caching - spring4.3.x如何配置 'entityCacheStrategies'

Question

我正在从 spring3.x 迁移到 spring4.3.x。我在 bean 创建中使用 org.springframework.orm.hibernate5.LocalSessionFactoryBean 如下

    <bean id="sessionFactory"
      class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="annotatedClasses">
        <list>
            <value>com.example.person.domain.Person</value>
        </list>
    </property>

    <property name="mappingLocations">
        <list>
            <value>classpath*:com/example/person/domain/Person.hbm.xml</value>
        </list>
    </property>

    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
            <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
            <prop key="hibernate.cache.use_query_cache">true</prop>
            <prop key="hibernate.cache.provider_class">${cache.providerClass}</prop>
            <prop key="hibernate.generate_statistics">true</prop>
            <prop key="hibernate.memcached.dogpilePrevention">true</prop>
            <prop key="hibernate.memcached.servers">${cache.memcached.servers}</prop>
            <prop key="hibernate.memcached.keyStrategy">com.example.memcached.ExampleCacheStringKeyStrategy</prop>
            <prop key="hibernate.memcached.deviceAttributeDao.keyStrategy">com.googlecode.hibernate.memcached.HashCodeKeyStrategy</prop>
            <prop key="hibernate.memcached.EncodingDao.keyStrategy">com.googlecode.hibernate.memcached.HashCodeKeyStrategy</prop>
        </props>
    </property>

    <property name="entityCacheStrategies">
        <props>
            <prop key="com.example.person.domain.TestAttribute">read-write,_domain</prop>
        </props>
    </property>

    <property name="dataSource" ref="dataSource"/>
</bean>

我收到以下错误

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'entityCacheStrategies' of bean class [org.springframework.orm.hibernate5.LocalSessionFactoryBean]: Bean property 'entityCacheStrategies' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

我正在使用 spring-4.3.0.RELEASE。 LocalSessionFactoryBean 没有用于 entityCacheStrategies 的 setter。知道如何在 spring4.3.x 中支持它吗？

Answer 1

entityCacheStrategies/setEntityCacheStrategies()的用法已在 hibernate 5 中弃用。来自 org.hibernate.cfg.Configuration : setCacheConcurrencyStrategy(String clazz, String concurrencyStrategy) 的可能替代方案也不再使用。

但是，如果您愿意使用 hibernate 注释库配置缓存，请尝试 this approach这使得使用 CacheConcurrencyStrategy枚举器。
您可以申请适当的Concurrency策略在 Entity等级。

@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
public class Clazz{..}

请查找 CacheConcurrencyStrategy 的更多用法在 dev guide .
