Could not get JDBC Connection

Could not get JDBC Connection; nested exception is java.sql.SQLException: Connections could not be acquired from the underlying database!

The error may exist in com/system/mapper/UserloginMapper.xml

The error may involve com.system.mapper.UserloginMapper.selectByExample

The error occurred while executing a query

可以帮忙解释下这是为啥吗？

IDEA版请求

👌

提问

请问这个是直接导入maven项目吗？

问题1：“The project cannot be built until build path errors are resolved”

这个问题怎么解决？

JSP很多页面跳转不了，跳转目标页面还有目录下不存在的名称

把项目导入Myeclipse以后所有的Spring配置文件报XML错误

把只能使用本地的xml的勾去掉就好了

登录出错

输入管理员账号和密码，不能登录，报错，shiro 的 token获取不到账号和密码。

登录

您的账号密码 是有错误吗？？我开始就登录不上去，，这密码？？admin 123???
