[linux] 올바른 방법으로 Spring Boot 애플리케이션을 종료하는 방법은 무엇입니까?

나는 끝점을 노출하지 않고 ( 백그라운드에서 nohup을 사용하고 nohup을 통해 만든 파일을 제외하고 ) 쉘 스크립트로 중지하고 ( KILL PID를 사용하여 정상적으로 3 분 후에도 앱이 계속 실행중인 경우 강제 종료) 중지 합니다. 실행 가능한 jar를 만들고 PID 파일 작성기를 사용하여 PID 파일을 작성하고 Jar 및 Pid를 응용 프로그램 이름과 동일한 이름의 폴더에 저장하고 셸 스크립트도 시작 및 중지와 같은 이름을 가지고 있습니다. 이 중지 스크립트를 호출하고 jenkins 파이프 라인을 통해 스크립트를 시작합니다. 지금까지 문제가 없습니다. 8 개 응용 프로그램에 완벽하게 작동합니다 (매우 일반적인 스크립트이며 모든 응용 프로그램에 적용하기 쉽습니다).

메인 클래스

@SpringBootApplication
public class MyApplication {

    public static final void main(String[] args) {
        SpringApplicationBuilder app = new SpringApplicationBuilder(MyApplication.class);
        app.build().addListeners(new ApplicationPidFileWriter());
        app.run();
    }
}

YML 파일

spring.pid.fail-on-write-error: true
spring.pid.file: /server-path-with-folder-as-app-name-for-ID/appName/appName.pid

다음은 시작 스크립트 (start-appname.sh)입니다.
