Question

我尝试使用Hibernate连接到我的数据库。但是当我构建SessionFactory时，它总是抛出一个JDBCCOnnectionException：调用Driver＃connect错误

Exception in thread "main" org.hibernate.exception.JDBCConnectionException: Error calling Driver#connect

at HibernateTest.main(HibernateTest.java:19)

代码：

Configuration cfg = new Configuration().configure("hibernate.cfg.xml");         
    StandardServiceRegistryBuilder sb = new StandardServiceRegistryBuilder();
    sb.applySettings(cfg.getProperties());
    StandardServiceRegistry standardServiceRegistry = sb.build();                   
    SessionFactory sessionFactory = cfg.buildSessionFactory(standardServiceRegistry); //<-- Exception here
    System.err.println("configuration done");

hibernate.cfg.xml文件已完成并成功加载。我还在我的构建路径中添加了mysql-connector-java-5.1.29.bin.jar。

这是配置文件的问题。

检查你的Sid in

hibernate.cfg.xml file

对于Oracle Express Edition：

<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:xe</property>

对于Oracle Enterprise Edition：

<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property>
