[Spring Boot]Could not obtain connection to query metadata

오류 save 부분에 insert가 안됨

 

구글링하다가 yml파일에

spring:
  h2:
    console:
      enabled: true
  jpa:
    generate-ddl: true
    hibernate:
      ddl-auto: create-drop

    database: H2
    show-sql: true
    open-in-view: false
    properties:
      hibernate:
        dialect: org.hibernate.dialect.PostgreSQLDialect
        query.in_clause_parameter_padding: true
        hbm2ddl:
          auto: create-drop

hbm2ddl.auto부분 추가했더니 잘됨
