HibernateException：Unable to get the default Bean Validation factory

今天用Hibernate出现了一个异常：org.hibernate.HibernateException: Unable to get the default Bean Validation factory

以前用的时候怎么没发现过呢？在网上找到了答案！

我就是映射一下看看:

@Test
	public void testSchemaExport() {
		new SchemaExport(new Configuration().configure()).create(true, true);
	}

就出现了真么个异常:

在这篇博客找到了答案，解决了，感谢！http://blog.csdn.net/huangbiao86/article/details/6594350

详细情况看这篇博客，写的很好

原来只要加上下面的代码就可以了：

    <property name="javax.persistence.validation.mode">none</property>  

javax.persistence.validation.mode默认情况下是auto的，就是说如果不设置的话它是会自动去你的classpath下面找一个bean-validation**包，但是找不到，所以bean valition Factory错误。
