Java-buildpack: JBP는 Spring Boot 2.0을 지원합니까?

아직 테스트하지 않았지만 실행 방식( java -jar )이 변경되지 않았으므로 변경되지 않을 것이라고 믿을 이유가 없습니다.

실제로 현재 M3에 문제가 있습니다. 그러나 이것은 MongoDB를 사용할 때만 발생합니다. Cloud Foundry는 MongoDB 연결을 재구성하려고 시도하고 NoSuchMethodError 됩니다.

내가 볼 수 있는 한 이것은 spring-data-mongo 종속성의 주요 변경 사항 때문입니다.

설정은 다음을 위한 스타터가 포함된 기본 Spring Boot 2.0.0.M3 앱입니다.

• 액추에이터
• 데이터 몽고
• 편물
• 등.

예, 이것은 자동 재구성 문제입니다. 우리는 Spring Data로의 주요 버전 업그레이드를 위해 준비되지 않았을 수 있는 Spring Cloud Connectors의 버전에 의존합니다. @scottfrederick 은 이것을 알고 있고 내가 해야 할 일은 Spring Cloud Connectors의 새 버전을 사용하기 시작하는 것뿐입니까?

Java 테스트 응용 프로그램을 Boot 2.0 으로 업데이트했습니다. 그 작업에 따르면 문제가 있는 것으로 보이는 유일한 것은 Spring Data Mongo의 자동 재구성이 깨진 것 같다(API 변경). 나는 이 문제를 이에 대한 지표로 남겨두고 수정 사항이 마련되면 닫을 것입니다.

언제 사용할 수 있습니까? 또한 현재 적용 가능한 해결 방법이 있습니까?

우리는 제공에 매우 가깝지만 @scottfrederick 이 Spring Cloud Connectors의 릴리스를 수행하기를 여전히 기다리고 있습니다. 자동 재구성을 단순화하고 Spring Cloud Connectors 2.x를 사용하도록 업그레이드하기 위해 상당한 작업 을 는 구성된 모든 유형이 Boot 1.x와 Boot 2.x에서 모두 호환되는지 확인하기 위해 제출했습니다 . 이것은 포함되었지만 아직 테스트 중입니다. 일단 출시되면 우리는 그것을 소비 하고 자동 재구성의 새 버전을 야생으로 가져올 것입니다.

MongoDB 자동 재구성을 제외한 모든 것이 오늘 예상대로 작동하므로 실제로 해결할 필요가 없습니다. MongoDB의 자동 재구성을 시도하는 경우 서비스를 사용하도록 애플리케이션을 명시적으로 구성하는 것 외에는 해결 방법이 없습니다(어쨌든 수행해야 합니다. 자동 재구성은 프로덕션 시스템에 좋은 선택이 아닙니다).
