Question

我正在使用Spring Boot + Spring Security + Rest API + JWT 尝试将项目配置为从psql数据库中获取值以授权用户。

该应用程序正在启动，但启动时出现以下错误。

堆栈跟踪：

缺少什么？我需要更多有关该问题的信息吗？我一直在寻找答案，但没有一个确切的答案。我尝试更新Maven并更改休眠版本

Answer 1

我遇到了相同的错误。但是我需要更新的Springboot 2.0.3发行版中的一些库，所以我删除了这一行

ad_id  price       date
7     22      2 2018-06-11
6     23      2 2018-06-22
2     24      2 2018-06-30
3     28      5 2018-06-22

这是导致异常的类，我还没有找到更新的版本，以防万一我需要会话处理。但是我更喜欢使用@Transactional进行会话处理，所以在那里没有问题

引起原因：java.lang.ClassNotFoundException：无法加载请求的类：org.springframework.orm.hibernate4.SpringSessionContext
