我想我找到了解决方案。
为了实现我的目标，我使用了hibernate.physical_naming_strategy配置，而不是hibernate.implicit_naming_strategy.
我创建了一个实现PhysicalNamingStrategy模拟原始部分功能的界面ImprovedNamingStrategy class:
package fms.util.hibernate;
import org.apache.commons.lang.StringUtils;
import org.hibernate.boot.model.naming.Identifier;
import org.hibernate.boot.model.naming.PhysicalNamingStrategy;
import org.hibernate.engine.jdbc.env.spi.JdbcEnvironment;
public class ImprovedNamingStrategy implements PhysicalNamingStrategy {
@Override
public Identifier toPhysicalCatalogName(Identifier identifier, JdbcEnvironment jdbcEnv) {
return convert(identifier);
}
@Override
public Identifier toPhysicalColumnName(Identifier identifier, JdbcEnvironment jdbcEnv) {
return convert(identifier);
}
@Override
public Identifier toPhysicalSchemaName(Identifier identifier, JdbcEnvironment jdbcEnv) {
return convert(identifier);
}
@Override
public Identifier toPhysicalSequenceName(Identifier identifier, JdbcEnvironment jdbcEnv) {
return convert(identifier);
}
@Override
public Identifier toPhysicalTableName(Identifier identifier, JdbcEnvironment jdbcEnv) {
return convert(identifier);
}
private Identifier convert(Identifier identifier) {
if (identifier == null || StringUtils.isBlank(identifier.getText())) {
return identifier;
}
String regex = "([a-z])([A-Z])";
String replacement = "$1_$2";
String newName = identifier.getText().replaceAll(regex, replacement).toLowerCase();
return Identifier.toIdentifier(newName);
}
}
创建此类后，我将配置更改为：
<entry key="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy" />
to this:
<entry key="hibernate.physical_naming_strategy" value="fms.util.hibernate.ImprovedNamingStrategy" />
现在一切正常。
该解决方案只涵盖了一小部分ImprovedNamingStrategy。在我的项目中，对于表映射和连接映射，我总是显式指定表或连接列的名称。我仅依赖列名的隐式名称转换。所以这个简单的解决方案对我来说是可以接受的。
这是我的 Spring 配置文件的完整示例：

我希望这个解决方案对某人有帮助。 :)
