Questions:
My question is quite simple.
Is it possible to add a DAO from a referenced library?
Fx. if you have multiple micro-services running sharing a some DAOs.
<persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<non-jta-data-source>DefaultDS</non-jta-data-source>
<class>someproject.models.awesomeDAO</class>
<class>referencedLibrary.models.sharedDAO</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
</properties>
</persistence-unit>
How to&Answers:
I assume by DAOs you actually mean Entities. You can add any entity class explictly with the <class> tag in persistence.xml as long as they are in the classpath.
You can even reference a jar file to be searched for annotated classes so you don’t need to declare them explicitly with the tag <jar-file>
