连接数据库Oracle12c异常解决：Connections could not be acquired from the underlying database

Caused by: java.sql.SQLException: Connections could not be acquired from the underlying database!

之前本地使用的oracle11g，结果服务器上来了一个Oracle12c，瞬间就连不上了，害得我花费了好几天时间。

具体解决方案如下：

首先ping 或者telnet数据库看是否是通的，如果不通那累死也连不上呢。

其次确认驱动版本，尽量使用6以上版本

最后确认数据库连接写法，正确写法为：jdbc:oracle:thin:@//127.0.0.1:1521/orcl

然后再次尝试
