java - What are the possible values of spring.datasource.initialization-mode?

Question

I am configuring a database in Spring JPA and I want to know what the possible values are of spring.datasource.initialization-mode. I found this page with common properties but it doesn't give all possible values. I'd expect there to be some documentation on all possible values of all properties you can set.

I am using the property in the props section in my applicationContext.xml as properties for the entityManagerFactory

<util:properties id="props">
    <prop key="hibernate.show_sql">true</prop>
    <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQL82Dialect</prop>
    <prop key="hibernate.hbm2ddl.auto">create</prop>
    <prop key="hibernate.ddl-auto">create</prop>
    <prop key="spring.jpa.show-sql">true</prop>
    <prop key="spring.jpa.generate.ddl">true</prop>
    <prop key="spring.jpa.hibernate.ddl-auto">create</prop>
    <prop key="spring.datasource.initialization-mode">always</prop>
    <prop key="spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation">true</prop>
</util:properties>

When all else fails, you remember "use the source, Luke!". The values are given in the Javadoc of the enum DataSourceInitializationMode. Values are always, embedded and never.
