我给环境变量，会影响数据库连接吗
----------------解决方案--------------------------------------------------------
驱动啊驱动~
----------------解决方案--------------------------------------------------------
我导入了呀！昨天我都用的好好的,今天改了一下环境变量就不行了java.sql.SQLException: No suitable driver
----------------解决方案--------------------------------------------------------
你改的是哪个环境变量呀?
----------------解决方案--------------------------------------------------------
没有驱动啊!还是不要配了,每次做的时候把他加进去吧!不然环境变量一改出了错都不知道是怎么回事!
----------------解决方案--------------------------------------------------------
为啥不用数据库连接池？方便，迅速，代码通用性好
----------------解决方案--------------------------------------------------------
对，做网站就需要连接池技术的
