是不是沒配置映射關系？

問題出在哪兒啦?。?br />

建議你改用hibernate4.2的版本，否則會出現各種程度問題

配合樓主拿個積分~~~

好吧，我自己找到問題了

import?org.hibernate.Session;
import?org.hibernate.SessionFactory;
import?org.hibernate.cfg.Configuration;
import?org.hibernate.service.ServiceRegistry;
import?org.hibernate.service.ServiceRegistryBuilder;
import?org.junit.Test;

public?class?TestStudents?{

	@Test
	public?void?testSchemaExport(){
		//創建配置對象
		Configuration?config=new?Configuration().configure();
		//創建服務注冊對象
		ServiceRegistry?serviceRegistry=new?ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
		//創建SessionFactory
		SessionFactory?sessionFactory=config.buildSessionFactory(serviceRegistry);
		//創建session對象
		Session?session=sessionFactory.getCurrentSession();
		//創建SchemaExport對象
		SchemaExport?export?=?new?SchemaExport(config);
		
		
	}
}
