java.lang.IllegalArgumentException: Unrecognized legacy `hibernate.hbm2ddl.auto` value : `false`

강좌에서 말씀하신대로 ddl-auto를 꺼놓고 소스코드를 적었더니 아래와 같은 에러가 발생했습니다. 어떻게 해결하면 좋을까요...

org.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is java.lang.IllegalArgumentException: Unrecognized legacy `hibernate.hbm2ddl.auto` value : `false`
