나는 작업 intellij,내가 설정된 환경 변수에 Maven 구성(오른쪽 상단에,추가 구성,러너,환경 변수)
그것은 그것과 같은 변수를 읽고 이름으로 대신 문자열 변수 도시
응용 프로그램 속성:
server.port=8081
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://${MYSQL_HOST}?zeroDateTimeBehavior=convertToNull
spring.datasource.username=${SERVICE_USER}
spring.datasource.password=${SERVICE_PASSWORD}
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.hibernate.globally_quoted_identifiers=true
#spring.jpa.show-sql: true
환경변수(에 maven 구성):
SERVICE_PASSWORD=;MYSQL_HOST=localhost:3306/orderup;SERVICE_USER=root
메시지:
No such host is known (${MYSQL_HOST})
