SpringBoot+Shiro+Redis共享Session实例

作者:小LUA

在单机版的Springboot+Shiro的基础上,这次实现共享Session。

这里没有自己写RedisManager、SessionDAO。用的 crazycake 写的开源插件

以上两种配置各打包一次(记得留着打包好的jar包)

解压到无中文目录,修改Nginx配置文件

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;
            }
    }

到此,先启动两个jar包(分别是8081,Node-One;8082,Node-Two)

然后启动Nginx

浏览器访问:http://localhost/

刷新看看..

随便在一个节点上注册,登录,然后刷新到另外一个节点,发现不用登录就可以访问权限资源
