在spring项目中使用idea自带的debug是可以运行项目的但是使用jrebel启动项目就报错，报错信息如上。
经过查询资料：https://segmentfault.com/q/1010000006068898
评论区发现:
这是jrebel的一个bug,原因是jrebel不支持高于spring4.2.7以上的版本。
解决办法：
将spring降到4.2.7以下
或者
升级jrebel的版本至最新
然后我查看自己项目中的spring版本，发现确实是高于4.2.7版本的

这是我spring-boot的依赖，显然我不能更换spring的依赖版本，于是尝试更新Jrebel。

然后选中右边的update按钮，更新到最新版本，最后一步重启idea，然后启动项目，发现完美解决问题。
如果没有破解，请继续浏览：

上面是我用URl破解的方式：

邮箱随便填写即可。
但是话又说回来了，Jrebel官方更新的版本中并未说明不支持高版本的spring依赖。
下面是官方更新的所有日志：
