Caused by: org.hibernate.exception.DataException: could not insert: [com.itcast.bean.product.ProductInfo]

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 参考技术A 只能看出来是你的插入操作失败了，异常信息指向测试类

原来可以编译过的工程，现在提示 IntelliSense: 应输入声明；而且很多行都有这个错误！不知道是啥原因？

参考技术A 工具-〉选项-〉文本编辑器-〉c/c++->高级-〉禁用自动更新改为：TRUE 参考技术B 没有定义变量直接使用就是这个错误来自：求助得到的回答 参考技术B

我也出现了类似问题，贴出了供大家参考：
