Shiro实现分布式会话SessionManager
代码结构：代码结构和SpringBoot整合Shiro中的案例相同
问题：如图
解决思路：将当前的session会话存到缓存Redis中
实现步骤：
- 创建RedisSessionDao extends AbstractSessionDAO
- 配置ShiroConfig
代码实现：
-
RedisSessionDao
public class RedisSessionDao extends AbstractSessionDAO { @Autowired private RedisTemplate redisTemplate; //创建会话 @Override protected Serializable doCreate(Session session) { Serializable sessionId = generateSessionId(session); assignSessionId(session, sessionId); redisTemplate.opsForValue().set(sessionId,session); return sessionId; } @Override protected Session doReadSession(Serializable sessionId) { return (Session) redisTemplate.opsForValue().get(sessionId); } @Override public void delete(Session session) { redisTemplate.delete(session.getId()); } @Override public Collection<Session> getActiveSessions() { return Collections.emptySet(); } @Override public void update(Session session) { redisTemplate.opsForValue().set(session.getId(),session); } }- 1
