jedis底层链接池相关类图

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)

GenericKeyedObjectPool

PooledObjectFactory

+ makeObject():PooledObject+ destroyObject(PooledObject<T> p)+  validateObject(PooledObject<T> p) boolean+  activateObject(PooledObject<T> p)+  passivateObject(PooledObject<T> p)

JedisFactory

GenericObjectPool<Jedis>
