Java hibernate buildSessionFactory类格式错误：

ClassFormatError:类文件javax/persistence/InheritanceType中非本机或抽象的方法中缺少代码属性

我在尝试构建sessionFactory时遇到此错误 我的hibernate.cfg.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.username">mateusz</property>
        <property name="hibernate.connection.password">mateusz123</property>

        <property name="show_sql">true</property>
        <mapping class="org.mathew.data.User"></mapping>
    </session-factory>
</hibernate-configuration>

我无法上传图像：）

如果有人能帮忙，我将不胜感激。

谢谢！：）

您似乎是在手动管理依赖项，您真的应该使用依赖项管理器（maven、ivy with ant等）来确保获得正确的依赖项（预期版本中的所有LIB）。由于未指定正在使用的库的版本，因此可能存在以下几个问题：

• 与hibernate不兼容的持久性api版本
• HibernateJAR的不兼容组合：显然，您有一个Hibernate3JAR和HibernateCore，这似乎不对。它看起来像是一个旧版本的Hibernate，混合了更新的JAR。因此，如果jar位于类路径的第一位，则仅存在于最新版本中的类可能正在访问旧版本中的类

为初学者发布确切的异常和stacktrace。但无论如何，它看起来像是一个依赖性问题，在您的类路径上有一个jar的多个版本
