring Boot 프로젝트를 생성하고, 이전처럼 JRebel과 연동을 해주었는데 프로젝트를 올리니 에러 없이 JRebel 메세지가 나왔다.

그런데 hot swap (수정한 코드가 바로 반영되는 것)이 적용되지 않았다.

이전에 Spring을 사용할때에도 비슷한 현상이 있었는데 이는 IntelliJ -> Setting -> Compiler -> Build Automatically 옵션을 체크해서 해결할 수 있었다. 그런데 이번에는 정상적으로 체크되어 있음에도 핫스왑이 정상적으로 동작하지 않았다.

해결

팀원분의 서포트로 문제를 해결할 수 있었다.
registry 메뉴에서 compiler.automake.allow.when.app.running 를 체크해주면 핫스왑이 정상적으로 동작한다.

참고

Spring boot devtools - Static content reloading does not work in IntelliJ
