我正在将项目从 Spring-4.1.6.RELEASE 升级到 Spring-4.2.1.RELEASE，Hibernate（核心和 Ehcache）从 4.3.9.Final 升级到 5.0.1.Final。

在 Spring-4.1.6.RELEASE 中有一个方法

org.springframework.orm.hibernate4.LocalSessionFactoryBean.setCacheRegionFactory(RegionFactory cacheRegionFactory)

但是在 Spring 4.2.1.RELEASE 中，类中没有这样的方法

org.springframework.orm.hibernate5.LocalSessionFactoryBean

因此，当我在休眠会话工厂 bean 中设置属性以启用二级缓存时

<prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>

抛出以下错误：

WARN : org.springframework.beans.factory.support.DefaultListableBeanFactory - Bean creation exception on FactoryBean type check: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDao' defined in class path resource [application-context.xml]: Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in class path resource [application-context.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [application-context.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'cacheRegionFactory' of bean class [org.springframework.orm.hibernate5.LocalSessionFactoryBean]: Bean property 'cacheRegionFactory' is not writable or has an invalid setter method.

如何在 Spring-4.2.1.RELEASE 和 Hibernate-5.0.1.FINAL 中配置二级缓存？Hibernate-5 中启用二级缓存的代码替换是什么？

请帮助解决此迁移问题。先谢谢了。

tl;dr 版本：将 HibernateTransactionManager 类的包从 org.springframework.orm.hibernate4 更改为 org.springframework.orm.hibernate5。

我可以通过改变这个来完成这个工作：

<!-- Set up default hibernate properties. -->
<bean id="hibernateProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
    <property name="properties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.cache.use_second_level_cache">true</prop>
            <prop key="hibernate.cache.use_query_cache">true</prop>
        </props>
    </property>
</bean>

<bean id="cacheRegionFactory" class="org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory">
    <constructor-arg index="0" ref="hibernateProperties" />
</bean>

<bean id="sessionFactory" class="org.nrg.framework.orm.hibernate.AggregatedAnnotationSessionFactoryBean"
      p:cacheRegionFactory-ref="cacheRegionFactory" p:dataSource-ref="dataSource"
      p:hibernateProperties-ref="hibernateProperties" p:namingStrategy-ref="namingStrategy" />

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager" p:sessionFactory-ref="sessionFactory" />

对此：

<!-- Set up default hibernate properties. -->
<bean id="hibernateProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
    <property name="properties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.cache.use_second_level_cache">true</prop>
            <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</prop>
            <prop key="hibernate.cache.use_query_cache">true</prop>
        </props>
    </property>
</bean>

<bean id="sessionFactory" class="org.nrg.framework.orm.hibernate.AggregatedAnnotationSessionFactoryBean"
      p:dataSource-ref="dataSource" p:hibernateProperties-ref="hibernateProperties" p:physicalNamingStrategy-ref="namingStrategy" />

<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager" p:sessionFactory-ref="sessionFactory" />

这里最大的变化是：

<prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</prop>

你已经完成了这部分。

其他变化是：

  • 将 p:namingStrategy-ref 更改为 p:physicalNamingStrategy-ref （这需要更改我的自定义命名实现，但非常简单）
  • 删除 SingletonEhCacheRegionFactory bean 声明
  • 删除 p:cacheRegionFactory-ref 属性设置
  • 将 HibernateTransactionManager 类的包从 org.springframework.orm.hibernate4 更改为 org.springframework.orm.hibernate5

我认为最后一个可能是你需要改变的关键。

总的来说，我更喜欢通过 bean 设置缓存区域管理器的类型安全能力，而不是自由格式的属性值设置，但这会修补我们，直到我能找到另一种方法。
