I am using 2 Weblogic data sources; In my XML configurations I have 2 persistence units, 2 entityManagerFactories, and 2 transactionManagers. The files are as follows:
persistence.xml:
<persistence-unit name="modelPersistence" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
</persistence-unit>
<persistence-unit name="orderPersistence" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
</persistence-unit>
config.xml:

ModelRepository:
@Repository ("ModelRepo")
@PersistenceContext(unitName = "modelPersistence")
public interface ModelRepository extends JpaRepository<Model, String> {}
orderRepository:

Any suggestions on the correct annotation for handling multiple transaction managers? Am I missing something else? Other stack-overflow examples use DAOs which I have not found helpful as I am using repositories, model, and controller java files. I am also not using hibernate, which a lot of examples reference as well. Your insight is appreciated.
I am receiving the following error:

You can use:
@Transactional("transactionManagerName")
See org.springframework.transaction.annotation.Transactional (@Transactional) annotation javadoc:
/**
* A qualifier value for the specified transaction.
* <p>May be used to determine the target transaction manager,
* matching the qualifier value (or the bean name) of a specific
* {@link org.springframework.transaction.PlatformTransactionManager}
* bean definition.
*/
String value() default "";
