How to integrate LiquiBase + Spring + Hibernate without using hibernate.xml configuration file

Question

I already read a lot of posts regarding integration between LiquiBase, Spring and Hibernate, but none of them apply to my situation witch is:

I'm starting a new project that uses Spring and Hibernate, so I was looking into a way to manage the database changes during the project lifetime. First I started using hbm2ddl but then realized that people say that this isn't a very good idea in production environments, so I came to the conclusion that LiquiBase was the way to go (so I think).

The problem is that I'm not using a hibernate.xml config file (and all the examples I found using LiquiBase use a hibernate.xml), since I'm using java annotations in my POJO/DB classes and my hibernate configuration is made like this

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() throws ClassNotFoundException
{
    LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();

    entityManagerFactoryBean.setDataSource(dataSource());
    entityManagerFactoryBean.setPackagesToScan(environment.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));
    entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistence.class);

    Properties jpaProterties = new Properties();
    jpaProterties.put(PROPERTY_NAME_HIBERNATE_DIALECT, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
    jpaProterties.put(PROPERTY_NAME_HIBERNATE_FORMAT_SQL, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_FORMAT_SQL));
    jpaProterties.put(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY));
    jpaProterties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
    jpaProterties.put(PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO));

    entityManagerFactoryBean.setJpaProperties(jpaProterties);

    return entityManagerFactoryBean;
}

I also found posts from 2 years ago saying that this option would only be available in version 2.0 (the current one), and I was wondering if this is already implemented. If so, how do I use it in a ANT script?

I need to create the original database DDL and the following database change logs and import them into the production DB.

EDIT : I'm using:

Liquibase 2.0.5

Liquibase Hibernate 2.0.0

Hibernate 4.1.4

Spring 3.1.1

Spring Data JPA 1.1.1

Did you look at http://www.liquibase.org/documentation/spring.html?

It mentions dataSource and no hibernate.xml.

For initial generation you can use command line mode and generateChangeLog.

See http://www.liquibase.org/documentation/command_line.html.

Here is a minimal hibernate.xfg.xml you're going to need:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
                "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
                "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory name="entityManagerFactoryBean">
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3307/test</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">123456</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
    </session-factory>
</hibernate-configuration>
