IDEA运行现有SSH框架的WEB项目报错

用IDEA运行已经写好的web项目,此前也成功运行。
今天在用相同的方式却无法运行,报错如下:

三月 25, 2020 8:07:29 下午 org.apache.catalina.loader.WebappClassLoaderBase clearReferencesJdbc
严重: The web application [] registered the JDBC driver [com.alibaba.druid.proxy.DruidDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

严重: The web application [] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
[2020-03-25 08:07:29,948] Artifact web_new:war exploded: Error during artifact deployment. See server log for details.

背景:

IDEA,web为SSH架构,tomcat7.0.82
此前运行没有问题。

tomcat log:

    1、检查下数据库是否正常启动;
    2、jdbc连接配置如端口、用户名和密码等是否跟数据库一致?

    数据库没有连接上
    如果之前一直都好使,有时候是已重新开机就连接不上的情况,可能是数据库被电脑关闭了图片说明这种情况就需要手动打开
