EJB3NamingStrategy vs ImprovedNamingStrategy Foreign Key Naming

Question

My naming strategy in hibernate was the default one : EJB3NamingStrategy. So the field and table names was in camelcase. I switched it to ImprovedNamingStrategy to have snakecase.

But my foreign keys doesn't include the primary key name of the referenced entity in the name.

Example:

table1: id name

With EJB3NamingStrategy the table2 fields will be:

table2: id table1_id

but with ImprovedNamingStrategy the table2 fields will be: table2: id table1

Is there a way to have _id with the ImprovedNamingStrategy. I don't understand why hibernate behave differently because the logicalCollectionColumnName method in both strategy are identical.

Answer 1

Extend the improvedNamingStrategy and customize, maybe the initial implementation of the ImprovedNamingStrategy got this wrong and then they couldn't fix it as it would break backward compatability.

Answer 2

This issue is resolved in spring boot 1.2.7.RELEASE. Reference of this thread is also specified in the documentation of the jpa hibernate package. Class signature as follows:

package org.springframework.boot.orm.jpa.hibernate;

public class SpringNamingStrategy extends ImprovedNamingStrategy {}
