本文介绍了一种在Hibernate中使用的自定义命名策略实现，通过NightNamingStrategy类为数据库表和字段提供统一的前缀，并将所有名称转换为大写。此外，还展示了如何在Spring配置文件中设置该命名策略。

import org.hibernate.cfg.ImprovedNamingStrategy;

@SuppressWarnings("serial")
public class NightNamingStrategy extends ImprovedNamingStrategy
{
	private String tablePrefix = "t_";

	private String columnPrefix = "c_";

	@Override
	public String collectionTableName(String ownerEntity, String ownerEntityTable, String associatedEntity, String associatedEntityTable, String propertyName)
	{
		return tableName(ownerEntityTable + "_" + associatedEntityTable);
	}

	@Override
	public String propertyToColumnName(String propertyName)
	{
		return (this.columnPrefix + super.propertyToColumnName(propertyName)).toUpperCase();
	}

	@Override
	public String classToTableName(String className)
	{
		return (this.tablePrefix + super.classToTableName(className)).toUpperCase();
	}

}

	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!--配置命名规则-->
		<property name="namingStrategy">
			<bean class="naming.NightNamingStrategy"></bean>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.hbm2ddl.auto">${hbm2ddl.auto}</prop>
				<prop key="hibernate.dialect">${hibernate.dialect}</prop>
				<prop key="hibernate.show_sql">${show_sql}</prop>
				<prop key="hibernate.format_sql">${format_sql}</prop>
				<!--<prop key="hibernate.current_session_context_class">thread</prop>-->
			</props>
		</property>
		<property name="packagesToScan" value="tpcframework" />
	</bean>
