java - 如何使用 Spring 定义 Hibernate bean 的命名策略？

Question

我重写了所有 ImprovedNamingStrategy 方法并为它们设置了断点，但在 Debug模式下未调用这些方法。

我只有一个 hibernate 工厂，所以不可能因为其他实例而出错。

我认为，问题出在关键“hibernate.ejb.naming_strategy”还是不对？

    <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.springframework.org/schema/beans"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-4.2.xsd">
    <bean id="sqlSessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.${jdbc.dialect}</prop>
                <prop key="hibernate.globally_quoted_identifiers=true">true</prop>
                <prop key="hibernate.enable_lazy_load_no_trans">false</prop>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
                <prop key="hibernate.show_sql">{hibernate.show_sql}</prop>
                <prop key="hibernate.ejb.naming_strategy">
                com.stub.utilities.dao.sql.hibernate.LowerCaseNamingStrategy
                </prop>
            </props>
        </property>
        <property name="annotatedClasses"/>
    </bean>
</beans>

Answer 1

Hibernate 5 没有任何 ImprovedNamingStrategy。它使用 ImplicitNamingStrategy 和 PhysicalNamingStrategy 接口(interface)。严格来说，在Hibernate 5.1中有类ImprovedNamingStrategy，例如。但是您不能使用它来配置 SessionFactory。

设置ImplicitNamingStrategy的例子

  <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="implicitNamingStrategy">
      <bean class="com.github.fluent.hibernate.cfg.strategy.hibernate5.Hibernate5NamingStrategy">
        <property name="tablePrefix" value="spring_" />
      </bean>
    </property>
  </bean>

您也可以使用 hibernate.implicit_naming_strategy 和 hibernate.physical_naming_strategy 属性

<bean id="sqlSessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.implicit_naming_strategy">
                  com.stub.utilities.dao.sql.hibernate.ImplicitNamingStrategy
                </prop>
                <prop key="hibernate.physical_naming_strategy">
                  com.stub.utilities.dao.sql.hibernate.PhysicalNamingStrategy
                </prop>
            </props>
        </property>
        <property name="annotatedClasses"/>
    </bean>
</beans>
