redis之org.springframework.data.redis.RedisSystemException: Error in execution

所遇所思2023-11-13 21:44

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：

复制代码 
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:54)
	at org.springframework.data.redis.connection.lettuce.LettuceExceptionConverter.convert(LettuceExceptionConverter.java:52)

原因：

因为强制把redis快照关闭了导致不能持久化的问题，通过stop-writes-on-bgsave-error值设置为no即可避免这种问题。

二、解决方法

方法1：命令行方式

通过远程连接redis，然后使用命令行工具进行配置

复制代码 
 config set stop-writes-on-bgsave-error no

方法2：修改redis.conf文件

vim打开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设置为no即可。

使用docker安装的redis也是类似的。

效果如下：
