关于的解决Connections could not be acquired from the underlying database!的异常报错
当然网上有各种解决办法，一下是我复制粘贴的

连接数据库参数配置是否正确

查看连接的url 用户名密码是否正确 ,密码是否过期

查看数据库server是否处于运行状态

如server没有启动重启server
检查到数据server的网络连接是否正常
连接到数据库server的连接数是否已经达到最大连接数
1. 如已经达到最大连接数,检查程序是否使用连接后没有释放
2. 上调数据库最大连接数设置

当然这些都没有解决我的问题
最后发现是jar包版本太低的原因导致的，索性将jar包直接引入为8版本的，完美解决问题
