加载持久会话时使用Hibernate进行群集：严重：IOException:java.io.InvalidObjectException:找不到SessionFactory

我使用Hibernate处理单个Tomcat节点，但当我尝试在集群中运行时，会出现以下错误：

SEVERE: IOException while loading persisted sessions: java.io.InvalidObjectException: Could not find a SessionFactory [uuid=158c1e24-039b-4406-9a9b-cebb836100d1,name=null]

这是我的HibernateUtil类，名为RecordingHibernateUtil：

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();
}
}

从internet搜索中，它听起来像是试图序列化Hibernate SessionFactory，为了防止这种情况，建议使用JNDI查找来获取SessionFactory。这是正确的吗？我不知道它为什么要序列化SessionFactory。（现在我将SessionFactory存储在HibernateUtil类中的一个静态变量中……我更愿意以这种方式保存它。）

真的有必要使用JNDI吗？我该怎么做呢？我需要一个既适用于Tomcat又适用于JBoss的解决方案（最好），或者每个都需要一个单独的解决方案。

问题是，在某个时候，您的http会话保留了对SessionFactory的引用，这是没有意义的。 SessionFactory是从每个Hibernate会话引用的，所以我想您应该在http会话中引用Hibernate会话。。。这很糟糕

请记住：

• http会话是一个长期存在的对象（多请求-响应循环）
• hibernate会话是短时间的活动对象（即使可以完成：在多个请求期间尝试重用同一个hibernate会话是相当复杂的）

因此，您必须在Http会话中找到对Hibernate会话的引用：使用调试器并探索Http会话的内容
