Spring Boot + JPA : Column name annotation ignored

For Hibernate 5, I solved this issue by adding the following lines in my application.properties file:

spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

By default Spring uses org.springframework.boot.orm.jpa.SpringNamingStrategy to generate table names. This is a very thin extension of org.hibernate.cfg.ImprovedNamingStrategy. The tableName method in that class is passed a source String value but it is unaware if it comes from a @Column.name attribute or if it has been implicitly generated from the field name.

The ImprovedNamingStrategy will convert CamelCase to SNAKE_CASE where as the EJB3NamingStrategy just uses the table name unchanged.

If you don't want to change the naming strategy you could always just specify your column name in lowercase:

@Column(name="testname")

It seems that

@Column(name="..")

is completely ignored unless there is

spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy

specified, so to me this is a bug.

I spent a few hours trying to figure out why @Column(name="..") was ignored.
