現在、Ehcache を第 2 レベルのキャッシュとして使用して H2 データベースで休止状態を構成し、2 つのテストを実行しました (アイテムを 10000 回クエリして、キャッシュがどのように機能するかを確認します)。ただし、キャッシュは機能しませんでした。ベンチマーク時間は、ehcache なしのテストと比較して変化しませんでした。統計によると、キャッシュのサイズが 1 である (アイテムがクエリされた) にもかかわらず、まったくヒットしなかったことが示されました。

[  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 統計 (sessionFactory.getStatistics().getSecondLevelCacheStatistics("Location")):

SecondLevelCacheStatistics[hitCount=0,missCount=0,putCount=0,elementCountInMemor‌​y=1,elementCountOnDisk=1,sizeInMemory=760]

これが私の構成です：

ehcache を有効にした Hibernate 構成:

    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 構成:

<ehcache>
<diskStore path="c:/_cached"/>
<cache
    name="org.hibernate.cache.StandardQueryCache"
    maxEntriesLocalHeap="5"
    eternal="false"
    timeToLiveSeconds="120"

<cache
    name="Location"
    maxElementsInMemory="10000"

    diskPersistent="false"
    diskExpiryThreadIntervalSeconds="120"
    memoryStoreEvictionPolicy="LRU"/>
</ehcache>

データベース クラス:

import org.hibernate.annotations.*;

import javax.persistence.*;
import javax.persistence.Entity;
import javax.persistence.Table;
import java.io.Serializable;

@Entity
@Table(name = "Location")
@org.hibernate.annotations.Cache(region = "Location", usage = CacheConcurrencyStrategy.READ_WRITE)

    @Column(name = "Position", nullable = false)
    private Geometry position;

    //getters and setters are ommited

テストコード:

@Test
public void testQueryCache(){
    int size = 10000;
    Location lo = null;
    long startTime = System.currentTimeMillis();
    Session currentSession = sessionFactory.openSession();
    for (int i = 0; i< size ; i++){
        Transaction transaction = currentSession.beginTransaction();
        lo = (Location) currentSession.createCriteria(Location.class)

    System.out.println(cache.getStatistics().toString());

    SecondLevelCacheStatistics statistics = sessionFactory.getStatistics().getSecondLevelCacheStatistics("Location");
    System.out.println(statistics.toString());
}

@Test

    }

    long stopTime = System.currentTimeMillis();

私が間違っていることを理解するのを手伝ってください!!! :(

返事が遅くなりましたが、

追跡したい要素を追加statistics="true"してみてください。また、hibernate.cfg.xml<cache>に追加 します。<property name="hibernate.generate_statistics">true</property>

これをすばやくスキャンするだけですが、Hibernateを使用するように構成しますが、を使用するnet.sf.ehcache.hibernate.EhCacheRegionFactoryのではなく、singletonを使用しCacheManager.getInstance()ます... Hibernate統計を介してキャッシュアクティビティを監視しようとしましたか？実際にCacheManageHibernateと同じものを使用しているかどうか疑問に思います...

やってみました：

sessionFactory.getCurrentSession().get(Location.class, 86);

基準クエリを使用する代わりに? Hibernate は、@Id によるオブジェクトのロードでのみ第 2 レベルのキャッシュにヒットするため、セッションで get/load を使用することを理解しています。

Criteria をキャッシュ可能にする場合:

sessionFactory.getCurrentSession.createCriteria().setCacheable(true).uniqueResult();

エンティティとクエリ キャッシュを有効にすると、そのクエリを実行するたびに第 2 レベルのキャッシュにヒットします。
