我是hibernate框架的新手。我做了一个示例项目来测试hibernate。我建立了这个项目。但是当我运行它时我得到了这个错误

org.hibernate.HibernateException: /hibernate.cfg.xml not found
at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:147)
at org.hibernate.cfg.Configuration.getConfigurationInputStream(Configuration.java:1405)
at org.hibernate.cfg.Configuration.configure(Configuration.java:1427)
at org.hibernate.cfg.AnnotationConfiguration.configure(AnnotationConfiguration.java:972)
at org.hibernate.cfg.AnnotationConfiguration.configure(AnnotationConfiguration.java:69)
at org.hibernate.cfg.Configuration.configure(Configuration.java:1414)
at org.hibernate.cfg.AnnotationConfiguration.configure(AnnotationConfiguration.java:966)

我放在项目主程序包中的 Hibernate.cfg.xml 文件。

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
    <hibernate-configuration>

            <session-factory>
                <property name="hibernate.dialect">
          org.hibernate.dialect.DerbyDialect
                </property>
                <property name="current_session_context_class">thread</property>
                <property name="show_sql">true</property>
                <property name="connection.pool_size">2</property>
                <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
       <!--<property name="htm2ddl.auto">create</property>-->
                <property name="hibernate.connection.driver_class">
          org.apache.derby.jdbc.ClientDriver
                </property>

       <!-- Assume test is the database name -->
                <property name="hibernate.connection.url">
          jdbc:derby://localhost:1527/NetworkDB
                </property>
                <property name="hibernate.connection.username">

                </property>
                <property name="hibernate.connection.password">

                </property>

       <!-- List of XML mapping files -->
       <!-- <mapping resource="Employee.hbm.xml"/>-->

            </session-factory>

    </hibernate-configuration>

我正在使用netbeans 7.0

2 个答案:

答案 0 :(得分:1)

根据DTD,<hibernate-configuration>应该有一个<session-factory>,但您已经宣布了两次。

关于第二个错误:

org.hibernate.HibernateException: /hibernate.cfg.xml not found

Hibernate在类路径的根目录中查找配置文件,因此请检查是否已将此文件放在类路径的根目录下。

因此,一旦构建项目,hibernate.cfg.xml文件应该在classes目录中。

在xml的第一行添加以下内容:

<?xml version="1.0" encoding="UTF-8"?>
