发布后，登录出现下面错误，在本地登录也没有这个问题。
2024-02-06 09:22:33.594 [http-nio-9080-exec-2] WARN org.apache.shiro.mgt.AbstractRememberMeManager:449 - There was a failure while trying to retrieve
remembered principals. This could be due to a configuration problem or corrupted principals. This could also be due to a recently changed encryption key,
if you are using a shiro.ini file, this property would be 'securityManager.rememberMeManager.cipherKey' see: http://shiro.apache.org/web.html#Web-RememberMeServices.
The remembered identity will be forgotten and not used for this request.
