Why is spring.jpa.hibernate.naming.implicit-strategy and physical-strategy being ignored and FK columns have underscores? - spring

Question

I have two entity classes:
#Entity
#Data
public class Holiday {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private LocalDate date;
#ManyToOne
private Calendar calendar;
}
#Entity
#Data
public class Calendar {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
}
When I run an integration test, I'm getting the following error:
org.springframework.dao.InvalidDataAccessResourceUsageException: could
not extract ResultSet; SQL [n/a]; nested exception is
org.hibernate.exception.SQLGrammarException: could not extract
ResultSet at
... 78 more Caused by:
com.microsoft.sqlserver.jdbc.SQLServerException: Invalid column name
'calendar_id'. at
The database has calendarId as the FK. I know that underscore is the default but my application.yml file has:
spring:
jpa:
hibernate:
naming:
implicit-strategy: org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
This should change have hibernate indicate the column as calendarId. Why does this not work? I'm using Spring Boot 2.7.5.

You can explicitly name the column:
#Column(name = "Calendarid")
