- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我真的精疲力尽地解决以下错误。非常感谢任何帮助。

最佳答案
好的,问题是condition
是MySQL中的保留字,你可以在here中找到详细信息(或者您可以从该网站获取另一个文档版本)。
根据经验,如果您得到 org.hibernate.exception.SQLGrammarException
,有时是由于 Reserved Words 问题。
还有一个小技巧,建议把sql显示出来,尝试直接在数据库中运行sql,这样会更容易找到sql问题。
你可以在spring boot中使用spring.jpa.show-sql=true
来显示hibernate sql。
