在Maven的Web项目中用Main函数测试Hibernate_main方法测试hibernate-优快云博客

本文介绍了如何在Maven构建的Web项目中通过Main函数来测试Hibernate。在非Web环境下，测试代码通常可以直接运行，但在Web项目中，由于环境依赖，直接运行Main函数会遇到报错。

1. 编写Main测试Hibernate代码(与非Web项目一样)

<pre name="code" class="java">public class HibernateTest {	 
	public static void main(String[] args) {
		Configuration conf = new AnnotationConfiguration().configure();
		SessionFactory factory = conf.buildSessionFactory();
		Session session = factory.openSession();
		session.beginTransaction();
		
		List<Req> l = (List<Req>)session.createCriteria(Req.class).list();
		System.out.println(l.size());
		
		session.getTransaction().commit();
		session.close();		
	}
}

Run报错：

INFO: HHH000040: Configuration resource: /hibernate.cfg.xml
Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found

2. 编写 hibernate.cfg.xml，并移动到 /target/classes 目录下面去(由于每次Maven Clean后，会被清理掉，所以可以手动复制过去)

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