当我刷新到一定次数后报错
------解决方案--------------------
请检查代码中是否没有关闭数据连接~
------解决方案--------------------
是否有在finally块里调用你的关闭连接方法？
------解决方案--------------------
 Timed out waiting for a free available connection.
1.连接不够用，性能不行，连接数多设置一些，
2.连接没关闭

------解决方案--------------------
Timed out waiting for a free available connection.
 1.连接不够用，性能不行，连接数多设置一些，
