使用多个数据源时忽略 Hibernate 隐式命名策略

Question

According to the following tutorial, I created two configruation files for two database sources: Baeldung-JPA-Multiple-Databases

It works fine, but it seems that the implicit naming strategy is ignored. That means that an Entity CustomerContact is not mapped to a table customer_contact .

I tried to add the following two properties, but nothing changes:

public LocalContainerEntityManagerFactoryBean primaryEntityManager() {
    ...
    properties.put("hibernate.naming.implicit-strategy", "org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy");
    properties.put("hibernate.naming.physical-strategy", "org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy");
    em.setJpaPropertyMap(properties);
    ...
}

One solution would be to use the name attribute of the persistence annotations, like @Entity(name = "customer_contact") , but I would like to avoid that and use the implicit mapping instead.

The answer can be found here: Can't set JPA naming strategy after configuring multiple data sources (Spring 1.4.1 / Hibernate 5.x)

The needed properties are:

props.put("hibernate.physical_naming_strategy", SpringPhysicalNamingStrategy.class.getName());
props.put("hibernate.implicit_naming_strategy", SpringImplicitNamingStrategy.class.getName());
