解决方案就是在sessionFactory中添加下面一行配置即可

<property name="hibernateProperties"><props><prop key="dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="show_sql">true</prop><prop key="format_sql">true</prop><prop key="hbm2ddl.auto">update</prop><prop key="current_session_context_class">thread</prop><!-- 解决org.springframework.beans.factory.BeanCreationException错误添加的代码 --><prop key="javax.persistence.validation.mode">none</prop></props>
</property>
