Hibernate naming strategy changing table names

Question

I\'m a little bit confused by hibernates (version 5.1) naming strategy - namely it changes my table name and I\'d like to avoid that. Also - spring.jpa.hibernate.namin

Answer 1

The problem lies in spring-boot-1.4 - it seems like they have changed the properties (or whatever) I've now found this answer ImprovedNamingStrategy no longer working in Hibernate 5, but it still didn't resolve correctly. So I have changed the code a little to not use the underscore method and to extend the newly introduced class SpringPhysicalNamingStrategy:

package com.foo;

import org.hibernate.boot.model.naming.Identifier;
import org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl;
import org.hibernate.engine.jdbc.env.spi.JdbcEnvironment;

import java.io.Serializable;
import java.util.Locale;


public class RealNamingStrategyImpl extends org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy implements Serializable {

    public static final PhysicalNamingStrategyImpl INSTANCE = new PhysicalNamingStrategyImpl();

    @Override
    public Identifier toPhysicalTableName(Identifier name, JdbcEnvironment context) {
        return new Identifier(name.getText(), name.isQuoted());
    }

    @Override
    public Identifier toPhysicalColumnName(Identifier name, JdbcEnvironment context) {
        return new Identifier(name.getText(), name.isQuoted());
    }

}

And in application.properties I've changed the deprecated line to

spring.jpa.properties.hibernate.physical_naming_strategy=.RealNamingStrategyImpl

Now it uses exactly the table and column names as I have them in my entity files.
