shiro redis 集群 session无法登陆?报错
登陆时2个tomcat打印的sessionid是一样的，可是redis没有。跟踪了一下代码刚开始进入doReadSession方法查询redis无数据后就报错了 org.apache.shiro.session.UnknownSessionException: There is no session with id【xxxxx】然后跳转到doCreate方法生成新的sessionid。就登陆不了 不知道哪里出错了。
我的配置

复写 JSESSIONID 同时由于shiro的原因你会发现系统访问一次url会多次调用doReadSession方法产生大量的redisio读取，建议在doReadSession方法添加二级缓存~
回复 @吃不饱:可尝试一下google的guava大神有doReadSession二级缓存的思路吗和资料吗你用ehcache了,那么问题来了,你ehcache做集群配置了吗?ehcahe没做集群，目前这问题还没涉及到ehcahe我连登陆都登不了@全体大神们帮帮忙单机是先进savasessionId方法在进doReadSession可以正常登录，集群是先进doReadSession方法导致获取sessionId和保存的id不一样大神们怎么解？2020-06-09 10:35:07赞同 展开评论 打赏
