关于spring 框架通过读取配置文件连接数据库 的异常
基本上都是配置文件账号密码,驱动,目标数据库属性配置的错误导致的
Caused by: connection could not be acquired from the uderlying database
Caused by: com.mchange.v2.resourcepool.CannotAcquireResourceException: A ResourcePool could not acquire a resource from its primary factory or source.
我的问题是配置文件中手快多大了几个空格
