Spring应用程序在8小时后失去与MySql的连接。如何正确配置？

I've got a Spring app that I believe uses DBCP connection pooling to connect to a MySql database. I say believe because this isn't an area I'm very strong in and I'm not positive if everything is set up correctly. I have no problems running the application and everything is working fine. The problem occurs overnight. The app is not heavily used and overnight it apparently loses it's connection to MySql. I looked into it and found out MySql has an 8 hour window and then it disconnects or whatever. I'm fine with this, but when a user attempts to log on in the morning, they get an error something like:I've got a Spring app that I believe uses DBCP
