Column Name Annotation Ignored in Spring Boot JPA

Problem:

Despite using column annotations in Spring Boot applications with data-jpa dependency, the generated SQL table column names differ from the annotations.

Cause:

This behavior is typically caused by the hibernate dialect used. In versions prior to Hibernate 5, Hibernate uses a default naming strategy that prefixes column names with an underscore. To override this strategy, you need to explicitly specify the naming strategy.

Solution:

For Hibernate 4:

Set the spring.jpa.hibernate.naming_strategy property to org.hibernate.cfg.EJB3NamingStrategy:

<code class="properties">spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy</code>

For Hibernate 5:

Add the following lines to your application.properties file:

<code class="properties">spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl</code>

By using these settings, Hibernate will adopt a naming strategy that respects the column annotations specified in your entities.
