在spring会话到期之前执行自定义事件

是的，您可以使用SessionDestroyedEvent做到这一点。

@Componentpublic class SessionEndedListener implements ApplicationListener<SessionDestroyedEvent> {    @Override    public void onApplicationEvent(SessionDestroyedEvent event)    {        for (SecurityContext securityContext : event.getSecurityContexts())        { Authentication authentication = securityContext.getAuthentication(); YourPrincipalClass user = (YourPrincipalClass) authentication.getPrincipal(); // do something        }    }}

并在web.xml中：

<listener>    <listener-class>        org.springframework.security.web.session.HttpSessionEventPublisher    </listener-class></listener>

常规注销和会话超时都会触发此事件。
