redis运用连接池报错解决

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);
}
