redis实现共享对象锁 redis 共享

SpringBoot+Shiro基于Redis实现共享Session

项目发布到微服务k8s里，发现容器数量为1的时候 能正常登录，而当容器数量调整到多个的时候就会发现登录不了。 经排查是多个容器的时候Session会话没保持，就需要在多个应用的时候共享session会话。

上一篇2020-04-01-Shiro Session集群共享存入Redis中SimpleSession的transient 属性不能序列化已经提到了集成redis实现共享session的坑！！ 这里我就不用自己去 RedisManager、SessionDAO了，而是使用shiro-redis 框架。

下面通过实现一个小Demo，来说明如何使用并集成shiro-redis！

一、实现步骤

二、本地测试

通过nginx 启动两个不同端口的jar（8081、8082）

upstream myapp{
    server 127.0.0.1:8081 weight=1;
    server 127.0.0.1:8082 weight=1;
}

server{
        listen       80;
        server_name  myapp;

        location / {
            proxy_pass http://myapp;
            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        }
}

项目启动会，访问登录 就会发现cookie里存在SHAREJSESSIONID了 redis里也有对应的SessionId了。

三、生产环境&ShiroConfig配置

很多时候生产环境的redis都是集群化，这里的配置就有一点不同。

下面贴一下我公司项目的ShiroConfig配置，跟上面的demo不是一回事 大体思想还是一致的。
