答
正如在评论中提到的,例外的某些部分缺失。
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository
和:但是,这个问题也可以在堆栈跟踪的第一线发现
org.springframework.data.mapping.PropertyReferenceException: No property lastName found for type User!
所以,你应该检查你的UserRepository
,因为你有一个查询或方法名称即使在User
实体中没有一个属性,也会引用名为lastName
的属性。
您错过了异常跟踪中最有趣的部分。什么是嵌套异常? – alfcope
