SpringBoot+Shiro+Redis共享Session入门小栗子

2023-07-22 14:04:40

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）

下载Nginx

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
