耽误半天了，求大神帮忙解决

貌似是你的数据局连接配置出了问题，看看连接地址，还有driver是不是配错了。

一直用的好好的，都没动过，今天上班突然就这样了，公司其他同事的也没问题

Time to wait for an open connection before timing out

(in milliseconds)

cpool.checkoutTimeout=5000

cpool.initialPoolSize=5

Connection pool size

cpool.minPoolSize=2
cpool.maxPoolSize=100

How long to keep unused connections around(in seconds)

Note: MySQL times out idle connections after 8 hours(28,800 seconds)

so ensure this value is below MySQL idle timeout

cpool.maxIdleTime=7200

Acquiring new connections is slow, so eagerly retrieve extra connections

when current pool size is reached
