这里显示jedis报错，是java和redis连接错误，由于是第一次用redis所以不是太懂哪里的问题，在application.yml配置如下：

shiro-redis:enabled: trueredis-manager:host: 127.0.0.1:6379

这里有几个问题：

我的redis是安装在服务器上，所以host的端口地址应该配成服务器的地址
没有写redis的密码
redis的端口是6379，服务器没有开放，去阿里云服务器上修改一下
修改redis的配置，允许远程登陆：修改修改Redis配置文件redis.conf（我的是在根部录下），找到bind那行配置并#注释掉：

bind 127.0.0.1

改为：

bind 0.0.0.0

但是修改之后还是有问题，显示的是另一个错误了，应该是安装redis并没有配置全，所以出错，连接同学的redis就没有出现问题。

这是连接同学的redis：

shiro-redis:enabled: trueredis-manager:host: tongxuepassword: tongxue

下一步打算把自己的redis卸了重新安装配置
