springではクエリーキャッシュを使用します。

スプリング

spring 3を使用していますので、スペックはspring 3に基づいています。

まず、springにはデフォルト設定のクエリーキャッシュの設定がありません。springのxmlは以下の通りです。

主なBaseHDAの構成は以下の通りである。

package com.myweb.dao.hibernate;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;

/**
 * @author jsczxy2
 *
 */
@Repository
public class BaseHDao extends HibernateDaoSupport {
	
	Log log = LogFactory.getLog(getClass());
	
	@Autowired
	private SessionFactory sessionFactory;

}

更にspringのデフォルトの設定を見にきてキャッシュを調べて、実は違いはhibernature Templateとhibernature Templateの中のcacheQueriesでtrueに設定します！

このように、springのHibernature Templateを使ってcacheQueriesをtrueに設定するということは、springデフォルトではクエリキャッシュを開くという設定であることが分かります。クエリーキャッシュは、クエリ文の結果をキャッシュし、そのライフサイクルは関連するマッピングエンティティオブジェクトが変動するまで、変動があれば再チェックしてキャッシュします。
