英文:
Hibernate Implicit Naming Strategy is ignored when using multiple datasources
问题
根据以下教程，我为两个数据库源创建了两个配置文件：Baeldung-JPA-Multiple-Databases
虽然它可以正常运行，但似乎隐式命名策略被忽略了。这意味着实体 CustomerContact 没有映射到表 customer_contact。
我尝试添加了以下两个属性，但没有任何变化：
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);
...
}
一个解决方案是使用持久化注解的 name 属性，例如 @Entity(name = "customer_contact")，但我想避免这样做，而是使用隐式映射。
英文:
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.

所需的属性是：
props.put("hibernate.physical_naming_strategy", SpringPhysicalNamingStrategy.class.getName());
props.put("hibernate.implicit_naming_strategy", SpringImplicitNamingStrategy.class.getName());

The needed properties are:
props.put("hibernate.physical_naming_strategy", SpringPhysicalNamingStrategy.class.getName());
props.put("hibernate.implicit_naming_strategy", SpringImplicitNamingStrategy.class.getName());
