これは、redis Q から値にアクセスするために使用される私のコードです。 

Jedis jedis = null;
try
{
int maxActive = 1000;
int maxIdle = 5;
int minIdle = 1;
long maxWait = 5000;

JedisPoolConfig config = new JedisPoolConfig ();
config.setMaxActive (maxActive);
config.setMaxIdle (maxIdle);
config.setMinIdle(minIdle);
config.setMaxWait (maxWait);
config.setTestOnBorrow (false);
pool = new JedisPool (config, RedisServerURL) ;

jedis = pool.getResource();
jedis.getClient().setTimeoutInfinite();
redisQMesssage = jedis.rpop(RedisQ);
//my code           
}
catch (Exception e) 
{
e.printStackTrace();
}
finally{
pool.returnResource(jedis); 
pool.destroy();
}

上記のコードは 3 つのワーカー スレッドにあります。私は 3 つのワーカー スレッドを 40 回呼び出しています (合計)。
まれに 1/5 回、「プールからリソースを取得できませんでした (SocketTimeoutException:)」というエラーが表示されます。
