Java Hibernate 5.4.25二级缓存和扩展SingleToneCacheRegionFactory类

，可以将hibernate配置选项

hibernate.cache.region.factory\u class

设置为类值。这允许我扩展类

org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory

，并为集群应用程序实现所需的额外代码。然后，可以将这个实现的类引用为hibernate设置中的

hibernate.cache.region.factory\u类的配置值

spring-config.xml中的示例：

<prop key="hibernate.cache.use_second_level_cache">true</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
<prop key="hibernate.cache.region.factory_class">com.example.MySingletonEhCacheRegionFactory</prop>

我现在正试图升级到5.4.25版本，但是SingletoneCacheRegionFactory被移动到一个内部类，代码被修改

最重要的是，
hibernate.cache.region.factory\u类
config现在希望该类使用。这一点在报告中有所说明

例如：

<prop key="hibernate.cache.region.factory_class">ehcache-singleton</prop>       

任何对以上内容的了解都将不胜感激
 我认为应该扩展
org.hibernate.cache.ehcache.internal.SingletonEhcacheRegionFactory
类，但新类与
org.hibernate.cache.ehcache.SingletonEhcacheRegionFactory
略有不同，因此需要重写当前代码

如果您尝试扩展
net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory
，您将面临以下问题

关于如何引用它，它正在实现
org.hibernate.boot.registry.selector.StrategyRegistrationProvider
接口，如：

package my.package.MyStrategyRegistrationProviderImpl;

import java.util.ArrayList;
import java.util.List;

import org.hibernate.boot.registry.selector.SimpleStrategyRegistrationImpl;
import org.hibernate.boot.registry.selector.StrategyRegistration;
import org.hibernate.boot.registry.selector.StrategyRegistrationProvider;
import org.hibernate.cache.spi.RegionFactory;

/**
 * Makes the 1 contained region factory implementations available to the Hibernate
 * {@link org.hibernate.boot.registry.selector.spi.StrategySelector} service.
 */
public class MyStrategyRegistrationProviderImpl implements StrategyRegistrationProvider {

    @Override
    @SuppressWarnings("unchecked")
    public Iterable<StrategyRegistration> getStrategyRegistrations() {
        final List<StrategyRegistration> strategyRegistrations = new ArrayList<StrategyRegistration>( 1 );

        strategyRegistrations.add(
                new SimpleStrategyRegistrationImpl(
                        RegionFactory.class,
                        CustomSingletonEhCacheRegionFactory.class,
                        "custom-ehcache-singleton",
                        CustomSingletonEhCacheRegionFactory.class.getName(),
                        CustomSingletonEhCacheRegionFactory.class.getSimpleName(),
                        // legacy impl class name
                        "org.hibernate.cache.SingletonEhCacheRegionFactory",
                        "org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory"
                )
        );

        return strategyRegistrations;
    }
}

非常感谢。这似乎解决了我的问题。我能够在我的spring-config.xml文件中使用
“custom-ehcache singleton”
。所以
定制ehcache单例
。我的部分实现需要一些其他更改，特别是来自CacheImpl的更改。请参阅：。
<prop key="hibernate.cache.region.factory_class">myEhcache-singleton</prop>
