単一の Tomcat ノードで Hibernate を使用していますが、クラスターで実行しようとすると、次のエラーが発生します。
SEVERE: IOException while loading persisted sessions: java.io.InvalidObjectException: Could not find a SessionFactory [uuid=158c1e24-039b-4406-9a9b-cebb836100d1,name=null]

RecordingHibernateUtil と呼ばれる私の HibernateUtil クラスは次のとおりです。
public class RecordingHibernateUtil {
public static final String CONFIG_FILENAME = "hibernate-recording.cfg.xml";
public static final String RECORDING_DB_URL = "recording.db.url";
public static final String RECORDING_DB_DRIVER = "recording.db.driver";
public static final String RECORDING_DB_USERNAME = "recording.db.username";
public static final String RECORDING_DB_PASSWORD = "recording.db.password";
private static SessionFactory sessionFactory = null;
public static void buildSessionFactory() {
if (sessionFactory != null) {
//Already configured
return;
}
Properties props;
try {
props = DBConfiguration.getInstance().getProperties();
} catch (Exception e) {
throw new RuntimeException(e);
}
Configuration config = new Configuration().configure(CONFIG_FILENAME);
config.setProperty("hibernate.connection.url",
props.getProperty(RECORDING_DB_URL,
props.getProperty(DBConfiguration.DB_URL)));
config.setProperty("hibernate.connection.driver_class",
props.getProperty(RECORDING_DB_DRIVER,
props.getProperty(DBConfiguration.DB_DRIVER)));
config.setProperty("hibernate.connection.username",
props.getProperty(RECORDING_DB_USERNAME,
props.getProperty(DBConfiguration.DB_USERNAME)));
config.setProperty("hibernate.connection.password",
props.getProperty(RECORDING_DB_PASSWORD,
props.getProperty(DBConfiguration.DB_PASSWORD)));
try {
sessionFactory = config.buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
public static void shutdown() {
// Close caches and connection pools
getSessionFactory().close();
}
}
インターネット検索から、Hibernate SessionFactory をシリアライズしようとしているように聞こえました。これを防ぐために、JNDI ルックアップを使用して SessionFactory を取得することが提案されました。これは正しいです？とにかくSessionFactoryをシリアライズしようとしている理由がわかりません。(現在、SessionFactory を HibernateUtil クラスの静的変数に格納しています... この方法を維持したいです。)
JNDI を使用することは本当に必要ですか? どうすればこれを行うことができますか？Tomcat と JBoss (できれば) の両方で機能するソリューション、またはそれぞれに個別のソリューションが必要です。
