Could not open JDBC Connection for transaction; nested exception is com.alibaba.druid.pool.DataSourceClosedException: dataSource already closed
看下为什么jdbc连接关闭了，是不是你自己关闭了然后又去访问，或者连接配置不对，没有打开。
this web application instance has been stopped already你是不是开启了自动加载？手动重启tomcat看下看看，如果不行，贴日志
应该是取不到数据源 ，先检查配置文件，然后cmd试试本地能不能连上数据库，数据库版本或者jdbc相关的jar的版本都有可能导致这个问题
本地都能连上数据库，昨天还好好的，今天启动这个项目就成这样了，tomcat也重新删除在添加，还是这有
你连的是本地的mysql数据库还是远程的？然后看一下mysql的服务有开吗？在任务管理器里面查看——》服务
本地是ssh跳转链接的吗？Bitvise SSH Client用这个软件映射就可了
他报的非法路径啊。你看看你的路径配的有没有问题
DruidDataSource是不是在这里面配的 数据库连接 仔细检查一下
应该是tomcat的问题，tomcat中的插件没有运行起来，如果重启tomcat不好使的话就换一个版本的tomcat试试
Could not open JDBC Connection for transaction
是不是你的IP地址发生变化了

看看这篇文字跟你的问题是一样的。。他写的比较详细,我就不多说了
原因是：因为在定时器中手动获取了 DataSource，然后使用后关闭了或者用完后长期不再用被连接池自动关闭
记得给悬赏。3Q
