Error creating bean with name ‘enableRedisKeyspaceNotificationsInitializer‘ 报错处理

背景

由于公司从阿里云redis迁移到新的redis地址，导致服务发布报错具体报错内容如下

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

直接出解决方案

如果你的pom文件中有如下dependency

		<dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
        </dependency>

直接ctrl+/，看一下项目是否run successful

启动发生这种run error的几种原因

发现问题之后我在网上找了很多资料，有如下几个case

• 1 SpringBoot中用Jedis来访问Redis，其中Redis是采用集群

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。

error的核心信息如下：

Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer' defined in class path resource

解决方案

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。

• 2.非springBoot集成的redis 如下

服务器关闭后又重启，在上面启动web应用日志打印报错，Error creating bean with name ‘enableRedisKeyspaceNotificationsInitializer’，在网上搜了一下，发现答案很多都是，springBoot相关Redis注解导致的，还有就是要设置一下Redis。
但问题来了我这个不是SpringBoot，而且不存在Redis设置的情况，因为之前是好的。翻了很久，没一个靠谱的突然想一想会不会问题出在Redis上面，要不先看一下Redis进程情况，
ps -ef | grep Redis
果不其然Redis根本没启动，先打开Redis服务再看看，看会不会与变化，报错会不会改变
找到Redis位置
find -name redis-cli
(如果Redis或者其他服务启动的时候，可以通过 ps -ef | grep XXXX,找到进程号如12345，ll /proc/12345/cwd 找到对应的服务位置。)
启动Redis服务
到对应的路径下面启动服务
redis-server …/redis-conf
(这里要注意redis-server 和 redis-conf 的路径，有的是同一级，有的不在同一级。)
服务启动，web 应用进程杀掉重新启动，无报错。所以这个报错的原因里面和Redis服务是否启动有关。
原文链接：（https://blog.csdn.net/feichangwurao/article/details/103169226）

其中报错信息中还有一句重要这样的话

Caused by: org.springframework.dao.InvalidDataAccessApiUsageException: ERR unknown command 'CONFIG'; nested exception is redis.clients.jedis.exceptions.JedisDataException: ERR unknown command 'CONFIG'

Caused by: redis.clients.jedis.exceptions.JedisDataException: ERR unknown command 'CONFIG'

error的原因是：

原因是spring-session调用了CONFIG命令来配置Keyspace notifications功能。而线上环境的redis基于权限的考虑，禁止应用服务执行CONFIG命令，这样就导致了应用在初始化时抛出此异常。

解决方案

我的服务pom文件中有如下依赖
case 1

        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
        </dependency>

注释掉pom文件中的依赖

case 2
发送这个error的根本原因是redis的版本问题。
如果版本太低升级版本。
如果不知道版本的话。。。3.2版本可以解决这个问题、

case 3

代码中取消SpringSeesion对 CONFIG命令的操作

@Bean
public static ConfigureRedisAction configureRedisAction() {
  return ConfigureRedisAction.NO_OP;
}
