所以我假设它在创建sessionFactory或获取当前会话时遇到了一些问题？我已经尝试过自动连接它，但之后get bean未发现异常。

因此，我最终按照

根据这个问题的建议：

这个问题似乎是因为使用了Springboot，而不是其他教程所遵循的另一个Spring+Hibernate实现。

我认为您应该自动连接您的

private UserDAO UserDAO

在字段或setterI上尝试了该操作。我仍然收到完全相同的错误消息。您能显示第32行在您的

CustomUserDetailsService.java

中的位置吗？它是

com.myapp.classes.User User=userDAO.findByUserName（用户名）

我已经了解到问题在于UserDAOImpl.java中的sessionFactory返回null，我认为您应该自动连接您的
