java hibernate。cfg。找不到xml（eclipse）

Question

我今天开始使用Hibernate，并测试了一个简单的示例，但我发现了一个错误：Hibernate。cfg。找不到xml。 我让它冬眠。cfg。src文件夹中的xml文件，其内容如下：

    <?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>
    <!-- Database connection settings -->
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="connection.url">jdbc:mysql://localhost:3306/test</property>
    <property name="connection.username">test</property>
    <property name="connection.password">test</property>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">1</property>

    <!-- SQL dialect -->
    <property name="dialect">org.hibernate.dialect.MySQLDialect</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.internal.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">update</property>

    <mapping resource="com/mycompany/model/Product.hbm.xml"/>

  </session-factory>
</hibernate-configuration>

我把冬眠球放进洞里。util文件夹（src/util）下的java文件，下面是它的内容

    package util;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil
{
    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory()
    {
        try
        {
            // Create the SessionFactory from hibernate.cfg.xml
            return new Configuration().configure("hibernate.cgf.xml").buildSessionFactory();
        }
        catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public static void shutdown() {
        // Close caches and connection pools
        getSessionFactory().close();
    }
}

我还将jar添加到构建路径中

我的班级考试。爪哇：

    import ...


public class Test {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        ProductDao pd = new ProductDao();

        try {

            Product p = new Product("PC", 1000L);

            pd.add(p);

        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }

}

添加方法：

公共无效添加（产品p）{

Session session = HibernateUtil.getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
session.beginTransaction();
session.save(p);
tx.commit();

}

提前谢谢

Answer 1

如果是Maven项目，只需添加cfg即可。eclips中/src/main/resources中的xml文件

Answer 2

如果使用maven，请尝试将其放入

/src/main/resources

如果使用简单的eclipse项目（不带maven），则将其放在项目根目录中（不在src中）

您还拼错了源文件中的文件名

return new Configuration().configure("hibernate.cgf.xml").buildSessionFactory();

一定是

hibernate.cfg.xml
