1.錯誤回顯：Error in execution; nested exception is io.lettuce.core.RedisCommandExecutionException: MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
2.解決方法：
究其原因是因為強制把redis快照關閉了導致不能持久化的問題，在網上查了一些相關解決方案，通過stop-writes-on-bgsave-error值設置為no即可避免這種問題。
有兩種修改方法，一種是通過redis命令行修改，另一種是直接修改redis.conf配置文件
命令行修改方式示例：
127.0.0.1:6379> config set stop-writes-on-bgsave-error no
修改redis.conf文件：vi打開redis-server配置的redis.conf文件，然后使用快捷匹配模式：/stop-writes-on-bgsave-error定位到stop-writes-on-bgsave-error字符串所在位置，接着把后面的yes設置為no即可。
