spring boot 项目部署在Docker中调用redis出现的奇怪问题

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer' defined in class path resource [org/springframework/session/data/redis/config/annotation/web/http/RedisHttpSessionConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectio

以上是在Docker环境部署后页面上展示的错误，不用Docker直接用java -jar jar包名称的形式启动完全正常

解决方法

1 进入Docker容器

2 安装redis(我用的是ubuntu)

apt-get update
apt-get install redis-server
#启动redis
redis-server /etc/redis/redis.conf

3然后就正常啦
