这是我的hibernate配置文件。错误堆栈跟踪是：

我的ConnectionHandler.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();
        }
    }

以下代码段调用ConnectionHandler.java：

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

我不知道为什么它显示错误解析配置文件。我试过改变

“http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd”改为 “http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd” ＆GT;

还包括所有必需的罐子。谢谢！

~~在hibernate.cfg.xml文件中，尝试更改~~

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

~~到此：~~

<击> <!DOCTYPE hibernate-mapping SYSTEM "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

修改：

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

您的配置文件似乎正确无误。我使用相同的DOCTYPE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">

无法解析配置：/hibernate.cfg.xml hibernate.sourceforge.net
