How to tweak NamingStrategy for Spring Data JDBC
how do i tweak the Spring Data JDBC NamingStrategy to behave like Hibernate´s PhysicalNamingStrategy?
I have the following entity:
/**
* Campus domain model class.
* Handles information about campus.
*
* @author thomas.lang@th-deg.de
*/
@Data
@AllArgsConstructor(access = AccessLevel.PRIVATE, onConstructor = @__(@PersistenceConstructor))
public class Campus {
private final @Id
@Wither
long campusId;
@NotNull
@Size(min = 3)
private String campusName;
/**
* Creates a new campus.
*
* @param campusName
*/
public Campus(@NonNull String campusName) {
this.campusId = 0;
Assert.hasLength(campusName, "A valid value has to be provided for Campus!");
this.campusName = campusName;
}
}
When i want JDBC to persist a test record, it generates this sql:[INSERT INTO campus (campus_name) VALUES (?)]
My existing Database has a column named campusname
I have read on the docu here https://docs.spring.io/spring-data/jdbc/docs/1.0.2.RELEASE/reference/html/#jdbc.entity-persistence.naming-strategy that i can tweak the naming strategy, but i don´t know how :)
Thank you for your help!
Kind regards!

Create a bean of type NamingStrategy in your application context and implement its methods to your liking.
The method that you need to override is getColumnName(RelationalPersistentProperty)
