使用hibernate时出现 org.hibernate.HibernateException: Unable to get the default Bean Validation factory

hibernate 在使用junit测试报错：

解决方案：

hibernate.cfg.xml中配置的时候  增加如下配置

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

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <!-- 配置会话工厂（hibernate核心对象，管理数据库连接池） -->
    <session-factory>
        <!-- 连接数据库 JDBC 四个基本连接参数 -->
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql:///hibernate</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">111</property>
        
        <property name="javax.persistence.validation.mode">none</property>
        
        <!-- 配置hibernate 使用 数据库方言 -->
        <!-- 方言解决 不同数据库 之间区别 -->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        
        <!-- 其它属性 -->
        <!-- 自动建表 -->
        <property name="hibernate.hbm2ddl.auto">update</property>
        <!-- 在日志中输出SQL -->
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.format_sql">true</property>
        
        <!-- 事务默认操作 -->
        <property name="hibernate.connection.autocommit">false</property>
        
        <!-- 配置c3p0 -->
        <property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
        
        <!-- 加载hbm映射 -->
        <mapping resource="cn/ustc/domain/Customer.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

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beanvalitionFactory错误。
