使用IntelliJ生成JPA实体而不使用persistence.xml或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

我通过在项目中使用persistence.xml解决了这个问题，并没有真正被代码使用或签入。它只是让IDE开心，我可以将数据源绑定到它以获得JPA Entity类中的DB模式帮助。
