inIn your project application.properties file set the naming strategy:
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.EJB3NamingStrategy Default value is org.springframework.boot.orm.jpa.SpringNamingStrategy
UPDATE:
If previous property does not solved your problem, you can use this one (For newer versions of Hibernate):
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
