springboot报错:org.springframework.beans.factory.BeanCreationException

今天报了这样的错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'xxx': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.

bean创建失败了,找了很久,发现是自动生成的代码中xml文件里的sql有问题,再遇到此类问题记得检查一下sql是否正确
