这是我的Hibernate配置文件。错误堆栈跟踪为：

这是我的连接处理程序。java代码是：

public class ConnectionHandler {

    private static SessionFactory sesstioFactory;


    public static SessionFactory getSesstioFactory() {
        return sesstioFactory;
    }


    public static void setSesstioFactory(SessionFactory sesstioFactory) {
        ConnectionHandler.sesstioFactory = sesstioFactory;
    }


    public static void openConnection(){
        try{
            System.out.println("Trying to build session factory");
            sesstioFactory=new Configuration().configure().buildSessionFactory();
            System.out.println("Session factory built successfully");
        }
        catch (Exception e) {
            System.out.println("----------------Problem in opening connection--------------");
            e.printStackTrace();
        }
    }
    public static void closeConnection(){
        try{
            System.out.println("Trying to close session factory");
            sesstioFactory.close();
            System.out.println("Session factory closed successfully");
        }
        catch (Exception e) {
            System.out.println("----------------Problem in opening connection--------------");
            e.printStackTrace();
        }
    }

下面的代码段调用ConnectionHandler。java：

ConnectionHandler.openConnection(); // Calling for opening connection
                                            // for the first time
        SessionFactory sf = ConnectionHandler.getSesstioFactory();
        Session s = sf.openSession();
        Transaction t = s.beginTransaction(); 

我不知道为什么解析配置文件时会出现错误。我试着改变

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"到"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"

还包括所有所需的罐子。非常感谢。

在您的 Hibernate.cfg.xml文件，请尝试更改

<罢工> 对此:

编辑:

在我的原始答案中，我从我的映射文件中复制了DOCTYPE;我应该从配置文件中复制。感谢RAS指出这一点。

您的配置文件似乎正确。我使用的是相同的＜code＞DOCTYPE＜/code＞声明：

  
   <!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

  

对于映射文件，您可以尝试下面的DOCTYPE声明（如果您的不同）并确保没有拼写错误：

  
   <!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
