请问这是什么错误?
Timeout expired.请问这是什么错误,我被困扰了好久了.help me! thank you!
错误信息如下:
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
每次实例化个实例conn后,我都有去关闭的conn.close(),但打开网页,查看几次后,总会出现以上的毛病,为什么呢?
