Hibernate OGM provider for Spring configuration

Hello,
I created a Java application that can use SQL Server or Neo4j as a database without touching the application layer, I just modify the provider and the connection information, like follows:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
 
    <persistence-unit name="jpa-tutorial" transaction-type="RESOURCE_LOCAL">
        <!--For SQL Server-->
        <!--provider>org.hibernate.ejb.HibernatePersistence</provider>
        <!--class>com.mycompany.hibernate.Atom</class-->
        
        <!--For Neo4j-->
        <provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>
        
        
        <properties>
            <!--For Neo4j-->
            <property name="hibernate.ogm.datastore.provider" value="neo4j_embedded" />
            <property name="hibernate.ogm.neo4j.database_path" value="D:/Stage/Neo4j/NEO4J_HOME_4/data/graph.db" />
            
            <!--For SQL Server-->
            <!--property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/atom" />
            <property name="javax.persistence.jdbc.user" value="root" />
            <property name="javax.persistence.jdbc.password" value="" />
 
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.hbm2ddl.auto" value="updatr" /-->
         </properties>
 
    </persistence-unit>
</persistence>

I have now to make the same thing but with a Spring application. I've started learning Spring but found a completely new logic. For example, there is a different provider of JPA:

Code:

Does that mean that there's no way to do the same as the first application? I mean there's no Hibernate OGM provider that I can just put in the place of HibernateJpaVendorAdapter in order to make the application running on Neo4j rather than SQL Server?

Thanks in advance.

Hi,

I don't think you need the JPA vendor adaptor, e.g. see this SO post: https://stackoverflow.com/questions/9684197/why-did-i-need-to-define-a-hibernate-jpa-vendor-adapter-in-my-spring-application. You still can drive your persistence configuration through persistence.xml, also when working with Spring.

Hth,
