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

Question

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
             "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
<session-factory name="sessionFactory">

    <property name="hibernate.connection.username">best</property> 
    <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> 
    <property name="hibernate.show_sql">false</property> 
    <mapping resource="Registration.hbm.xml"/> 
</session-factory> 
</hibernate-configuration> 

这是我的hibernate配置文件。错误堆栈跟踪是：

我ConnectionHandler.java代码：

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(); 

我不知道为什么它的显示错误解析配置文件。我试图改变到 “http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd”>

也包括

“http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd” 所有必需的罐子。谢谢！

在你 hibernate.cfg.xml文件，尝试改变

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

本：

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

编辑：

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

你的配置文件似乎是正确的。我使用的是相同的DOCTYPE声明：

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

而对于映射文件，你可以试试下面DOCTYPE声明（如果你是不同的），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">
