spring-session通过redis实现session共享

依赖：

        
            org.springframework.boot
            spring-boot-starter-data-redis
        
        
        
            org.springframework.session
            spring-session-data-redis
        
        
        
            org.springframework.session
            spring-session-jdbc
        

配置：

spring:
    session:
        store-type: redis
        timeout: PT30M
    redis:
        host: 192.168.2.22
        port: 6397

通过sessionId删除指定session：

    public void removeSession(HttpServletRequest request, String sessionId) {
        HttpSession session = request.getSession();
        if (Objects.equals(sessionId, session.getId())) {
            session.invalidate();
            return;
        }
        Object sessionRepositoryAttribute = request.getAttribute(SessionRepositoryFilter.SESSION_REPOSITORY_ATTR);
        if (sessionRepositoryAttribute == null) {
            return;
        }
        SessionRepository sessionRepository = (SessionRepository) sessionRepositoryAttribute;
        if (sessionRepository.findById(sessionId) == null) {
            return;
        }
        sessionRepository.deleteById(sessionId);
    }
