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。
