javax.persistence.PersistenceException: org.hibernate.exception.DataException: could not insert: [com.itcast.bean.product.ProductInfo]

可见com.itcast.bean.product.ProductInfo这个bean有错

org.hibernate.exception.DataException: could not insert:
这个说明你这个bean往数据库里插入数据的时候有错。

请检查这个BEAN相关的插入数据操作

只能看出来是你的插入操作失败了，异常信息指向测试类
