spring boot jar를 실행파일로 만드는 법

spring excutable jar 생성

https://www.baeldung.com/spring-boot-app-as-a-service

exe 파일처럼 jar 파일이 바로 실행할 수 있는 파일이 된다

sudo ln -s /path/to/your-app.jar /etc/init.d/your-app

sudo service your-app start

daemon 용 쉘스크립트가 내장되어서 배포된다

jsvc 를 이용하는 것보다 편리한 방법이다

jsvc 를 이용하려면 commons-daemon 을 상속받아 구현해야 하는데...

pom.xml 에서 플러그인을 수정

<plugin>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-maven-plugin</artifactId>

    <configuration>

        <executable>true</executable>

    </configuration>

</plugin>

nohup 으로 서비스를 돌리는 것과 daemon 을 이용하는 것의 차이점
