Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer' defined in class path resource
我们在SpringBoot中用Jedis来访问Redis,其中Redis是采用集群(单机没有本篇文章的问题)的方式,在启用Redis的时候碰到如上问题。
错误的核心信息如下:
Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer' defined in class path resource
完整信息如下:

经查找,在Java代码中,我们使用了注解:@EnableRedisHttpSession,这个注解是用来开启Redis来集式式管理Session。
而在使用这种方式的时候,是需要Redis开启Keyspace Notifications功能的,默认是关闭的。
这个功能有一个参数来控制它,notify-keyspace-events,值为Egx。
可以通过在Redis.Config中配置。
也可以通过命令行来配置,如下所示:
redis-cli config set notify-keyspace-events Egx
然后重启Redis生效。
