只有第一次初始化资源池。如果打开连接时探测功能，支持失败重新建立链接的机制
jedis封装的资源池
JedisPoolAbstract
Pool<Jedis>
+ internalPool:type:GenericObjectPool<Jedis>
+ getResource():Jedis# returnResourceObject(Jedis)
哨兵模式的连接池（存在探活进程，会重新初始化commons-pool资源池）
contains
caller
JedisSentinelPool
+ master:type = MasterListener
- initSentinels()- initpool()
此抽象类以及接口，仅仅用作抽取公共代码
JedisPool
+ getResource():Jedis# returnResource(Jedis)# returnBrokenResource(Jedis)
