Generating JPA entities with IntelliJ without a persistence.xml or orm.xml

Question

Is there a way to generate JPA entities with IntelliJ without a persistence.xml file? Or basically have IntelliJ recognize a persistance unit from Java Config? I have an existing (legacy) schema and the project is a rewrite, now using Java Config in Spring Boot. Per the Spring Boot docs, the persistence unit will be created by code:

@Bean
public LocalContainerEntityManagerFactoryBean customerEntityManagerFactory(
        EntityManagerFactoryBuilder builder) {
    return builder
            .dataSource(dataSource())
            .packages(com.abc.DomainThing.class)
            .persistenceUnit("abc")
            .build();
}

Answer 1

I solved this by having a persistence.xml in the project and not really used by code or checked in. It just makes the IDE happy and I can bind a datasource to it to get the DB schema help in JPA Entity classes.
