How to get table names in snake case with Quarkus and Panache

Question

I have Java entities with a composite camel case name, e.g., EmployeeProject.

I need to map those entities on tables with snake case names, e.g., employee_project, instead of the default used by Quarkus/Panache, e.g., employeeproject.

I know I can set a custom table name with @Entity(name = "employee_project") but I was wondering if there is some sort of application property which do the same work for me.

Answer 1

Hibernate copied the CamelCaseToUnderscoresNamingStrategy from Spring.

Just use it like this, without defining it again.

quarkus.hibernate-orm.physical-naming-strategy=org.hibernate.boot.model.naming.CamelCaseToUnderscoresNamingStrategy
