一、异常描述

通过jedis客户端代码连接redis服务因默认为操作系统目录（非授权写入操作），报出异常"redis.clients.jedis.exceptions.JedisDataException: ERR operation not permitted"日志，详情如下所示

二、解决步骤

1. 在redis服务目录下设置redis.conf文件,找到dbfilename  dump.rdb行修改为授权目录（E:/xwood/redis-db/,根据实际情况设置），如修改如下

#  ...@b@@b@# The filename where to dump the DB@b@dbfilename  dump.rdb@b@@b@# ...

修改为

#  ...@b@@b@# The filename where to dump the DB@b@dbfilename  E:/xwood/redis-db/dump.rdb@b@@b@# ...

2. 重启redis服务，问题解决了
