Tomcat複数のアプリ、ehcacheはうまく動作しません

Question

私はTomcatに複数の同じアプリを起動しています（異なるコンテンツを表示していますが、コードは同じです）。これらのAppsはHibernateとehcacheを使用します。

問題は：singelアプリケーションが期待どおりに動作します。もう1つを追加すると、nullpointerexceptionですべてがクラッシュします。

構成は次のとおりです。

 // Caching 
     cfg.setProperty("hibernate.cache.use_second_level_cache", "true"); 
     cfg.setProperty("hibernate.cache.provider_class", "org.hibernate.cache.EhCacheProvider"); 
     cfg.setProperty("hibernate.cache.region.factory_class", "org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory"); 
     cfg.setProperty("net.sf.ehcache.configurationResourceName", "com/gfop/util/hibernate/ehcache.xml"); 
     // Query Caching 
     cfg.setProperty("hibernate.cache.use_query_cache", "true"); 
     cfg.setProperty("hibernate.c3p0.statementCacheNumDeferredCloseThreads", "1"); 

これはスタックトレースです：

あなたは今までこのようなものを経験したことがありますか？あなたはこれを解決する方法を知っていますか？

Answer 1

SingletonEhCacheRegionFactoryを使用する場合は、EhCacheRegionFactoryを使用してください。今シングルトンしか持っていないので、別のインスタンスを得ることができません。一重です:) EhCacheRegionFactoryに変更し、別のインスタンスを取得できるようにします。
