休眠4.x的二級緩存配置

Question

我在hibernate4中配置了ehcache，以下是我的配置

pom.xml

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-core</artifactId>
  <version>4.0.1.Final</version>
</dependency>

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-ehcache</artifactId>
  <version>4.0.1.Final</version>
</dependency>

休眠配置

configuration.setProperty("hibernate.cache.region.factory_class",
                "org.hibernate.cache.ehcache.EhCacheRegionFactory");
configuration.setProperty("hibernate.cache.region.factory_class",
                "org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory");
configuration.setProperty("hibernate.cache.use_second_level_cache", "true");
configuration.setProperty("hibernate.cache.use_query_cache", "true");

實體類

 @Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
@Cacheable




**Note : **
I did this configuration but  i am not getting any error, and ehcache is not working

請嘗試以下

configuration.setProperty("hibernate.cache.region.factory_class",
                "org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory");
configuration.setProperty("hibernate.cache.use_second_level_cache", "true");
configuration.setProperty("hibernate.cache.use_query_cache", "true");

ehcache.hibernate.cache.provider_configuration=classpath:ehcache.xml
