sessionfactory创建：
private static SessionFactory sessionFactory ;
public static SessionFactory buildSessionFactory()
{
try
{
if (sessionFactory == null)
{
Configuration configuration = new Configuration().configure(SqliteCon.class.getResource("/hibernate.cfg.xml"));
StandardServiceRegistryBuilder serviceRegistryBuilder = new StandardServiceRegistryBuilder();
serviceRegistryBuilder.applySettings(configuration.getProperties());
ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
System.out.println(sessionFactory.isClosed());
}
return sessionFactory;
}
catch (Throwable ex)
{
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
调用sessionfactory：
public List<SessionMatrixBean> getAll()
{
List<SessionMatrixBean> smbList=null;
sessionFactory = SqliteCon.buildSessionFactory();
if(sessionFactory==null) System.out.println("-----------SESSIONFACTORY IS NULL-----------------");
try
{
session = sessionFactory.openSession();
session.beginTransaction();
query = session.createQuery("FROM SessionMatrixBean");
smbList =(ArrayList<SessionMatrixBean>) query.list();
// session.getTransaction().commit();
}
catch (Exception e)
{
System.err.println(e.getMessage());
}
finally
{
if(session!=null){if(session.isOpen()){session.flush();session.close();}}
if(sessionFactory!=null){if(!sessionFactory.isClosed()){sessionFactory.close();}}
}
return smbList;
}
将帖子 的hibernate.cfg.xml
<hibernate-configuration>
<session-factory>
<property name="hbm2ddl.auto">update</property>
<property name="show_sql">false</property>
<property name="format_sql">true</property>

<property name="connection.username"></property>
<property name="connection.password"></property>
<property name="connection.driver_class">org.sqlite.JDBC</property>
<mapping class="exam.bean.SessionMatrixBean" />
</session-factory>
