连接池基本原理:连接池最基本的思想就是预先建立一些连接放置于内存对象中以备使用。对于多于链接池中链接数的并发请求，应在请求队列中排队等待。并且应用程序可以根据链接的使用率，动态增加或减少池中的链接数。达到链接的优化。 -The basic principles of connection pooling: connection pooling basic ideology is the pre-established links with objects placed in memory for use. For more than a few links to the pool of concurrent link request, the request should be in the queue waiting. And applications can be linked to utilization, dynamic increase or decrease in the number of links to the pool. To achieve the optimal link.
