hibernate column name issues

Try putting this in

application.properties

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

Here is a possible workaround: if you name it dateofbirth the column in the DB would be named like that, but the attribute name should be the same.

Hibernate takes the camel case format to create/read database columns.

I've had this problem before. I worked with a legacy columns where there was no space in the column names "employeename", "employeerole", "departmentlocation". I hate it because all my beans properties had to be without camel case.

Database columns separated by "_" will be used to properly camelCase as you have just seen.

FYI: The reason for the insertion of underscores is probably because you're using an ImprovedNamingStrategy. It's set on your Configuration object. See here for an example...

If you don't want the underscores you can just not set the naming strategy, or set it to the DefaultNamingStrategy you discovered earlier.

add below property in the case of spring boot.

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