GORM으로 MongoDB 데이터에 액세스 할 때 샘플을 시도 할 때

Question

Accessing MongoDB Data with GORM에 대한 자습서를 수행했지만 샘플 Groovy 코드에 문제가 있습니다. 샘플 Groovy 코드를 app.groovy라는 파일에 복사했습니다. 스프링 부트 cli에서 코드를 실행하면 코드가 제대로 작동합니다. 내가

spring jar my-app.jar *.groovy 

를 실행 한 후

java -jar my-app.jar 

을 실행하여 항아리에 코드를 컴파일하면 나는

누구든지 내가이 문제를 해결하거나 내가 무엇을 얼마나 어떤 생각을 가지고 (자), IllegalStateException를 얻을 잘못하고있는거야?

Answer 1

아마도 버그 일 수 있습니다 : https://github.com/spring-projects/spring-boot/issues/686. 어쩌면 클래스 로더 문제 일지 모르겠습니다.하지만 해결 될 때 여기에서 살펴볼 것입니다. 그 동안 Gradle 또는 Maven 빌드를 사용하여 실행 가능한 JAR을 생성 할 수 있어야합니다.

업데이트 : Spring Boot 및/또는 GORM에서이 문제를 해결할 수 있지만 그 동안에는 app.groovy (예 : package app)의 패키지를 선언하면 문제가 해결됩니다.
