redis使用连接池报错解决

redis使用十几小时就一直报异常

redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
at redis.clients.util.Pool.getResource(Pool.java:22)
at com.derbysoft.jredis.longkeytest.BorrowObject.run(BorrowObject.java:22)
at java.lang.Thread.run(Thread.java:662)
Caused by: java.util.NoSuchElementException: Timeout waiting for idle object
at org.apache.commons.pool.impl.GenericObjectPool.borrowObject(GenericObjectPool.java:1134)
at redis.clients.util.Pool.getResource(Pool.java:20)

原因是没有回收资源导致
正确的做法是

ShardedJedis jedis = shardedJedisPool.getResource();
try {
	jedis.set(key, value);
} finally {
	shardedJedisPool.returnResource(jedis);
}
