解决:Redis:java.util.NoSuchElementException: Unable to validate object at

解决:Redis:java.util.NoSuchElementException: Unable to validate object at

在Java使用Redis的过程中遇见了一个问题,

redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool at

Caused by: java.util.NoSuchElementException: Unable to validate object at

这个问题是说拿不到Redis的链接,因为validate通不过。登录一个客户端,手动ping一下

127.0.0.1:6379> ping
(error) MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error.
貌似是RDB持久化的问题。

解决方法,使用redis-cli修改rdb目录

CONFIG SET dir /tmp/redis_data
CONFIG SET dbfilename temp.rdb
重启redis-server,问题解决!

上面的解决方法需要每次启动server都要修改rdb的路径。

另一种解决方法是直接修改redis.conf文件,修改如下两行:

dir /tmp/redis_data #./ –> /tmp/redis_data
dbfilename temp.rdb #
启动redis-server

/opt/redis-3.2.1/src/redis-server /etc/redis/redis.conf
问题解决!

OK!
