用SchemaExport自动建表后台报错：
Exception in thread "main" java.lang.IncompatibleClassChangeError: class org.hibernate.cfg.ExtendedMappings has interface org.hibernate.cfg.Mappings as super class

Create.java:



package com.hibernate.crud;



import org.hibernate.cfg.AnnotationConfiguration;

import org.hibernate.tool.hbm2ddl.SchemaExport;



public class Create {

	public static void main(String[] args) {

		AnnotationConfiguration ac = new AnnotationConfiguration().configure();

		SchemaExport se = new SchemaExport(ac);

		se.create(true, true);

	}

}

hibernate.cfg.xml:



<?xml version='1.0' encoding='utf-8'?>
