Hibernate映射错误：MappingException：一个AnnotationConfiguration实例 [英] Hibernate Mapping Error: MappingException: An AnnotationConfiguration instance

问题描述

我有Hibernate.I一个项目试图读取配置文件hibernate.cfg和得到这个错误：

I have a project with Hibernate.I tried to read the configuration file hibernate.cfg and got this error:

 Error creando una factoria de session.org.hibernate.MappingException: An AnnotationConfiguration instance is required to use <mapping class="com/david/Categoria"/>
jun 04, 2013 10:19:26 AM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: El Servlet.service() para el servlet [ControladorLibros] en el contexto con ruta [/App01HTML] lanzó la excepción [La ejecución del Servlet lanzó una excepción] con causa raíz
org.hibernate.MappingException: An AnnotationConfiguration instance is required to use <mapping class="com/david/Categoria"/>

    at org.hibernate.cfg.Configuration.configure(Configuration.java:1338)
    at com.david.HibernateHelper.buildSessionFactory(HibernateHelper.java:13)

我的配置文件是如此的简单：

my configuration file is so simple:

<?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>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost/arquitecturajava</property>
        <property name="connection.username">root</property>
        <property name="connection.password">root</property>
        <property name="connection.pool_size">5</property>
        <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
        <property name="show_sql">true</property>
        <mapping class="com/david/Categoria"></mapping>
        <mapping class="com/david/Libro"></mapping>
    </session-factory>
</hibernate-configuration>

鸵鸟政策接受映射班线。

don´t accept mapping class lines.

创建与此类似code去配置：

I create de configurations similar to this code:

private static SessionFactory buildSessionFactory() 
    {
        try
        {

            return new Configuration().configure().buildSessionFactory(); 
        }
        catch (Throwable ex) 
        {
            System.err.println("Error creando una factoria de session." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

和我的项目库是：

任何想法？

推荐答案

的问题是库。
这是解决方案：

The problem was of libraries. This is the solutions:
