java - Hibernate 编译问题

Question

我必须使用 Hibernate 来制作我的项目。问题是我找不到解决问题的方法。我无法编译我的程序，因为我遇到了一些问题(我在输出控制台下方复制)

hibernate .cfg.xml:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration SYSTEM
    "classpath://org/hibernate/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
        <property name="connection.url">jdbc:hsqldb:hsql://localhost</property>
        <property name="connection.username">sa</property>
        <property name="connection.password"></property>
        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>
        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.HSQLDialect</property>
        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>
        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>
        <!-- Drop and re-create the database schema on startup -->
        <!-- <property name="hbm2ddl.auto">create</property> -->
        <mapping resource="events/Event.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

我的主类很简单:

        Session session = HibernateUtil.getSessionFactory().getCurrentSession();

        session.beginTransaction();

        Event theEvent = new Event();
        theEvent.settitle(title);
        theEvent.setdate(theDate);

        session.save(theEvent);

        session.getTransaction().commit();

当我尝试编译我的程序时，我得到这样的结果:

我该如何解决这个问题？

提前致谢!

编辑:你好!我再次更改了 meskobalazs(在 hibernate.cfg.xml 中)提到的内容。该程序继续运行，但仍然出现一些错误和错误:

Answer 1

改变这个

<!DOCTYPE hibernate-configuration SYSTEM
    "classpath://org/hibernate/hibernate-configuration-3.0.dtd">
<hibernate-mapping>

到

<!DOCTYPE hibernate-mapping SYSTEM
    "classpath://org/hibernate/hibernate-mapping-3.0.dtd">
<hibernate-mapping>

您引用了错误的 DTD。
