背景
在运行某系统时，在测试类向redis中存入某值，然后取出。
一、遇到的问题
报错：
org.springframework.data.redis.RedisSystemException: 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.

at org.springframework.data.redis.connection.lettuce.LettuceExceptionConverter.convert(LettuceExceptionConverter.java:52)
原因：
二、解决方法
方法1：命令行方式
config set stop-writes-on-bgsave-error no
方法2：修改redis.conf文件
使用docker安装的redis也是类似的。
效果如下：
