redis.clients.jedis.exceptions.JedisDataException: ERR unknown command ’ config ’

最近将公司私有云中的微服务项目迁移到腾讯云中，在本地调试一直正常，但是将本地redis修改为腾讯云的redis之后就报这个异常。

完整错误信息如下

关键信息

• Caused by: redis.clients.jedis.exceptions.JedisDataException: ERR unknown command ’ config ’
• RedisSessionConfiguration$SpringBootRedisHttpSessionConfiguration.class

原因如下

1. redis本地版本是3.2，而腾讯云redis是2.8，但是又不可能去升级腾讯云的版本

2. 异常类RedisSessionConfiguration$SpringBootRedisHttpSessionConfiguration.class中的RedisSession

系统中最早的版本用redis做session的共享，但是后面session这一块共享功能是自己手动开发，并没有采用开源的组件。

解决方法：

注释掉spring-session-data-redis相关的jar依赖即可
