java - 由 : java. lang.ClassNotFoundException : Could not load requested class : org. springframework.orm.hibernate4.SpringSessionContext 引起

Question

我正在使用 spring boot + spring security + Rest API + JWT尝试配置项目以从 psql 数据库获取值来授权用户。

应用程序正在启动，但我在启动时收到以下错误。

堆栈跟踪:

缺少什么？我需要了解该问题的更多信息吗？我一直在寻找答案，但没有找到与此完全一样的答案。我尝试更新maven并更改hibernate版本

Answer 1

我遇到了同样的错误。然而，我需要更新的 Springboot 2.0.3 版本中的一些库，所以我删除了该行

spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

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 session 处理。不过，我更喜欢使用 @Transactional 进行 session 处理，所以没有问题
