同学你好
1、根据报错显示无法连接到Redis。
建议同学看看有没有启动Redis服务器,是否关闭了防火墙,再启动服务,访问试试。
如果问题没有解决,建议同学设置一下连接超时时间,参考代码如下:
#连接超时时间为5秒 spring.redis.timeout=5000
2、根据报错信息显示是,由于redis的保护模式开启了,并且没有绑定ip地址,没有密码认证
根据提示,是需要将 protected-mode yes 改为:protected-mode no
同学是通过配置文件的方式修改的吗,如果是,修改完是否重启服务了,这种方式是需要重启服务才能生效的
如果是通过命令行的方式是不能重启服务的,重启后失效
建议同学通过对应的方式来操作下试试
祝学习愉快~

报错变成了:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer' defined in org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration: Invocation of init method failed; nested exception is org.springframework.data.redis.RedisSystemException: Redis exception; nested exception is io.lettuce.core.RedisException: io.lettuce.core.RedisConnectionException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside. at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1771) ~[spring-beans-5.1.13.RELEASE.jar:5.1.13.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:593) ~[spring-beans-5.1.13.RELEASE.jar:5.1.13.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(Abstr
