目前，我使用 Ehcache 作为二级缓存将 H2 数据库配置为 Hibernate 以运行 2 次测试(查询项目 10000 次以查看缓存如何工作)，但是缓存不起作用。与没有 ehcache 的测试相比，基准时间没有改变。统计数据显示，即使缓存的 size = 1(该项目被查询)，它也根本没有被命中:
[ name = Location cacheHits = 0 onDiskHits = 0 offHeapHits = 0 inMemoryHits = 0 misses = 0 onDiskMisses = 0 offHeapMisses = 0 inMemoryMisses = 0 size = 1 averageGetTime = 0.0 evictionCount = 0 ]
Hibernate 统计信息(sessionFactory.getStatistics().getSecondLevelCacheStatistics("Location")):
SecondLevelCacheStatistics[hitCount=0,missCount=0,putCount=0,elementCountInMemory=1,elementCountOnDisk=1,sizeInMemory=760]
这是我的配置:
Maven 依赖项:

启用 ehcache 的 Hibernate 配置:
Configuration cfg = new Configuration()
.addAnnotatedClass(Location.class)
.setProperty("hibernate.connection.driver_class", dbConfig.getH2JdbcDriverName())
.setProperty("hibernate.connection.url", dbConfig.getDbUrl())
.setProperty("hibernate.connection.username", dbConfig.getUserName())
.setProperty("hibernate.connection.password", dbConfig.getPassword())
.setProperty("javax.persistence.validation.mode", "NONE")
.setProperty("hibernate.cache.use_second_level_cache", "true")
.setProperty("hibernate.cache.use_query_cache", "true")
.setProperty("hibernate.cache.region.factory_class", "org.hibernate.cache.ehcache.EhCacheRegionFactory");
sessionFactory = cfg.buildSessionFactory();
Ehcache xml配置:
<ehcache>
<diskStore path="c:/_cached"/>
<cache

数据库类:

}
long stopTime = System.currentTimeMillis();
Assert.assertNotNull(lo);
System.out.println(String.format("\t %d ms", stopTime - startTime));
Cache cache = CacheManager.getInstance().getCache("Location");
System.out.println(cache.getStatistics().toString());
SecondLevelCacheStatistics statistics = sessionFactory.getStatistics().getSecondLevelCacheStatistics("Location");
System.out.println(statistics.toString());
}
@Test

请帮我弄清楚我做错了什么!!! :(
非常感谢!!!
