Java 升级到Hibernate 4.3.4 main方法永不终止JVM未完成
我必须从Java 升级到Hibernate 4.3.4 main方法永不终止JVM未完成,java,multithreading,hibernate,jpa,Java,Multithreading,Hibernate,Jpa,我必须从hibernate4.2.3升级到hibernate4.3.4来测试一些jpa2.1规范。我只更改了这行code 前一行: final org.hibernate.service.ServiceRegistry serviceRegistry = new org.hibernate.service.ServiceRegistryBuilder().applySettings(hibConfiguration.getProperties()).buildServiceRegistry();
hibernate4.2.3
升级到hibernate4.3.4
来测试一些jpa2.1
规范。我只更改了这行code
前一行:
final org.hibernate.service.ServiceRegistry serviceRegistry = new org.hibernate.service.ServiceRegistryBuilder().applySettings(hibConfiguration.getProperties()).buildServiceRegistry();
新添加的代码行
final org.hibernate.service.ServiceRegistry serviceRegistry = new org.hibernate.boot.registry.StandardServiceRegistryBuilder().applySettings(hibConfiguration.getProperties()).build();
问题是,我有一个主要方法只用于测试一些标准API
,但是主要方法
永远不会在最新的Hibernate版本中完成
我检索了正在运行的线程,最新版本的线程如下所示
ThreadList:
[threadID:]2 [threadName:] Reference Handler [isDaemon:] true [isAlive:] true
[threadID:]3 [threadName:] Finalizer [isDaemon:] true [isAlive:] true
[threadID:]4 [threadName:] Signal Dispatcher [isDaemon:] true [isAlive:] true
[threadID:]5 [threadName:] Attach Listener [isDaemon:] true [isAlive:] true
[threadID:]10 [threadName:] Abandoned connection cleanup thread [isDaemon:] true [isAlive:] true
[threadID:]11 [threadName:] pool-1-thread-1 [isDaemon:] false [isAlive:] true
[threadID:]1 [threadName:] main [isDaemon:] false [isAlive:] true
与以前的版本相比,这个线程是新的
[threadID:]11 [threadName:] pool-1-thread-1 [isDaemon:] false [isAlive:] true
根据规范,不是守护进程
No, it is not. The virtual machine terminates if the last non-daemon thread has finished. It doesn't have to be the main thread.
我想这条线至少不会在5分钟内完成
问题只出现在创建HibernateSessionFactory时。
public static void main(String[] args)
{
HibernateHandler handler = new HibernateHandler(true);//creates the HibernateSessionFactory
return;//JVM not finish at this point
}
我希望我的JVM以main方法finish终止
我做错了什么..要了解线程在做什么,可以进行线程转储,例如,在调试模式下从eclipse运行程序,然后挂起线程
但是在您的特定情况下,您应该尝试调用。新的
ServiceRegister
似乎没有关闭
,已销毁
当会话工厂
关闭时,您必须在调用时自行销毁
getSessionFactory.close().
我的新Hibernate代码
final Configuration hibConfiguration = new Configuration().configure(yourCFGPath);
final org.hibernate.service.ServiceRegistry serviceRegistry = new org.hibernate.boot.registry
.StandardServiceRegistryBuilder().
applySettings(hibConfiguration.getProperties()).build();
hibConfiguration.setSessionFactoryObserver(new SessionFactoryObserver()
{
@Override
public void sessionFactoryCreated(SessionFactory factory){}
@Override
public void sessionFactoryClosed(SessionFactory factory)
{
((StandardServiceRegistryImpl)serviceRegistry).destroy();
}});
final org.hibernate.SessionFactory factory = hibConfiguration.buildSessionFactory(serviceRegistry);
以后你得打电话
session.getSessionFactory().close();
我希望真的能帮助别人。非常感谢。我对此一无所知。为什么hibernate的人总是不喜欢这些东西,并且不提供关于新实现的信息(4.1、4.2、4.3…)。?有空的javadocs很难再次感谢你!
