ClassFormatError：方法中的Absent Code属性，在类文件javax / persistence / InheritanceType
中不是本机的或抽象的尝试构建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>
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();
}
}

您似乎手动管理依赖项，您应该使用依赖项管理器（maven，ivy with ant等）以确保获得正确的依赖项（所有libs 在其预期版本中< / em>的）。由于您未指定所使用的库的版本，因此存在以下几种可能的问题：
