无法从池中获取资源(SocketTimeoutException:) [英] Could not get a resource from the pool(SocketTimeoutException:)

问题描述

我正在运行多个工作线程(大约 10 个)来访问来自 redis Q 的数据.
对于我正在为 Jedis 客户端 使用无限超时.

I'm running multiple worker threads(around 10) to access the data from the redis Q.
For the i'm using infinte timeout for Jedis Client.

Jedis jedis = pool.getResource();
jedis.getClient().setTimeoutInfinite();  

我仍然收到错误无法从池中获取资源". 下面给出了堆栈跟踪.

Still i'm getting the error "Could not get a resource from the pool". The stacktrace is given below.

推荐答案

我注意到如果 Redis 没有运行，这个异常会并且将会被抛出.提个醒.

I noticed that this exception can and will be thrown if Redis is not running. Just a heads up.
