我做錯了什麼?在運行主類後,我在控制檯中查看如下面的當前屏幕截圖,控制檯繼續工作,沒有任何反應。不能用Hibernate連接postgreSQL(Eclipse)

的hibernate.cfg.xml:

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC 
"-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
    <session-factory> 
    <property name="connection.driver_class">org.postgresql.Driver</property> 
    <property name="connection.url">jdbc:postgresql://localhost:5432/Gillie_PL</property> 
    <property name="connection.username">postgres</property> 
    <property name="connection.password">postgres</property> 
    <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property> 
    <property name="show_sql">true</property> 
    <property name="hbm2ddl.auto">update</property> 
    </session-factory> 
</hibernate-configuration> 

hibernateUtil.class:

package hibernateConn; 
import org.hibernate.SessionFactory; 
import org.hibernate.boot.registry.StandardServiceRegistryBuilder; 
import org.hibernate.cfg.Configuration; 
public class HibernateUtil { 
    private static SessionFactory sessionFactory = null; 
    static { 
    Configuration cfg = 
     new Configuration().configure("/hibernateConn/hibernate.cfg.xml"); 
     StandardServiceRegistryBuilder builder = 
     new StandardServiceRegistryBuilder() 
     .applySettings(cfg.getProperties()); 
     sessionFactory = cfg.buildSessionFactory(builder.build()); 
    } 

public static SessionFactory getSessionFactory(){ 
    return sessionFactory; 
} 

}

Main.Class:

package hibernateConn; 
import org.hibernate.SessionFactory; 
public class Main { 
    public static void main(String[] args) { 
    SessionFactory sessionFactory = HibernateUtil.getSessionFactory(); 
    } 
} 

後,我跑Main.class我有控制檯:

而就是這樣。沒有更多,該程序繼續工作,沒有任何反應,就好像遞歸發生......也許我沒有正確指定xml中的設置?

我重寫了HibernateUtil.class,它一切正常。這個問題可以封閉 – smelyjtest

我改寫了HibernateUtil.class:

static { 
    try{ 
     sessionFactory = new Configuration().configure("/hibernateConn/hibernate.cfg.xml").buildSessionFactory(); 
    }catch(Throwable ex){ 
     System.err.println("++++Initial SessionFactory creation failed.++++: " + ex); 
     ex.printStackTrace(); 
    } 
} 

public static SessionFactory getSessionFactory(){ 
    return sessionFactory; 
} 

和它的所有工作。這個問題可以結束。
