ClassFormatError：类文件 javax/persistence/InheritanceType 中非本机或抽象方法中的缺失代码属性

尝试构建 sessionFactory 我的 hibernate.cfg.xml 文件时出现此错误：

<?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="hibernate.connection.url">jdbc:mysql://localhost:3306/carpool</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
        <mapping class="org.mathew.data.User"></mapping>
    </session-factory>
</hibernate-configuration>

我的 HibernateUtil 类：

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            return new AnnotationConfiguration().configure().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();
    }

}

您似乎在手动管理您的依赖项，您确实应该使用依赖项管理器（maven、ivy 和 ant 等）来确保您获得正确的依赖项（所有库都在其预期版本中）。由于您没有指定您正在使用的库的版本，因此可能存在几个问题：

  • 不兼容的持久化 API 版本与休眠
  • hibernate jar 的不兼容组合：您显然有一个 hibernate3 jar 和 hibernate-core，这似乎不正确。它看起来像是一个旧版本的 Hibernate 与更新的 jars 混合在一起。因此，如果 jar 在类路径中首先出现，则仅存在于最新版本中的类可能正在访问旧版本中的类。
