ClassFormatError：在方法缺席代碼屬性，是不是在類文件本地或抽象的javax /持久/ InheritanceType冬眠buildSessionFactory ClassFormatError：
我得到這個錯誤時，嘗試構建SessionFactory的 我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="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HibernateUtil類：
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();
}
}

發佈確切的異常_and_ stacktrace的初學者。但無論如何，它看起來像一個依賴問題，在你的類路徑中有多個版本的jar。 –
好吧，我發佈stacktrace :) – Mathew1990
我添加了persistence-api依賴關係，並出現相同的錯誤 – Mathew1990
